Problem Statement: How can a Custom Table be exported and imported between different simulations? | Solution: In order to export a Custom Table, you can right-click on the Custom Table name on the Navigation Pane and select ‘Export' option. When the Save window appears, save this giving it any name. The file will be saved on a .bkp extension format.
Then, in order to import previously saved Custom Table into another simulation, go to File | Import | File (Import a file to the current workspace), then select the .bkp file that you saved in a previous step. Now the table will be imported and located under Flowsheet | Custom Tables, in order to be used on this simulation.
Note: The imported custom table will be ready to use with specified variables only if the name of the blocks and streams related to this custom table are the same. In case of any change in the name of the variables in the imported custom table, those should be specified again.
For further details, find attached a video which illustrates clearly this procedure in Aspen Plus.
Keywords: Custom Tables, Export, Import.

Problem Statement: How can I model 3-phase distillation column in Aspen HYSYS? | Solution: In order to rigorously solve a distillation column which has multiple liquid phases, you need to use the Sparse Continuation Solver and select the 2 liquid check on Parameters | Solver.
Then, go to the 2/3 Phase page and enable two phase checking on the trays where two phases were reported. Checking for liquid phases in a three phase distillation tower greatly increases the solution time. Typically, checking the top few stages only provides reasonable results.
The 2nd Liquid Type radio button allows you to specify the type of calculation Aspen HYSYS performs during checking for a second liquid phase. When the Pure radio button is selected, Aspen HYSYS checks only for pure water as the second phase. This helps save calculation time when working with complex hydrocarbon systems. If you want a more rigorous calculation, select the Rigorous radio button.
By default, Aspen HYSYS selects Pure for hydrocarbon distillations, and Rigorous for chemical based distillations. This default selection criteria is based on the type of fluid package used, but you can always change it.
Attached is a sample of how to model a 3-phase column distillation which has a wter and acetic acid feed stream and an ethyl acetate makeup stream used to separate the water from the acetic acid.
Note: if the column fails to converge with Sparse Continuation Solver, refer to Solution ID 122462

Problem Statement: The Aspen SQLplus (SQLplus) web reporting tool may give users access errors when attempting to create or save reports. Although the errors may vary, they typically report problems similar to the following:
Error generating report "Test"
Error loading template file: C:\Program Files\Common Files\AspenTech Shared\SQLPlus\xsl\common\main.xsl Access to the path "C:\DOCUME~1\<nodename>\ASPNET\LOCALS~1\Temp\vgmxppbr.o.js" is denied | Solution: The SQLplus web reporting tool uses Microsoft's .NET Framework, which requires the ability to write files to a couple of temporary directories. Specifically, users will need "Read & Execute", "Read", and "Write" permissions to the following directories on the SQLplus web server:
C:\Documents and Settings\<nodename>\ASPNET\Temp C:\WINDOWS\Microsoft.NET\Framework\<.netversion>\Temporary ASP.NET Files\sqlplus
It is important to note that the SQLplus web reporting tool is configured to allow anonymous authentication by default. When a virtual directory allows anonymous authentication, all users are identified as the server's local IUSR_<nodename> account, therefore the IUSR_<nodename> account by default will require permission to the above mentioned directories.
It is possible to use authentication on the SQLplus virtual directory so that the end user is actually identified by their proper domain account. To change the authentication of the SQLplus reporting tool:
1. Go to Start | Run then type "inetmgr"
2. Expand the local computer | Web Sites | Default Web Site
3. Right-click on the SQLplus virtual directory and select Properties
4. Navigate to the Directory Security tab
5. In the Anonymous Access and Authentication Control section, press Edit
6. Deselect Anonymous Access if it is selected
7. Select one form of authentication, either Basic Authentication or Integrated Windows Authentication (Basic Authentication will require that the user specifies their name and password with each new IE session; Integrated Windows does not require a login as it will request the login information from the Operating System of the client machine.)
8. Once the appropriate mode of authentication is selected, press OK to close the dialogs and the Internet Information Services console
If the authentication mode has been changed, all domain user accounts intending to access the SQLplus reporting tool will need to be given NTFS permissions to the two directories on the SQLplus Web Reporting server. If your IT policy allows, the "everyone" account can be given permission as opposed to adding individual domain accounts or domain groups.
NOTE: If security has been implemented on InfoPlus.21 or on the SQLplus application, the authenticated user of the SQLplus web reporting tool will also need to belong to an AFW role with permission to read data from the specified server. This permission is in addition to the NTFS permissions required to properly run the web reporting tool, as mentioned in this Knowledge Base article.

Problem Statement: In some DMC3 Builder applications, changes made in the deployment section would not save. Before any changes in this section is saved, the limits for all variables are validated for cross and unreasonable values. Any error in the online settings would prevent any changes to be saved.
Once the Online Settings is called up with any pre-exsiting error, the user will get a message about validation error.
This message only appears when the Online Settings is displayed. | Solution: Before leaving the deployment section, check the online settings and address any validation error to ensure changes are being saved.
In future releases, a warning message will appear if the online settings have validation error when the user tries to save changes in the deployment section

Problem Statement: How does HYSYS Lee-Kesler method handle steam enthalpy when calcuting the mixture enthalpy. | Solution: The mixture enthalpy is the mole-weighted average of the enthalpy of the dry fraction (calculated using Lee-Kesler) and the steam (using ASME steam tables).
The dry fraction enthalpy is calculated at the system (i.e. total pressure).
For steam, enthalpy is calculated at steam partial pressure for vapor pressure and for liquid phase, enthalpy is calculated at liquid partial pressure.
Keywords: steam, Lee-Kesler, Enthalpy.

Problem Statement: How Aspen HYSYS calculate the water mole fraction content in the effluent Naphtha stream from the Crude Distillation Unit (CDU)? | Solution: Naphtha is a draw stream from 3-phase condenser. Moreover, the 3-phase condenser is just a column stage and in each stage, Aspen HYSYS will make sure that each of the component flows and the heat flow in and out will be balanced for each stage. Also, for the 3-phase condenser (vapor-liquid-free water phase) are in equilibrium. That's how Aspen HYSYS calculate the column and obtained each component flow.
In 3-phase condenser, most of the water will go to the free water draw phase, but maybe small amount of water can still go to liquid phase, such as in this case Naphtha draw.

Problem Statement: To run OTS OPC server capabilities, DCOM privileges should be correctly configured. | Solution: AspenOPCSimServer Service is the windows service related to the OPC server activation on OTS. Account used for running this service must have DCOM privileges. To configure DCOM permissions:
Open Windows Component Services and navigate to DCOM folder.
Navigate to AspenOPCSimServer component and open its properties
Verify that the service account is used as Identity on the DCOM Identity tab.
Verify that the service account has Launch, Activation, Access and Configuration permission under the DCOM Security tab.

Problem Statement: When running OTS as an application it uses two executable files to setup the dynamic simulation:
AspenHysys.exe
Aspentech.AspenOts.Executive.exe
Unfortunately, these two processes run on the account they were open with, and when logging off from this account they stop. To avoid this behavior, one may want to run OTS as a service, this way the Hysys simulation and OPC service will run continuously even when logging off. | Solution: To run OTS as a service is necessary to install AspenTech.AspenOts.DeployService.exe on the server.
Run Installutill.exe from a command prompt. This can be found on C:\Windows\Microsoft.NET\Framework\V4.0.30319
The executable to install the service can be found at: C:\Program files (x86)\AspenTech\OTS Framework V9.0
This is an example of the command:
** Note : More details can be found on the help file of OTS Framework, under Running OTS Framework as a Windows service.
Running OTS through Windows services:
Once the service is installed we can run AspenHysys.exe and Aspentech.AspenOts.Executive.exe directly from windows services without the need to open Aspen OTS program. To do that:
Verify AspenOPCSImServer service is running and has correct permissions on DCOM.
Open windows services and open Aspen OTS deployment service properties.
Be sure to be using the same account used on AspenOPCSimServer and the one that has permissions for DCOM.
On the Start Parameters write the path for the OTS file (*.aots). If possible avoid special characters on the aots file. Backslash (\) is used as a escape character. The correct path needs to be written as the following example:
Click the Start button inside of the properties windows, to start the service with the provided Start parameters.
** Start Parameters should always be written if the service is restarted, this value will not be saved.
If OTS service is started correctly AspenHysys.exe and Aspentech.AspenOts.Executive.exe processes should be running on the background (Confirm this on Task Manager). If AspenHysys.exe is not running it is possible that the path is not set correctly.

Problem Statement: How to resolve corrupted ASW files? | Solution: Two types of data corruption possible:
Type 1: When opening the workbook you get the following error:
Caused by crash or error in Excel, ASW or linked simulator while saving the workbook;
Usually not able to recover workbook.
Solution:
Use Verify Workbook Data Before Saving option in Organizer | Application page;
Save workbook often using Workbook Backup and Save options:
Type 2: Corruption due to variable mismatch error upon opening:
Not as serious as previous corruption type;
Internally variable information is stored in two locations;
Mismatch between locations will trigger the error;
Caused by simulation crash or error.
Solution:
ASW will try to restore corrupted variables (one opportunity):
- Requires being connected to the simulation file(s);
- If prompted, browse to the simulation file so recovery process will proceed.
If successful the workbook will continue to open and work correctly;
If recovery is not successful then the following message will appear:
Re-add variables and re-build tables affected by broken links;
Check to ensure simulations are in the simulation list on the Organizer | Simulations sheet.
Please take a look at the solutions that provide helpful details about the ASW use:

Problem Statement: How can I import a DBR PVTPro files (*.Pro, *.prox) into Aspen HYSYS? | Solution: The user can add DBR PVTPro files (*.Pro, *.prox) files into the Properties Environment using the PVT Environment inside Aspen HYSYS. It does not require a separate PVTPro reader, but to access this feature the user will need the HYSYS Upstream license.
First enter the Properties Environment and select ‘PVT Laboratory Measurements’ from the home riboon tab.
From the PVT Laboratory Measurements window select ‘Add Package’
From list of Selected Engine select ‘DBR PVTPro’
Now click ‘Launch Engine’
From the PVTPro Environment select ‘Open PVTPro Project File’ and browse for the desired file
Note: Aspen HYSYS V9 will be the final version to include the PVTPro technology. Starting with Aspen HYSYS V10, you can no longer select the DBR PVTPro engine to integrate with DBR PVT Pro; For additional information refer to the following article Product Lifecycle Announcement for PVTPro

Problem Statement: How do I check the mapping reference of a Primary Stream after a simulation file is imported and streams are mapped? | Solution: To check the mapping reference of UO streams mapped to Primary streams, follow the next steps:
1) Open the ABE-Explorer and click on the ‘All Streams’ filter, then right-click on the Primary stream of your interest and select ‘Attributes’.
2) Next, click on ‘Options’ and select ‘Show System Attributes’.
3) You will find an attribute named ‘Mapping
Keywords: Explorer, Mapping
References: s’, double-click on it to show the data link between a UO stream and a Primary stream linked pair. The mapping reference can be deleted and therefore the linked objects will be unmapped.
The 'Id' argument shown in the link string refers to the object's OID, which is assigned by ABE-Explorer.
This is a useful way of verifying the data link that exists once simulation streams (UO streams) have been mapped to ABE streams Primary/Process streams). |
Problem Statement: What can cause the error message "The data base file does not have an entry for this valve, scenario or tank" in Safety Environment? | Solution: The safety environment saves almost all of its information in a Microsoft Access database with the same name as the case file (For example, if the case file is named example.hsc, then the database will be named example.mdb). Therefore, it is critically important to keep the access database in sync with the case file. The compound file (.hscz) will package the case file and the database together, so it is recommended using it because it can avoid problems with lost or out of date Safety Environment data.

Problem Statement: Aspen watch (V9 and older) does not allow users to build custom KPI using secondary parameters such as the PV High range parameter (AW_PVH) , proportional gain (AW_DBL1), etc. from PID Loops. Consider an example where a user wishes to map the AW_PVH field of a PID Loop record to a variable in the customer KPI. However when the user opens the Variable Binding window, the PID Loop applications do not show this particular parameter in the Attributes list (see screenshot below). | Solution: To use the AW_PVH parameter in a custom calculation, the user would first need to locate the parameter in the IP21 database using InfoPlus.21 Administrator. We will use the PID loop FC-D2BTM to illustrate the procedure in this KB.
Open IP21 Administrator, and locate the FC-D2BTM record under AW_PIDDef and locate the AW_PVH parameter of this record.
2. Change one of the IODEV devices in the Logical Devices Definition file to communicate with the IP21 database (use CIMIOSETCIM_200 as the DLGP service name).
3. In Aspen Watch Maker add a new Misc tag, name is FC-D2BTM_PVH, choose Cim-IO Device name that contains CIMIOSETCIM_200, set the IO Address: FC-D2BTM AW_PVH. There should be a space between FC-D2BTM and AW_PVH. Click OK to add the tag as a Miscellaneous tag.
4. Now the user can bind the custom calculation variable to this newly created Misc Tag as shown in the screenshot below.

Problem Statement: Does the hydrate formation analysis support high pressure systems? | Solution: The Hydrate Formation Analysis in Aspen HYSYS is able to handle a variety of pressure values, providing reasonable results with its default model Ng & Robinson. The accuracy of the model, however, may be compromised when applied to very high pressure regions (higher than 1000 bar).
Recent work developed by Professor E. D. Sloan’s group at the Colorado School of Mines provides significant improvements on meeting the needs of modeling at greater pressures. For methane, for instance, the new model (CSM) is able to provide good results to hydrate systems formed in environments that reach up to 10000 bar.

Problem Statement: In the calibration mode of the FCC reactor, how does the product sulphur content gets calculated | Solution: In the calibration mode the sulphur content is calculated according to the following equation:
Prod_Sulphur = Feed_Sulphur * parameter * (Feed Sulphur Multiplier + Conversion * Conversion Multiplier + Riser Temperature * Riser Temperature Multiplier + Processed Sulphur * Processed Sulphur Multiplier).
The parameter is calculated so that the product sulphur matches the value from the input curves (these curves are cut into assay like lumps and the base sulphur curve is adjusted so that each product sulphur is matched exactly.
The assay lumps are then grouped by boiling point into square cuts and the product sulphur for each square cut is calculated by multiplying the sulphur curve by the weight composition curve).

Problem Statement: Data cannot be exported to EDR from ABE through the Thermal Design interface, even though both ABE and EDR are locally installed on the PC and EDR works properly. How can I resolve this issue? | Solution: This problem might be caused by an incorrect set version of EDR, which is not the same version as ABE. This is likely to happen when there are multiple versions of EDR and ABE installed on the PC.
The following procedure might resolve this issue:
1) Verify that ABE-Explorer is pointing to the correct ‘AZThermalDesign.exe’ file. To do so, open ABE-Explorer | Tools | Customize. On the Customize Tools dialog, click on ‘&Thermal Design’ and verify that on the ‘Command’ field ABE is pointing to the correct version of the ‘AZThermalDesign.exe’ file (in accordance to the ABE version that is being used) on the following path: ‘C:\Program Files\AspenTech\Basic Engineering VX.X\UserServices\bin\AZThermalDesign.exe’ (‘X.X’ refers to the ABE version that is being used (i.e. V8.8, V9.0...)).
After that, try to export data to EDR.
2) If data is still not able to be transferred, verify that the set version of EDR agrees with that of ABE. To do so, go to: Start | All Programs | AspenTech | Exchanger Design and Rating VX.X | Set Version (‘V.X.X refers to the EDR version that is the same as ABE).
The EDR Set Version application must be run as administrator.
Once the Aspen Exchanger Design and Rating Version Control Utility dialog appears, make sure that the correct version is shown as active (35.0 refers to V9.0, 34.0 to V8.8 and so on). If a wrong version is shown as active check the correct box and then click on ‘Set’. On the other hand, if the correct version is shown as active, click on ‘Fix current version’.
At this point, it should be possible to export data to EDR from ABE through the Thermal Design interface.

Problem Statement: Performing Virtual machine snapshots while controller is running could lead to controller turning OFF. It is recommended that users should prudently avoid enabling virtual machine snapshots when the controller is running. Also please note that automated virtual machine snapshots are not a recommended method for backing up VM data. This KB article explains the reason for controller turn OFFs and directs users to appropriate resources for working around the issue. | Solution: When the VM snapshot event occurs the controller continues to run with invalid inputs due to a timeout in the communications. The invalid values for all of the inputs would cause the controller to turn OFF. This is the correct behavior because if all of the inputs come in with invalid values, the controller cannot perform the necessary control calculations. Both DMCplus and APC controllers see the VM snapshot event as a failure to read data and act appropriately by turning OFF the controller. With all of the inputs being read in as invalid due to the timeout the safest action the controller can take is to turn itself OFF. For this reason taking a snapshot of a VM that has running controllers is not recommended as it would result in an interruption to the controller.
Backup of data can be explored by investigating back up tools which do not interrupt the current applications.
Some virtual machines vendors like VMWare have stated in their KB articles that when creating a VM snapshot, the VM is stunned in order to serialize the device state to disk and then close the running disk to create a snapshot point. Please refer to the VM vendor help files and KB articles to ensure that the applications can continue to run when the VM snapshot is taken.Also it is recommended in VM vendor KB articles that snapshots are not backups and it is not an efficient way to back up the contents of the VM.
Custom bat file can be used to perform automatic backup of important files on the VMs which are used for APC software. The following procedure can be used to schedule this back up activity -
Step 1: Create bat files to perform back up and copy to the folder location of your choice.
Step 2: Open Windows Task Scheduler.
Step 3: Create Basic Task from the Action menu of Task scheduler
Step 4: Under Basic Task: Provide a name for this task like BackupAPC
Step 5: From Trigger menu: Select the frequency for back up - daily/ weekly
Step 6: Select start a program
Step 7: Using the browse button point to StartBackup.bat
Step 8: Click on finish to create the task.
Step 9: Click on Task Scheduler Library folder icon and doubleclick the task which was created, like BACKUPAPC.
Step 10: Select the checkbox which specifies Run with highest priveleges
The above steps should help ensure that the backup of important APC files is always maintained.

Problem Statement: Why does Aspen Exchanger Design and Rating (EDR) asks for the End length as rear head input value, when you specify the Location of Nozzle at U-Bend: Before u-bends?
However, if you set the Location of nozzle: Over u-bends/Beyond U-bends, EDR automatically defines the End length as rear head value as zero. Why? | Solution: End Length at Rear Head (RI) is defined as the distance from the end of the tube to the center of the nearest flow baffle. If this value is set as zero, the program consider that the last baffle is at the tangent with the U-bends, but in reality, it will never happen.
If the nozzle is over/beyond the U-bend end, RI can be very small or zero.
If the nozzle is before the U-bends end, there will be a baffle near the end, which can still have a length of zero to the tangent. That’s the reason you must enter a value to define the position of the last baffle.

Problem Statement: How do you determine the choke flow in a valve in Aspen HYSYS? | Solution: The valve in Aspen HYSYS indicates the choke flow status in the under Rating | Flow Limits page. To determine the choke flow, you can perform a case study with a range of pressure drops. Follow the steps below for choke flow calculations.
Enter the valve size or calculate the size of the valve based on flow rate and pressure drop.
Check the option “Use sizing methods to calculate Delta P. This is located under Design | Parameters.
Create a case study with variables: Valve outlet pressure and Flow rate.
The case study shows the choke flow condition. The flow rate does not increase as you decrease the outlet pressure of the valve.

Problem Statement: Cannot find the ‘DataServices’ folder where the ‘Broker.ini’ file is located. This folder was not installed. Why? | Solution: If the ‘DataServices’ folder is not located under ‘C:\Program Files\AspenTech\Basic Engineering VX.X’ (VX.X refers to the version being used), then it will not be possible for the user to set up the ‘Broker.ini’ file and therefore to either create or manage workspaces. This is likely to happen when the Aspen Engineering Suite (AES) is installed, but not the Aspen Basic Engineering Server.
This means that the ‘DataServices’ folder can only be found under ‘C:\Program Files\AspenTech\Basic Engineering VX.X’ once the Aspen Basic Engineering Server is installed.
To do so, follow the next steps:
1) Launch the ‘Steup.exe’ application as shown below:
2) Since the Aspen Basic Engineering Server has not been installed, once the aspenONE Installer wizard appears, click on ‘Install aspenONE products’ and accept the software license terms.
3) Click on the ‘Server Products and Tools’ drop down button and install the Aspen Basic Engineering Server.
Once the Aspen Basic Engineering Server is successfully installed, verify that both the ‘DataServices’ folder and the ‘Broker.ini’ file are located under ‘C:\Program Files\AspenTech\Basic Engineering VX.X’ and ‘C:\Program Files\AspenTech\Basic Engineering VX.X\DataServices\x64bin' respectively.

Problem Statement: When specifying the Particle Size Distribution (PSD) for a solid component in an inlet stream, the CI Solid tab still appears as incomplete and shows the error:
SUBS-ATTR not complete: SATTSUB = CIPSD
Upper limit of last interval of selected PSD mesh cannot be greater than upper limit of last interval of PSD mesh for this substream (Setup Solids Substreams). | Solution: In some simulations, you might want to have two or more particle size distribution definitions, with different size ranges. This is useful if different sections in your flowsheet have very different particle sizes. You can add and modify particle size distributions using the Setup | Solids | PSD sheet, or directly on the form for a stream.
On the CI Solid or NC Solid sheet of a stream containing solids with a particle size distribution, in the Particle Size Distribution section, you can select what particle size distribution to use for the substream. You can select to define a new particle size distribution and click Edit Mesh to modify the size limits of the intervals in the PSD.
If you use a different mesh than the one defined in this stream's stream class, the data you enter are mapped into the mesh for the stream class. If any particles fall outside the limits of the mesh for the stream class, a warning will be generated. If the fractions do not add to 1 (within a tolerance) after mapping, an error will be generated.
If you select a PSD mesh for a component in the CI Solid sheet of a stream as follows:
Then this PSD mesh needs to have a lower limit higher than the upper limit of the mesh selected in the Solids | Substreams menu:

Problem Statement: Why do I get two fluid packages when importing petroleum assays created in previous versions? | Solution: When you import on a new file of Aspen HYSYS V9 a petroleum assay file (*.afam) created in a previous version, and you choose the component list when prompted (i.e. Assay Components Celsius to 1150C), you will notice that two basis are created: Basis-1 (with the component list selected) and Basis-2 (with components up to 700+). The assay is attached to Basis-2. Previous versions had components up to 700+.
This is an expected behavior for the Assay Manager in V9. When you create a new file, and import an assay, the system will detect first if you have a fluid package and a component list or not, and create a brand new one for you since you do not have one.
Then it will call AFAM file to import your old assay. Because the component list and fluid package may not be compatible with the default new fluid package V9 provided, Aspen HYSYS creates a second fluid package and component list matching the imported assay.
If later you want to modify the Fluid Package associated to an assay, you can do it directly from Petroleum Assay folder. You can find more information about this in article number 000044632.

Problem Statement: Wax deposition is one of the many flow assurance challenges to the oil production. Wax is common in the crude oil produced around the world. Wax can precipitate and deposit on pipe walls, causing higher pressure drop. Untreated wax deposition may lead to reduced flow, blockage, or loss of production. Underestimation of wax deposition can result in stuck pig while overestimation of wax deposition can result in higher frequency of pigging. More accurate prediction of wax deposition can help to reduce OPEX. | Solution: Using the Aspen HYSYS to:
Model the pipeline pressure drop
Identify the wax deposition thickness and rate
Evaluate the appropriate timing for pigging operation
You will learn to:
Leverage Wax Deposition tool in Aspen HYSYS
Tune the wax model using field or lab measurements
Monitor the wax deposition thickness over a specified timeframe

Problem Statement: When sizing a valve, I get a warning message “Unable to size the valve… Flow rate through valve is excessively high for the pressure drop” | Solution: When you add a pipe with a valve and calculate the size with the given total pressure drop for the valve and the pipe included in the valve, the sizing will take the pipe into account. The size (Cg) will increase as you increase the length of the pipe. The sizing algorithm calculates a Cg with the given pressure drop and flow rate. A warning warning message is generated in the trace window when the pressure drop in the pipe is high. As Aspen HYSYS does not perform any post calculations to include the impact of pressure drop in the pipe, this message does not have any significance and ca be ignored. This message will be removed in the future version.

Problem Statement: Define Availability, Maintainability, Operability and Deliverability in AFR. | Solution: Availability is defined as the total time a system is in an operative state. The total time in the operative state (Uptime) is the sum of the time spent in active use.
Availability = Uptime / (Uptime + Downtime)
Downtime consists of active repair time, preventive maintenance time, administrative time and logistics time.
Maintainability is the measure of the ability of an item to be retained in or restored to specified conditions when maintenance is performed by personnel having specified skill levels, using prescribed procedures, and resources, at each level of maintenance and repair.
Operability is associated with the Operating business rules, inventory management, raw material constraints, product sales constraints, etc.
Deliverability is defined as the efficiency of a system to deliver product.
Deliverability = Achieved Throughput / Required Throughput

Problem Statement: I am getting the following error when I try to open the flow diagram in Visio:
"Error during data import. When Visio opens, save the Flow Diagram and exit Visio. If errors continue then contact Vendor with this error message in its entirety. 3021"
When I open and save the Visio file as the error recommends, I get the following error | Solution: This issue is observed when you use a Main Layer FFD pipe inside a Unit Diagram. To fix it, delete all unit diagram module connections from each unit. Note that the pipes can also be resized to look like connectors so it is better to delete all the connections than trying to find the odd pipe and delete it. Remember that these connections are not required for function and only serve an aesthetic purpose.
For example, delete all the connectors as shown in the following diagram:

Problem Statement: In V8.8 and below, Aspen Plus included two types of stream reports – Default and Custom. Each option had certain strengths and weaknesses but neither was a complete solution. In V9 and above, these reports have been replaced with a new, unified stream report that is easier to use, more flexible, faster, and better integrated with Aspen Plus. The new stream reports are customizable, either by changing the Stream Summary General Options in the Home ribbon, or selecting <add properties> from the bottom of the stream report list.
However, users may want to be able to create stream summaries identical to those created in older versions of Aspen Plus. This article provides a quick solution to achieve this. | Solution: For a quick solution to creating a stream report identical to the old version's types please find attached to this article a template file which can be imported to Aspen Plus V9 and above. The attached stream results template file (FULL_V8.8_AT.apsst) will create a stream summary identical to the "Full" template in V8.8 when you import it into new versions.
To import the template file into versions V9 and above follow these steps:
1. Navigate to the stream results
2. In the Stream Summary ribbon, click the little arrow on the right of Template and a Manage Template window should open
3. Click Import to import the .apsst file attached to this article
See below (and attached) screenshots from an example file showing that the stream tables are the same in V8.8 and in V9. The only difference is that the total flow is reported twice, but that shouldn't affect any comparisons.

Problem Statement: What is the difference between the two Pressure Flow Model methods for a Relief Valve in Aspen HYSYS V9.0? | Solution: The Pressure Flow Model group in the relief valve has two models: Cp/Cv and HEM.Â
Both Cp/Cv and HEM models derive from the same first principles equation i.e the isentropic nozzle equation. The difference between the two is that the Cp/Cv method has an additional assumption for the ideal gas (i.e. pv^k = const, K = Cp/Cv) which will get an analytically close solution for mass flow rate and the HEM method solves the problem numerically with rigorous estimation of properties from Flash calculations. Â
So in case of vapor only flow both methods will give you same answer. For a 2-phase system, the HEM method estimates the properties of the fluid based on homogeneous mixture assumption between liquid and gas. It can handle situations like flashing in orifices.

Problem Statement: If an APC application loses connection to the license server, the below error message will be issued.
Unspecified Error: Server: "XXXX (default,SLM)" returned error: "5. Network license server is not running on the specified machine"
APC controllers (v8.4 or later) will continue ot run through the grace period of 10 days.
APC controllers (in v8.0 or earlier), IQ and Composite applications may not run after one hours. | Solution: In V8.0 and earlier, APC applications (controller, IQ, and composite) reacquires a license every hour. If the hourly license checkout fails due to the network error or an unresponsive license server, the application will continue to try to access the server, causing it to skip the rest of the cycle. As a result, the missed cycle messages would begin to appear and the applications appears to be stuck. In some instances, the applications may crash due to a timeout. In order to fix the problem, communication needs to be re-established between the online server and the license manager.
In V8.4 or later, a separate thread is created every controller cycle to check for licenses thus the controller now can run through the grace period on the loss of connection to the license server as well as expired license or loss of tokens.
Currently, there is no plan to change the way APC applications acquire license in V8.0. An upgrade to V8.4 is required for this additional functionality.
The IQ and Composite applications did not get this upgrade so it will have the same behavior as before. This is in consideration to be addressed in future release.

Problem Statement: Why I’m getting inaccurate results in ‘Azeotrope Search’ option for some binary pairs? | Solution: For simulation studies, it is necessary to do properties analysis before you are going to build the flowsheet. You need to check the availability of parameters, non-ideal behavior of components for various operating conditions along with selected thermodynamic model and validate the results.
In Aspen Plus simulation environment you can able to get azeotrope report for your selected component. Sometimes you will get inaccurate azeotropic report for your selected components. This is happening due to valid phases option, by default it is “Vapor-Liquid” but user need to manually change the phases.
For example, Toluene-Water it will give azeotropic temperature as 66.70 degC & type as Homogeneous.
Generally, Toluene-Water will create two liquid phases as they are immiscible with each other. To avoid such circumstances user need to change the valid phases to “Vapor-Liquid-Liquid” in input.

General Alpha function for PENG-ROB and RK-SOAVE.
But in very high temperature like T > 2Tr, alpha function is increasing.
Which means that despite the distance between molecule increases, attractive function is getting stronger. So it is physically not right.
So another alpha function like BM (Boston Mathias) or TWU are suggested to overcome this phenomena.
If the parameter is well fitted, TWU alpha function is known as the best reliability.

Problem Statement: How do you create a heating or cooling curve for a fluid that contains two liquid phases? | Solution: A number of Aspen Plus unit operations allow for the creating of an optional heating curve. If the option is available, there will be a folder for the Block called HCurves. To predict two liquid phases, a vapor-liquid-liquid, vapor-liquid-freewater, or a vapor-liquid-dirtywater flash should be used for the flash calculations in the block.
To generate a heating or cooling curve:
Select the HCurve folder in the Block.
Create a New curve and give it a number.
On the Setup tab, identify the independent variable (Heat duty, Temperature, or Vapor fraction)
On the Additional Properties tab, Identify the Property Sets to be calculated. The New button can be used to create more property sets. For a 3-phase system, "1st Liquid" and "2nd Liquid" can be selected for the phases on the Qualifiers sheet of the prop-set in addition to or instead of "Liquid". Many templates include property sets that are frequently used for Heat Curves such as HXDESIGN and HXDSGN2. The HXDSGN2 Property Set is the same as HXDESIGN except that it includes "1st Liquid" and "2nd Liquid" qualifiers instead of "Liquid".
The HCurve results may be presented using the plotting functions in the Plot section of the Home ribbon.

Problem Statement: How do I set up a Sensitivity Analysis tool in Aspen Plus EO | Solution: Solution 131058-2 How do I use Sensitivity Analysis tool in Aspen Plus EO mode similar as in Sequential Modular SM? has a procedure to run several EO cases automatically in a similar fashion as in SM mode using a script.
Here you can find an example to modify the script and run several different iterations of the case study, all the while starting from the base case. To start from the base case, base case results are exported to the base.var variable file. For each run, the base.var file is read in by the script to reset the model to the base case before performing the sensitivity analysis.
The snapshot below shows the command, inside the script, used to reset model to base case conditions:
Included are scripts is used to solve various permutations of EO sensitivity analysis cases and tabulate the results in a text files. In the model there are two Independent variables and two dependent variables included in the Anaylsis.
Column Feed Temperature and Ethylene in Column Bottoms Product are both Independent while Column Distillate Mass Flow and Reboiler Duty are dependent variables in this study.
In the first study, Temperature is changed while Mole Fraction of Ethylene is kept fixed,and then vice versa to create a Nested analysis for two steps of Temperature changes and five of Mole Fraction.The results are written to Sens.txt file.
In the second study both Temperature and Mole Fraction of Ethylene are changed simultaneously in each step of Ethylene Mole Fraction and then Ethylene Mole Fraction is reset while Temperature is not.
To run the first case study, invoke the Sens.ebs file and for the second study Sens2.ebs.
To begin the analysis, load the BKP file into the Aspen Plus Graphical User Interface, solve the simulation in SM mode, switch to EO in Simulation mode and invoke the script by typing INVOKE SENS or INVOKE SENS2 at the command line. The script will drive the problem through a series of Simulation solutions and write the results to the text files of the same name as the case study. The case studies can be invoked several times because for each run, the model is reset to base case conditions by the script.
Starting values of Temperature and Mole Fraction can be manually from the Base.var file, the variables to be changed are shown below:
Values can also be changed from within Aspen Plus Graphical User Interface.
The number of cases or steps run in each study can be changed by changing the following values in the script:
The step size for each Independent variable can also be adjusted by changing the following values in the script:

Problem Statement: What is the Recycle Efficiency value used in BLOWDOWN utility in Aspen HYSYS? | Solution: There is no recycle efficiency concept in BLOWDOWN.
BLOWDOWN has a liquid HC and vapour HC "zone". Within this zone, the heat transfer and mass balance are rigorously determined for each zone. The two phases are not required to be in equilibrium.
In the Depressuring Utility, the Recycle Efficiencies set how much of each phase is involved in the flash calculation. This is a concept in HYSYS to imposes equilibrium assumptions.

Problem Statement: How to troubleshoot Aspen Properties Database (APED) connection issues.
Description: When running a product that uses Aspen Properties, such as HYSYS, Aspen Plus, and Exchange Design and Rating, you may receive an error that the databases failed to initialize. This happens when the connection from the Aspen application to Aspen Properties is lost. This solution will assist you with troubleshooting the error and re-establishing the connection. | Solution: The link issue is associated with the installation of Aspen Properties and the SQL Server engine.
Due to different security settings on different machines, the installation is not uniform and the user will get the above error message.
The following guidelines will help troubleshoot the linkage issue with Aspen Properties and registering the Aspen Properties databases.
In the Control Panel | Add Remove Programs make sure that Microsoft SQL Server 2008 or 2012 and its components are installed.
Make sure that the Aspen Properties Enterprise Databanks option is selected by going to Start | All Programs | AspenTech | Process Modeling V8.x | Aspen Properties | Database Selector – Aspen Properties V8.x.
Run the Aspen Properties Database Configuration Tester from Start | Programs | AspenTech | Process Modeling V8.x | Aspen Properties | Database Tester - Aspen Properties V8.x to identify any issues.
The databases can be restored through the Aspen Properties Database Configuration Tester by clicking the Restore databases directly button.
If the Installation of SQL Server and Aspen Properties goes as expected, the configuration tester results will be as shown in the screenshot below.
Here is a description of each of the items that the Database Configuration Tester checks:
License Availability: The tester will check the license availability for Aspen Properties. It will state that the license is either available or that it is not available. If the license is not available, then there is an issue with the license.
Configuration File: The tester verifies that the configuration file (config.aem) was installed with the correct permissions. If the config.aem file is not available, then you will get a status of Configuration file is missing. If the config.aem file does not have the appropriate modify permissions, the tester will display a message stating so.
SQL Engine Authentication Settings: It will report all servers that have at least one Aspen Properties database registered on the computer. The Authentication Mode must be set to SQL Server and Windows (Mix Mode), and if it was set correctly then the status will show OK. Otherwise, a message will appear stating that Mix Mode needs to be set. If there is an issue with the SQL Server, a message will appear in the Status column describing the issue.
Database Access Settings: It attempts to access each registered database and performs three tests.
It verifies that it can connect to the database. The result will either be a Connection Successful message or a message indicating the error that occurred.
It attempts to read the database as Aspen Properties would. This should report Granted/Successful if the database is configured for access from these programs or Denied/Failed if the database is not configured correctly.
It attempts to read the database as the Database Manager would. This should also report Granted/Successful or Denied/Failed based on the security options.If all the connections are appropriate, then the status will be as shown above in the screenshot. If it cannot access the databases or cannot find them, then an error saying Login Failed or Exception has thrown will appear.
The following steps will assistance you with diagnosing issues from the Database Configuration Tester:
Make sure the SQL Server 20xx (2008 or 2012) is running and the appropriate protocols are enabled.
Go to Start | Programs | Microsoft SQL Server 20xx | Configuration Tools | SQL Server Configuration Manager.
In the left side pane, check if the SQL Server 20xx Services (ie: SQLEXPRESS) is running.
If not, in the right side panel, right-click on the SQL Server service (ie: SQL Server (SQLEXPRESS)) and select Properties from the context menu.
In the SQL Server Properties window, click the Start button. (Note: The Log on as has to be set to Built-in account: Local System, as shown below.)
In the left side panel, expand both SQL Server 20xx Network Configuration and SQL Native Client Configuration.
Under SQL Server Network Configuration, highlight Protocols for <the name of the SQL Service> (ie: SQLEXPRESS) and Enable the first three protocols shown below.
To enable them, right-click the protocol and select Enable from the context menu.
After Enabling the protocols, Restart the SQL Server (ie: SQLEXPRESS) using Stop and Start or Restart options.
Once this is done, run the Aspen Properties Database Configuration Tester again and check if the issues have been fixed.
If the tester fails at Step 3 - SQL Engine Authentication Settings, then SQL Server and Windows (Mix Mode) is not set. The tester will display a message asking to turn Mix Mode on. If not, it needs to be turned on manually. The easiest way is to use SQL Server Management Studio 2008 or 2012, which is not installed by default.
Go to Microsoft.com and download the SQL Server Management Studio 2008 or 2012 (NOTE: Download the version that matches your SQL Server).
Install SQL Server Management Studio.
Follow these steps:
Go to Start | All Programs | Microsoft SQL Server 20xx | SQL Server Management Studio.
The Connect to Server window will display. Select the Server Name and Windows Authentication. Click Connect.iii.The Microsoft SQL Server Management Studio window will display. In the tree on the left,
right-click the name of the server and select Properties.
iv.The Server Properties dialog box will display. At the left, click Security.
v. Under Server authentication, select SQL Server and Windows Authentication mode, and
click OK.
After this change, run the Aspen Properties Database Configuration Tester again and check if the issue is fixed.
If the configuration files or database definition files (*.LDF and *.MDF) are missing at the APED folder on the computer’s local drive (Note: The APED folder location is different between aspenONE versions) or fails at the Database Access Settings (Step 4), then the databases have to be manually restored with the appropriate login name and password.
APED Folder Location:
V7.3.2 – V8.x: C:\Program Data\ AspenTech\APED Vx.x (V7.3.2 or V8.x).
V7.0-V7.3: C:\Program Files or Program Files (x86)\ AspenTech\APrSystem V7.X\PropertiesDatabase\Database
To restore the database(s) manually, go to Start | All Programs | AspenTech | Process Modeling V8.x | Aspen Properties | Database Manager - Aspen Properties V8.x. Click OK on the warning message and the Aspen Properties Database Manager will open.
In the Aspen Properties Database Manager, on the left side, right-click on Aspen Physical Properties Databases and go to All Tasks | Restore Database.
At the Restore Database Wizard, fill in the following information:
Uncheck Use LocalDB if you have SQL Server installed.
Server Name: <SQL Server Service Path> (Example: Server1\SQLEXPRESS)
Authentication Mode: SQL
Login Name: apeduser2 (v7.3.2 – V8.x) or apeduser (v7.0-7.3)
Password: Aproperty88# (v7.3.2 – V8.x) or Aprop100 (v7.0-7.3)
Database Name: <NISTV8x, FACTV8x, APV8x, or APEOSV8.x (V8.8 and higher)> or <NISTV7x, FACTV7x, or APV7x>
Click Browse.
Go to the APED folder on the computer’s local drive and select the *.LDF file that corresponds with the Database Name entered. Click Open.
Click OK.
Repeat the restoration for the other databases if necessary.
Run the Aspen Properties Database Configuration Tester again and check if the issue is fixed.
In some instances only the database registration will be missing. The configuration file and the database definitions files have been created and available, but they were not registered. This may happen due to a login failure because of an incorrect user name or password while installing the Aspen Properties. Usually the installation will set this up correctly, but if your company has certain password requirements, this may cause the issue. In those instances, the database(s) will need to be registered through the Aspen Properties Database Manager.
In the Aspen Properties Database Manager window, on the left side, right-click on Database Manager – Aspen Properties V8.x and select Register a Database.
In the Registered Properties Databases window, enter the same information that was done on the Restoring the Database Step. (NOTE: uncheck Use LocalDB if SQL Server is installed)
Once the Login Name and Password has been entered, select the Database box and the available databases will appear. Select a database from the Database list and click OK. (Hold the SHIFT key to select multiple databases at once.)
Run the Aspen Properties Database Configuration Tester again and check if the issue is fixed. Once it is fixed, the user can open the HYSYS, AspenPlus or EDR applications and connect them to the Aspen Properties without any issues. This is a one-time process and will need to be performed if the issue mentioned in the problem statement appears.

Problem Statement: This Knowledge Base article provides steps to resolve the following issue:
Daily scan of All Files and Tags returns zero tags when AFW Security is in place. | Solution: The request to scan data must be made under a user’s context who has privileges to read the data. In aspenONE Search V8.5.5 and 8.7, the Dispatch Service makes a call to the aspenONE Scheduler when Start Scan is clicked on the All Tab to invoke Scan All Data, but the aspenONE Scheduler doesn’t invoke the scan under a user’s context that has privileges to read the data to be scanned. To use this feature, the identity for the Dispatch Service Application Pool should be set to the same identity as used by the AspenProcessDataAppPoolx64 Application Pool.
To summarize, the Dispatch Service Application Pool must have the same identity as the AspenProcessDataAppPoolx64 Application Pool when AFW Security is in place to support:
· User clicking the Start Scan button on the Search Admin UI All tab
· Scheduled daily scans on the All tab
· Scheduled daily scans on the Files tab
Note, the Dispatch Service was removed in v9.0 of Aspen Web Server.

for example:
"my report" contains an image in the report, so mht file is generated.
"my report1" does not contain any image in the report, so html file is generated.

Problem Statement: If moving an Aspen CIM-IO server to another domain, what configuration changes, if any, need to be made? For example, suppose the Aspen Cim-IO server will be moved from a business LAN to the process LAN. | Solution: If the name of the Aspen Cim-IO server will remain the same after moving from the business LAN to the new process LAN, there should be no configuration changes needed. If the name of the Aspen Cim-IO server does change the cimio_logical_devices.def file the IP.21 server will need to be modified to reflect the new nodename of the CIM-IO server. It's also possible the interface configuration in the Cim-Io Interface Manager will need to be changed to reflect the name change.

Problem Statement: CIM-IO provides a way to convert values coming from OPC/DCS/PLC source before this can be actually written into IP.21 database, this can be done through the use of IoEuConvDef records. This solution gives example on how to use these records to filter values that could be above or below specific limits before they reach Aspen InfoPlus.21 database. | Solution: CIM-IO user guide on (Chapter 8 The Cim-IO Engineering Units Conversion Record) gives the formula by which conversion is done using parameters defined on a IoEuConveDef record:
This formula is just a linear conversion between values and conditions for upper and lower limits are also included. Since this is just a liner conversion, setting rangehi = maxcount and rangelo = mincount (please check any of the previous references or CIM-IO user guide to be familiar with these concepts) then the conversion will return always the same value and we will be using just the limit conditions to work for filtering values. Here’s an example on how to set this up:
Having a value from OPC like
Which represent a random integer values from 0 up to 150, we want to apply a filter to only get values between 20 and 60. For it we need to add an occurrence on the Io-Eu-Conv record as follow:
Here the Lim20-60 entry is a custom entry in which IO_MAX_COUNTS = IO_RANGE_HI = 60 (our upper limit) while IO_MIN_COUNTS = IO_RANGE_LO = 20 (our low limit). Now we need to set this on the tag record:
Here the IO_DATA_CONVERSION value of the tag has been changed to select the custom entry we create previously. In this point there is no need to set IO_Data_Processing off since this will start to work at the moment getting just values between 20 and 60:
Consider that values that overpass low or upper limit will pass (and probably saved by historian) with the limit value; there is no way for this data to not be written into IP.21 just by this method. Compression algorithm should be properly set to prevent this method to writes constant limits values when the tag behavior is constantly above or below limits.

Problem Statement: What is the purpose of the Aspen Cim-IO configuration utilities? | Solution: AspenTech introduced two configuration utilities for Aspen Cim-IO that incorporate functions previously found in a variety of Aspen Cim-IO configuration methods.
The Cim-IO Interface Manager is run on the Cim-IO interface system and used to configure the interface. The manager contains templates for all the supported interfaces. It also includes the ability to set arguments previously found in Cim-IO Properties, and OPC Properties.
The Cim-IO IP21 Connection Manager is run on the Aspen InfoPlus.21 server and used to configure a connection to the interface. The manager establishs a connection to the interface and create the required records and tasks in Aspen InfoPlus.21. It includes the ability to set arguments previously found in Cim-IO Properties.
Configuration instructions are found in the Aspen Cim-IO Users guide(s) in the Cim-IO Interface Manager and Cim-IO IP21 Connection Manager chapters. Additional details on Interface specific configurations are found in the Cim-IO Interface specific Users Guides. The Help button in each utility provides additional usage details and interface specific settings.

Problem Statement: Can anti-virus software such be run on a server running Aspen Cim-IO? | Solution: Aspen Cim-IO files including list files, store queues, and log files should be excluded from virus scanning.
Aspentech recommends excluding the Program Files (x86)Aspentech\Cim-IO, and ProgramData\Aspentech\Cim-IO folders from virus scanning. In addition to any custom Store Queue folders that are defined.
The reason for bypassing virus-checking on these files is because anti-virus software checks files that "change" for potential viruses. System performance can be degraded with continual scan checks of files that may update frequently.

Problem Statement: Gas-Oil Ratio (GOR) HYSYS Extension for the Characterization of Reservoir Fluids
Note: Works in version 2006.5 and above | Solution: Gas-Oil Ratio (GOR) Aspen HYSYS Extension is a useful unit operation to characterize a reservoir fluid. It provides an alternative to using either PVT analysis tools or the use of black oils to characterize reservoir streams that contains a mixture of oil, gas and water.
It can be used in one of two ways:
1. Calculates the Gas-Oil Ratio (GOR) of a feed fluid with a defined composition
2. Adjusts the gas, oil, and water flows to make the resultant product stream respect the specifications for GOR, water cut and oil flow
How the GOR Extension Works?
If no GOR or water cut targets are given, the unit operation will only report the GOR and water cut. For a single hydrocarbon feed stream you will have to provide the oil flow target to make the unit operation calculate.
If separate gas, oil and water streams are provided, it will adjust the flows of each feed to obtain a product stream with the desired specifications. If a single hydrocarbon feed stream is provided, the unit op will flash this stream internally at standard conditions and use the obtained vapor, oil and water flows as starting points for getting the targets.
The GOR and water cut can be calculated for a single stage or you can ask for a multi stage calculation. You need to provide the flash conditions if more than one stage is requested. For a single stage flash, a default of standard conditions is used.
Note
1. The GOR is calculated using the oil and water actual volume flows at the specified stage conditions. Vapour flow is always the standard gas flow.
2. The oil density at the last stage can also be tuned to a specified value. The solution may take a couple of seconds if you require tuning of the oil density. Note - The method used is not supported by most extensions and hence, if you pass the oil stream through an extension, the density tuning will be lost.
3. It does the material balance accurately. It does not account for enthalpy balance. The user feeds the streams at conditions and the outlet condition is set to what is entered in Well
Keywords: GOR, Extension, Upstream
References: Condition's. So, you would not normally have an enthalpy balance.
Example HYSYS Case
Two sample HYSYS cases (GOR AND Wellhead curves.HSC and GOR AND Wellhead curves_EQ.HSC) are attached for download illustrating the use of the GOR Extension. |
Problem Statement: How does Aspen HYSYS obtains the values of the Heat of Combustion for hypo components? | Solution: Different from pure components, the heat of combustion values for hypo components cannot be retrieved from a database, since their properties are usually obtained from distillation data.
Aspen HYSYS currently does not estimate the heat of combustion for hypo components that are defined by the user or generated through Oil Manager, therefore, if these values are required in the simulation, the user will need to manually enter them.
To enter these values, the user can follow the procedure described in Article 44523. In this case, an empty value for the Heat of combustion will appear, so the user needs to enter the corresponding value.

Problem Statement: How to customize the original SYS.ILB delivered with Aspen Plus to include customized INSERT files.
Found in versions 9 and above. | Solution: The procedure to update sys.ilb (delivered in the .....AP100/xeq directory) is to use MAKEINS to rebuild it in a working directory with the Aspen Plus inserts (delivered as self-extracting executable extr_ins.exe in AP100/xeq or update directory) plus any additional insert files from the customer.
Run the self extractable file extr_ins.exe. (In Windows just double click on the .exe file through Explorer). It will explode to create the Aspen Plus insert files (should be in the update directory). Copy these files over to a working directory, and add the new insert files to this directory. Run MAKEINS. The inserts will be compiled into a file called USER.ILB. Rename the same to SYS.ILB and replace the original SYS.ILB with it.

Problem Statement: Flue gas after the furnace or reactor often has a high temperature and the gas is cooled down its temperature by quenching cold water.
Temperature control of quench tower is important. If the temperature is not cooled enough, this gas will impact next process.
For example, the purpose of quench tower in tail gas clean up process is to prevent performance degradation of next process, otherwise, toxic amount of Hydro-sulfide gas can emit to the atmosphere if it is not treated well.
This example case shows how to set outlet temperature of quench tower by controlling quench water flow rate by using 'Adjust Block'. | Solution: First, gas stream is fed into the column's bottom stage and this gas is saturated with water.
Water saturation can be done by 'Water Saturation' Block.
30 ℃ of Quench water is fed into top stage of the column and it is cooling hot gas by direct contact.
Second, heated quench water then is running out of the column as bottom product. QWR (Quench-Water-Return) flow is split into main flow and purge flow to maintain the total flow rate of quench water. This flow is then pressurized and cooled to cold quench water again then return to the column.
Third, Set the temperature of cooled gas as target variable, and adjust flow rate of quench water stream right after the 'Split' block.
Please set boundary condition carefully, it will help the convergence of the simulation.

Problem Statement: HYSYS Stream Reporter (HSR) Version 1.63 | Solution: The latest version of HSR is Version 1.63. Last updated July 27th, 2016.
HYSYS Stream Reporter (HSR) is an Excel spreadsheet utility that allows material stream conditions, properties and compositions to be easily reported onto a spreadsheet, it also enables streams in different cases to be conveniently compared.
HSR can report properties from the following phases: Overall, Vapour, Light and Heavy (Aqueous) Liquid, Combined Liquid and Solid. It also allows stream user variables and property correlations to be reported. It is also possible to create formulae in the output table. The user can save sets of properties or use one of the pre-built property sets. Streams from different HYSYS cases can be reported in the same stream table. Once a stream table has been generated it can be updated by pressing a single button. Stream tables can be moved to another Excel workbook whilst maintaining the ability to be updated.
HSR takes the form of an Excel spreadsheet file with embedded Visual Basic for Applications (VBA) code that demonstrates how HYSYS can be accessed programmatically. The VBA source code is freely accessible and users are encouraged to learn from it and adapt it to their own needs.
