Problem Statement: How to convert equilibrium stages to actual trays for distillation column (Design) before performing Column Analysis? | Solution: Distillation column internal hydraulic calculation must be carried out to real trays instead of equilibrium stage as equilibrium assumption is never satisfied. (like transfer rates limitation, foaming, entrainment, etc.) These uncertainties are accounted through efficiency, which accounts for the departure from equilibrium stage (Ideal stage).
Radfrac model supports three types of efficiency:
Overall Efficiency
Vaporization Efficiency
Murphree Efficiency
The efficiencies can also be specified as
Overall
By Stage
Column Section wise
Individual component wise
Overall Efficiency:
Overall efficiency is the ratio of theoretical (ideal) stages number to actual column tray number
Very simple but least flexible approach
Just direct conversion of actual tray number to ideal stage number
Vaporization & Murphree Efficiency:
Vaporization efficiency is defined as
Murphree efficiency is defined as
Where
K is equilibrium K Value
x is liquid mole fraction
y is vapor mass fraction
Eff v is vaporization efficiency
Eff M is Murphree efficiency
i is component index
j is stage index
Vaporization efficiency alters the K values for VLE, and this may alter relative volatility of the components
Vaporization efficiency is not widely used / not better to use
Various correlations/lab data exist for Murphree efficiencies
Limitations for Murphree efficiency:
Murphree efficiencies will not work well in reactive systems because the mass transfer due to kinetic or equilibrium reactions is not related to the phase equilibrium driving force.
Murphree efficiencies can be used in apparent approach electrolyte systems where the only reactions are handled by the apparent approach
Murphree efficiencies are only meaningful on the last stage if there is an on-stage feed containing vapor entering that stage, as is typical of absorber columns.
Example conversion using Murphree efficiency concept:
Considering a distillation column for separation of 41% of C3 in the Overhead stream (achieved by varying reflux ratio) with 15 equilibrium stages (13 + 1 condenser + 1 reboiler) having its feed tray located at 8th stage and tray efficiency of 65%
Column trays = 13/0.65 = 20 + 1 (condenser) + 1 (reboiler) = 22 total stages
Feed Tray location for actual trays = [ 8 (feed stage) - 1 (condenser) ] / 13 (equilibrium stages) * 20 (actual trays after conversion) + 1 (condenser) = (8-1) / 13 * 20 + 1 = 10.8 + 1 = 11.8 ~ 12
For entering the efficiencies:
Go to Efficiency | Options sheet, select Murphree efficiencies as type and Specify stage efficiencies as the method. On the Vapor-Liquid sheet, specify the efficiency against each stage.
Note: With this input method, stages 2-21 will be set at 0.65 (interpolation for stages 3-20 between 0.65 and 0.65, or held constant)
After the addition of efficiencies and adjustment of stages to real trays, the calculated Reflux Ratio should essentially be the same. Slight differences are more likely due to rounding error on the feed stage location conversion. Now the column model is setup for hydraulic calculation based on a stage representing an actual tray within the column.
While rating the distillation column, Murphree stage efficiencies or component efficiencies can be adjusted or varied for a design specification to match the given column operating conditions if
Efficiency is not known
Actual column operating conditions are known
As an alternative to using Vaporization & Murphree efficiency with equilibrium approach, rate-based modelling option can be used for avoiding these limitations associated with efficiency approach.

Problem Statement: How to change the number format of the stream result displayed in flow sheet window? | Solution: If display of any of the pre-defined or user-defined stream result property is activated in the flow sheet window, then format of the displayed digits & its unit of measurement can be formatted based upon user requirement.
Open the Set flow sheet display option window from Flow sheet Modify window. Alternatively, you can also open from File -> Options -> Flowsheet
Default digit formatting used for predefined stream display parameters to:
Temperature, Mole/Mass/Volume Flow Rate, Heat/Work is %.0f
Pressure & Vapor Fraction is %.2f
Default format for user-defined Global stream data is %.2f
The format of these global stream data in the flow sheet can be controlled by modifying these conversion formats:
%-xx.yye
%-xx.yyf
%-xx.yyg
where E, F, G stands for Exponential, Fixed and General option respectively.
Variable
Explanation
% Percent character. Lead character for format specification.
- Optional minus sign, which left-justifies the number. Without the minus sign, the number is right-justified.
xx A digit string specifying a minimum field length for the converted number. The number takes at least this much space to print, and more if necessary.
yy A digit string specifying the precision, (that is, the number of digits) to be printed to the right of the decimal point.
e Number is converted to the form [-]a.bbbbbbbe[+]cc. Length of b is specified by yy (Default is 6). Use upper case E in the format specification for upper case E in the printed numbers.
f Number is converted to the form [-]aaa.bbbbbb. Length of b is specified by yy (Default is 6).
g The shorter of %e or %f is used. Use upper case G in the format specification for upper case E in the printed numbers.
For example:
%10.0f will display whole number without any decimal point or exponent
%10.nf will display numbers without exponents but with n digits to the right of the decimal point

Problem Statement: When testing the connection between the PI adapter and Aspen Mtell in System Manager, the user gets an error message that says ‘Detailed Error - 404.0 - Not Found'
In addition, under Application Pools the PI adapter has 0 applications.
This can happen when a second PI adapter is configured by duplicating a first adapter’s folder, configuring a new IIS user and adding a new data source in Aspen Mtell. | Solution: The Test button in System Manager tests to confirm that System Manager is able to find and load the Historian IIS page, and the 'Detailed Error - 404.0 - Not Found' error means that the page cannot be found. One of the reasons for this error message is that the web application is not fully published.
Please follow the steps below to convert the Adapter page in IIS Manager to Application:
Go to Control Panel\All Control Panel Items\Administrative Tools and double click on Internet Information Services (IIS) Manager to open IIS Manager.
Expand Sites, Default Web Site, AspenTech, Aspen Mtell and Adapter
Right click on the adapter name Pi and click Convert to Application
In the pop-up, assign the page to the appropriate Application pool
Click OK.
If above steps does not resolve Error 404, then please contact Aspen Mtell Support team by sending email to [email protected] to help resolve the issue.

Problem Statement: Why does the calculation in Aspen Calc shows -1.#IND as a result? For example, in Aspen Calc V10.1, we have a calculation using TagAverage function to calculate the tag average input value during the last 30 mins. The calculation formula is AVG=TagAverage(tag,now()-00:00:30,now(),0,0)
If there is no new input value for this tag during the last 30 mins, the calculation will show -1.#IND as a result. This only happens on Aspen Calc V10.0, V10.1, and V11.0. | Solution: The -1.#IND means that it's an indeterminate form (such as 0/0). For example, the TagAverage function is the total tag value divided by the number of values. If there's no value in the last 30 minutes, it's being divided by zero, which becomes an indeterminate form (0/0).
In Aspen Calc versions prior to V10.0, the indeterminate form shows 0 as a result. The change from 0 to -1.#IND was based on some customers' requests and was implemented as of MES V10.0.

Problem Statement: ProMV Online Deployment Failure caused by model variable name changes or incompatible variable names (Case sensitivity and Special character) | Solution: IP.21 does not count case-sensitivity or spaces as distinguishing characters in tag names; while ProMV Online does count spaces as distinguishing characters in tag names.
If the Tag name in IP21 and ProMV does not match then user will not be able to deploy the model online.
Case 1: Model variable name changes only by case sensitivity or special characters after a deployment:
For Example:
Tags Name in IP21 is MV10000007.ProMV.PX_9311/12 LOCAL EXHST DUCT TEMP#1
Variable name in ProMV is MV10000007.ProMV.PX_9311/12 LOCAL EXHST DUCT temp #1
The Tag name and variable name does not match, there is space and case sensitivity issue.
To address such issue, user should clone the model and deploy the newly cloned model with correct variable name. Delete the old model after creating the new model.
Case 2: To incompatible model variables (e.g. only different by case sensitivity or special characters, such as space or tab) exist in an offline ProMV model:
For Example:
Variable1 name in ProMV is PX_9311/12 LOCAL EXHST DUCT temp #1
Variable2 name in ProMV is PX_9311/12 LOCAL EXHST DUCT temp#1
During ProMV offline model building, there is no issue. But when trying to deploy it online, both model variables will point to a single IP.21 tag name like below and the online deploy will fail.
Tags Name in IP21 is MV10000007.ProMV.PX_9311/12 LOCAL EXHST DUCT TEMP#1
To address such issue, user has to correct the variable names in datasheet and rebuild the offline model before coming back to deploy it online.

Problem Statement: If a tag (data record) in Aspen InfoPlus.21 receives a value (perhaps a positive value indicates that a machine is running and a 0 (zero) indicates that it is not) and we want to test that value, report on it, and cause another different record to receive that value (but only if it is a positive value), how might that be coded in Aspen SQLplus? | Solution: This example uses tags defined against either IP_AnalogDef or IP_DiscreteDef. The record we read from is called 'RECSource' and the one receiving the values is called 'RECTarget'. Please substitute appropriate record names for RECSource and RECTarget when using the SQLplus code and in the QueryDef record that are relevant to your environment.
Note - the statements in green after the double dashes ( -- ) are just comments and do NOT have to be included in the record. One version with and one version without the comments is included below.
--- WITH comments ---
local yy; -- This is a local variable
yy = (select ip_input_value from RECSource); -- The variable holds the data from the source record
write 'The current time is: '||getdbtime; -- Displaying the current time
write ''; -- A blank line
write 'The value that we are measuring is: '||yy; -- Writing the value which has been retrieved
write '';
CASE -- Here we will check on the value being retrieved
when yy = 0 -- If the value is 0 then perform actions below
then write 'The machine is off.'; -- Indicate that the machine is not running
when yy > 0 -- If the value is greater than 0 then perform actions below
then write 'The machine is on.'; -- Indicate that the machine is running
update RECTarget set ip_input_value = yy; -- Update the target record with the (positive) value
end; -- The end of checking on the value (and the end of the query)
--- WITHOUT comments ---
local yy;
yy = (select ip_input_value from RECSource);
write 'The current time is: '||getdbtime;
write '';
write 'The value that we are measuring is: '||yy;
write '';
CASE
when yy = 0
then write 'The machine is off.';
when yy > 0
then write 'The machine is on.';
update RECTarget set ip_input_value = yy;
end;
Enter the code above in the Aspen SQLplus Query Writer and save it as a QueryDef record. Once it is saved then expand the #WAIT_FOR_COS_FIELDS repeat area in that record to be 1 and set the following values:
WAIT_FOR_COS_FIELD = RECSource IP_INPUT_VALUE
COS_RECOGNITION = all
SET_OPTION = none
The above actions will cause the SQLplus code to be run any time there is a new value in the IP_INPUT_VALUE field of the RECSource record.
Here are some examples of what the output would look like:
The current time is: 20-JAN-20 18:24:42.8
The value that we are measuring is: 0
The machine is off.
The current time is: 20-JAN-20 18:28:18.2
The value that we are measuring is: 1
The machine is on.

Problem Statement: Why do I sometimes get the message that the molecular weight (MW) for a component is different than the molecular weight calculated from the formula? Which one is used?
The message is similar to the following:
MW AVAILABLE FOR COMPONENT GE IS DIFFERENT FROM MW CALCULATED
FROM FORMULA (ATOMNO/NOATOM). CALCULATED VALUE IS USED.
AVAILABLE MW = 72.64000 CALCULATED MW = 72.61000 | Solution: By default, the molecular weight.is calculated from the atomic formula. Molecular weight is available in all Aspen Properties databanks. However, the databank MW value may not contain enough significant figures for certain applications for which atomic balance is important, such as reactor modeling. Calculating the molecular weight from the atomic formula makes the molecular weights consistent for all reactions. The calculated MW is more accurate than the databank MW.
Do not use this option with components like HE-3 which represent specific isotopes.
If you do not want Aspen Properties to calculate the molecular weight but instead use databank values, then clear the Calculate Component Molecular Weight From Atomic Formula check box.
The atomic mass of the atoms can be found in Knowledgebase document 95561.

Problem Statement: I am trying to write a Fortran subroutine that can write to the control panel, history file and report file. I am following procedures outlined on Aspen Plus User Models manual, but code does not work as expected. | Solution: In a user written subroutine, the unit number for the history file and the report file are defined in PPEXEC_USER as USER_NHSTRY and USER_NRPT respectively. To redirect the output of a WRITE statement in a Fortran subroutine to the Control Panel, the Common variables for these output streams must be included in the subroutine code and compiled further (SeeSolution ID105408). To include these variables, make sure that the following line is in the subroutine:
#include ppexec_user.cmn?
Note that this command starts in the first column on the Fortran Code.
For example:
#include ppexec_user.cmn?ᾉ
WRITE(USER_NRPT, *) X, Y, Z
WRITE(USER_NHSTRY,*) X, Y, Z
RETURN
END
Although USER_NTRMNL is retained as a legacy from input language runs (writing to the terminal), it cannot be used to write information to the Control Panel for runs within the GUI. Instead, use the DMS_WRTTRM utility. You must include the following code beginning in column 1:
#include dms_maxwrt.cmn
Next, use a Fortran internal write to MAXWRT-MAXBUF and then call the utility DMS-WRTTRM, with the number of lines to be written as the argument (Refer to Chapter 4 of Aspen Plus User Models manual for further references).
For example,
#include dms_maxwrt.cmn?
WRITE (MAXWRT_MAXBUF, *) X
CALL DMS_WRTTRM(1)
RETURN
END
The attached Aspen Plus model and user subroutine, were taken fromSolution ID 121539.
Fortran code was added to user subroutine to make it able to write to control panel, History file and report file.

The draw stream's enthalpy is calculated by the column subflowsheet and the pumparound. The difference that exists is not acceptable by the flash tolerance. The difference came through the gap of heat / spec tolerance of the column. The difference is small but was enough to cause the error. It can be resolved by either one or a combination of the following actions:
1. Tighten the Heat / Spec Error Tolerance. The option is under Parameters | Solver. The default value of 5e-4 should be reduced to 1e-4 or lower. Please note that tightening the tolerance may require additional iterations for the column to converge.
2. Close the error message. Turn the solver on (click the green traffic light button in toolbar). You may have to repeat this step several times until the column converges.

Problem Statement: The following message will be displayed when using an older version of DMCplus Build to open a CCF file that was saved using a newer version of DMCplus Build:
The CCF file being loaded was last edited with a NEWER version of DMCplus Build (13.0). You are currently using DMCplus version 12.0. Saving could cause undesirable results. | Solution: DMCplus Build does not allow backward compatibility when opening CCF files generated using a newer version of the software. While the older software can still open a CCF file generated in a newer version of the software, a warning message is used to notify the user of possible changes in the controller parameters from one version to the next. We check to see whether the latest software can open the earlier CCF, but not the other way around. This is common commercial software practice.
This warning is essentially telling you that the new features in the new version will be lost in the old environment you are trying to open it in. Any new parameters that were added in the new version will remain in the CCF file but they will just not be functional. For example, the Calibrate feature is included in V11 but not in V9. So CALIBOPT, the new tuning parameter added in V11, may still show up in the CCF that was created in V11 and opened in V9, but it is not expected to work in a V9 environment.
To be sure that you are not deleting any of the new parameters by opening the CCF file in an older version of the software, use the Save As option to save the file with a separate name and then compare the CCF files. Any commonly used high end text editor software like Word or Notepad++ can be used to perform this comparison. Another way to do this is to use the attached Excel Template. Copy the CCF text into the respective columns to break it down line by line and note the differences. There might be the same parameters in a different order or version number.
Note: There is no difference in the CCF files generated using DMCplus Build V7.3 and V8.0.

Problem Statement: HTRI is unable to link to Aspen HYSYS. Is there any investigation that can be performed from AspenTech's side on this issue? | Solution: HTRI links to HYSYS using COM/OLE, which is similar to how Aspen Simulation Workbook and other automation tools interact with HYSYS. If HTRI fails to link to HYSYS, the only investigation that AspenTech support can perform is to ensure that the HYSYS automation type library is correctly registered and working.
The attached Excel utility can be used to check if the HYSYS automation library is working. To use this utility:
1. Enter your HYSYS version in Cell B2. It should be in the format V.#.# (e.g. V9.0)
2. Click the Test HYSYS button.
If the test passes, the following message box will appear:
If at any time the Excel utility shows as passing, the issue is not on AspenTech's side and should be directed to HTRI.
If the test fails, the following message will appear instead:
Note that the test fail message will also appear if you entered an invalid or nonexistent version of HYSYS in Cell B2.
If the test fails, you can rectify the issue by going to the Start Menu, navigating to the folder containing the Aspen HYSYS shortcuts, and running the Set Version - Aspen HYSYS utility corresponding to the version in question.
Make sure to right-click and Run as Administrator. Administrator rights are required to run this utility.
You will get the following message box upon completion if the Set Version utility successfully runs:
If the Excel utility still shows as failing after running the Set Version utility, please contact AspenTech support for further investigation.

Problem Statement: How to reset analyzer drift correction. | Solution: There is no good way to reset the analyzer drift value. However, here are a couple of suggestions:
Set the AZUDRIFTFRAC to 1 and enter a random lab value that matches exactly with the analyzer. Once the drift is reset to zero you can set AZUDRIFTFRAC back to its original value. Note that this will impact the lab bias, but if you believe the analyzer then it should be OK.
Unload the app and reload it with an IQF file that has zero for ANZRDRFT. This should also reset it.

Problem Statement: This Knowledge Base article provides guidance on how the different Windows file permission levels affect security of aspenONE Process Explorer plots and graphics. | Solution: Modifying plots and graphics
1. Modifying graphics is not a concern because there is no way to modify graphics in aspenONE Process Explorer (a1PE is just a viewer). In fact there is not even a Save option for graphics.
2. If a user only has READ permission to a plot or graphic file, then they will still be able to fully interact with the plot or graphic in aspenONE Process Explorer (a1PE) such as adding/removing tags, exporting data to Excel, changing pen properties, using the timeline, etc.. But since they only have READ permission, they will not be able to save the file so any changes they make will not be saved.
Exporting tag data to Excel
There is one separate permissions requirement for being able to export data to Excel: in addition to having READ permission to a plot or graphic file users must also have WRITE permission to the Export folder under C:\inetpub\wwwroot\AspenTech\ProcessExplorer\WebControls
The Export folder is where the CSV file is downloaded into.
Inserting tag values into the database
If within a graphic there is the ability to insert tag values, you can restrict that action using AFW. That is what the Standard Write securable object is for.
Restricting users' ability to delete, move and rename existing files and folders in the Navigation pane
Prior MES V9.0:
Within a1PE users can delete, move (cut and paste), and rename existing files and folders by opening up the Navigation Menu Tree and right clicking on the item. Restrict users from being able to do this by not giving them the Modify permission to that folder or file.
aspenONE Process Explorer plots and graphics are saved in the following directory on the web server:
Public – C:\inetpub\wwwroot\AspenTech\ProcessExplorer\Files\Public
Private – C:\inetpub\wwwroot\AspenTech\ProcessExplorer\Files\Private\<username>
After MES V9.0:
aspenONE Process Explorer plots and graphics are now saved in the following directory on the web server:
Public – C:\ProgramData\AspenTech\A1PE\Files\Public
Private – C:\ProgramData\AspenTech\A1PE\Files\Private\<username>
Allow users to save changes they make to plots but not to delete, move, or rename them
As stated in point 2, if the users only has READ permission to a file then they will not be able to save it. If you want users to be able save files (save changes that they make to a plot) but not to be able to delete, move, or rename the file then give the Users Group Read and Write permissions but not Modify. Note: for a1PE files the Read and Read & execute permissions are equivalent.
Visibility of restricted files
If a user does not have the READ or WRITE permission to a file or folder then that item will not be visible to him/her within the navigation menu tree. The files that a user does not have READ permission to will still show up in the Search results though, but if the user clicks on them from Search he will get a File not found error message.

Problem Statement: Occasionally a Customer will get an Error 1935 Message when trying to install HYSYS or AspenPlus products on their laptops, which will prevent the Installation from Completing Successfully.
EXAMPLE: Error 1935. An error occured during the installation of an assembly component. { 303994BA-6487-47AE-AF1D-7AF6088EEBDB}, HRESULT: - 2147024894. | Solution: Error 1935 is often triggered and displayed when there is an issue with installing a .NET Framework Assembly.
And typically there are 3 common reasons for this Fatal Installation Error, which are listed below:
1.) The Pre-Requisite .NET Framework Software and Components have Not been previously installed correctly on the machine.
2.) Or something perhaps either in the Windows Registry or the Windows File System Transaction Log has become Corrupted, and the System thinks it's trying to Install a Non-Assembly file as an Assembly.
3.) The Automatic Windows Updates has been Turned ON and is trying to Install .NET Framework Updates at the
same time you are trying to Install the AspenTech Product Software, which then interferes with the Installation of the
Added or Updated .NET Framework Assemblies that are included with the AspenTech Product Software Installation.
Provided below are Steps that can be taken to Resolve this Error Problem:
1.) Make sure that when Installing AES Applications including HYSYS and/or AspenPlus, that the User Performing the Installation has Administrative Privileges or the machine.
2.) Have the Customer go to Microsoft's Website and check to see if they need any .NET Updates.
3.) Have the Customer Download and Run a Trustworthy Third Party Registry Cleaner or Anti Spyware Software App
like Ad-Aware, SpyBOT, Spyware Doctor, etc., to Clean the Customer's computer of any Spyware Programs that
might be corrupting the registry or interfering with the installation of any Aspen Engineering Suite products.
4.) If Windows Updates is ON, then have the Customer turn OFF Windows Updates and Reboot the computer before trying to reinstall the application.
5.) Review and Complete the Steps documented in KB Article 96547 to Reset the Windows File System Transaction Log in case it has become corrupted.
6.) If none of the above steps work, then can either Request a New Set of DVDs if you still receive Physical Media
(in case the DVDs are scratched or corrupted), or if you obtain the aspenONE Media as a Download from our
Download Center, then try Downloading the Media a second time in case the first download attempt was incomplete.

Problem Statement: How to generate links for Dashboards Layouts in aspenONE Process Explorer? | Solution: Follow these steps to generate a link for a Dashboard Layout that might be useful when linking it to a graphic.
Select the desired template.
Add the graphics to each window by clicking in the folder icon. You would have to navigate through your Public files and select your graphic.
Click on the green check icon:
You would be able to see the graphics is aspenONE Process Explorer:
Click on the Save Button (Floppy Disk) and choose “Save” option. When you use this option, you will be creating a link within the Public folder, so I recommend you to choose the folder of the project which the graphic that will contain the button is going to be saved. For this example, I am saving the dashboard in the folder of the project “Testing1”. Saved Dashboards will appear in this interface with a “Dashboard” icon, similar as in step 1:
Once is saved, click on the “Share Button”, select copy URL, then the link will be available.
That link has to be copied and pasted within the command “window.open(“URL”);” in the Action tab of the button.
If you are going to perform this procedure in the Web Server, when accessing to aspenONE Process Explorer page, change the aspenONE Process Explorer URL in your browser, instead of using “localhost” use the name or the IP address of the web server (just as you usually access to aspenONE Process Explorer from your client machine), then follow steps from 1 to 7.

Problem Statement: After installing Intel Fortran and Visual Studio, I still can not compile or link the Fortran program. How do I set up the compiler to work with Aspen Plus? | Solution: Aspen Plus supports a variety of Intel Fortran compiler versions along with a variety of Visual Studio linker versions. All version of Aspen Plus and Aspen Properties require a Fortran compiler AND linker tools for user and system generated routines. If there are any problems selecting or running a compiler, first install the most recent compilers.cfg or comilers64.cfg file in this link which has the most recent list of supported compiler configurations. Regular updates are made to this document. The compiler.cfg is used for V10 and earlier for 32-bit compiling and compilers64.cfg is used for V11 and later for 64-bit.
Then, run the Select Compiler for V* utility available in the Start menu in the Aspen Plus folder, it will list all of the compiler and linker combinations available. Select your configuration. The State of the configuration must be OK before selecting the option above. If the option for your setup is ERROR then that is not a valid configuration or the software was not installed properly for the Set Compiler program to recognize.

Problem Statement: What is the source of parameter values in ASPEN PLUS built-in pure component databanks? | Solution: Physical property models require parameters to calculate properties. After you have selected the property methods to be used in a calculation, you must determine the parameter requirements and ensure that all required parameters are available. The required parameters can be retrieved from databanks, entered directly on the Methods | Parameters forms, or estimated by the Aspen Physical Property System using the Property Constant Estimation System (PCES). Parameters entered directly on the Methods | Parameters forms are used before databank parameters if they are both available for a given component.
The list of Parameters and Components (with the exception of NIST-TRC) available in each databank is available in the Help under Aspen Plus
Keywords: None
References: -> Physical Property Data Reference Manual. Every parameter is not available for every component in a databank.
PURExx:
The PURExx databanks contain Data from many sources, including DIPPR® ((Design Institute for Physical Property Data), ASPENPCD, API, and Aspen Technology. This is the Primary pure component databank in the Aspen Physical Property System. For a complete list of the parameters available in the databank, see the help. The PURExx databank is generally updated for each version, e.g. PURE37 was delivered in V11, PURE36 was delivered in V10, etc. The oldest versions are periodically archived; however, they can still be added as user databanks if needed. See Knowledge Base document 128743 for instructions about how to add these databanks.
ASPENPCD:
The following parameter values found in the ASPENPCD databank delivered in Aspen Plus 8.5-6 were originally published in Reid, Sherwood and Prausnitz. The PURExx databanks have replaced the ASPENPCD databank.
NIST-TRC:
The NIST-TRC database is provided under an agreement with the National Institute of Standards and Technology's (NIST) Standard Reference Data Program (SRDP). The property parameters and the experimental data used were collected and evaluated by the Thermodynamics Research Center (TRC) using the NIST ThermoData Engine (TDE) and the NIST/TRC Source Data Archival System for experimental thermophysical and thermochemical property data. The NIST/TRC Source data is one of the world’s most comprehensive collections of such data. This databank is much larger than the PURExx databanks. It is updated in each release, but versions from earlier releases are not maintained.
INORGANIC:
The INORGANIC databank contains thermochemical properties for over 2000 mostly inorganic. The INORGANIC databank is used for solids, pyrometallurgical, and electrolytes applications. This data was licensed from I. Barin (Barin, I. (1989). Thermochemical Data of Pure Substances. VCH Verlagsgesellschaft, FRG).
The key data are the enthalpy, entropy, Gibbs free energy, and heat capacity correlation coefficients. For a given component, there can be data for a number of solid phases, a liquid phase, and the ideal gas phase. The same set of parameters are used to calculate enthalpy, entropy, Gibbs free energy and heat capacity for a given phase over a given temperature range.
The parameters in the databank are CPxXPn:
Number of Data Ranges Properties
7 Solid (CPSXP1 to CPSXP7)
2 Liquid (CPLXP1 and CPLXP2)
3 Ideal gas (CPIXP1 and CPIXP3)
In the case of the solid phase, the multiple ranges can also refer to different solid phases of different crystal structure, for the same species.
COMBUST:
The COMBUST databank is a special databank for high-temperature, gas phase calculations. It contains the following parameters for the 59 components typically found in combustion products, including free radicals. The CPIG parameters were determined from data in JANAF tables for temperatures up to 6000K (JANAF Thermochemical Tables, Dow Chemical Company, Midland, Michigan, 1979). Calculations using parameters in the ASPENPCD and PURECOMP are generally not accurate above 1500K.
You may use the COMBUST databank only for ideal gas calculations (IDEAL option set) and only in the following unit operation models: MIXER, FSPLIT, SEP, SEP2, HEATER, HEATX, MHEATX, RSTOIC, RYIELD, REQUIL, RGIBBS, RCSTR, RPLUG, RBATCH, COMPR, MCOMPR, DUPL and MULT. You must enter the option NPHASE=1 for each unit operation block for which it is applicable, and for each STREAM.
The INORGANIC databank contains similar property information, and generally, it applies to a wider temperature range.
AQUEOUS:
The AQUEOUS databank is used for electrolyte applications. The key parameters are the aqueous heat and Gibbs free energy of formation at infinite dilution and the aqueous phase heat capacity at infinite dilution.
These parameters were obtained from Wagman, D.D., W.H. Evans, V.B. Parker, R.H. Schumm, I. Halow, S.M. Bailey, K.L. Churney, and R.L. Nuttall, The NBS Tables of Chemical Thermodynamic properties: Selected values for inorganic and C1 and C2 organic substances in SI units. J. of Physical and Chemical Reference Data, Volume 11, 1982, supplement No. 2.
SOLIDS:
This databank is used for solids and electrolytes applications. This databank is largely superceded by the INORGANIC databank but is still essential for electrolytes applications. Parameters have been collected from various sources, including Wagman et al. used for the AQUEOUS databank.
AP-EOS
The AP-EOS databank contains both unary (CPAAT, CPAAU, CPAAV, CPAM, CPAPC, CPATC) and binary (CPAKIJ and CPAVIJ) Cubic-Plus-Association (CPA) parameters to be used with the CPA property method. The parameter values in the AP-EOS databank are not visible to users. When retrieving parameter values, the Status View for these parameters on the Methods | Parameters | Results forms will be “X” if available though the cell on the Parameters View will be blank. See Knowledge Base document 86017
ACIDGAS:
The ACIDGAS databank contains parameters for pure component, binary, and pair parameters used in Aspen HYSYS and Aspen Properties methods for acid gas treating.
BIODIESEL
The BIODIESEL databank contains parameters for organic compounds typically found in biodiesel production processes, including numerous triglycerides, diglycerides, and monoglycerides.
ETHYLENE
The ETHYLENE databank contains pure component and binary interaction parameters required to model the typical ethylene process. The parameters are for the SRK property method which include the critical temperature, critical pressure, acentric factor and binary interaction parameters. The parameters are available for components commonly encountered in the ethylene process. The data was collected by AspenTech from various sources. Binary interaction parameters were regressed by AspenTech staff.
HYSYS
The HYSYS databank contains pure component and binary parameters used in Aspen HYSYS property methods for compatibility with Aspen Properties in Aspen HYSYS.
NRTL-SAC
The NRTL-SAC databank contains the pure component parameter XYZE for more than 100 common solvents. This parameter contains a representation of each of these solvents as a combination of the four types of segments used in the NRTL-SAC property method. This data is from AspenTech's own development.
PC-SAFT and POLYPCSF
Both the PC-SAFT and POLYPCSF databanks contain parameters used by the PC-SAFT and POLYPCSF property methods. The parameters in POLYPCSF include only those for normal fluids (non-associating) while the parameters in PC-SAFT include parameters for all types of fluids. Values for hydrocarbons and light gases (H2, N2, O2, etc.) are the same in both databanks. POLYPCSF is no longer being updated except to correct any identified errors.
The PC-SAFT databank and PC-SAFT property method are recommended for new applications. For normal fluids and homopolymers, PC-SAFT is a superset of POLYPCSF. For copolymers, the PC-SAFT and POLYPCSF methods generate different results, but the method used by PC-SAFT is recommended by the Consortium for Complex Fluids. We recommend switching from POLYPCSF to PC-SAFT.

Problem Statement: This knowledge base article describes the reasons that can cause Aspen Process Explorer to not function as expected when a Virtual Private Network (VPN) connection is used to connect to the Aspen InfoPlus.21 server.
This article applies to other AspenTech applications such as Excel Add-in or aspenONE Process Explorer. | Solution: Usually when Aspen Process Explorer (APEx) fails to connect to the Aspen InfoPlus.21 server through a VPN connection the cause is an underlying network problem. A basic requirement for Aspen Process Explorer to function properly is that the Aspen Process Explorer client needs to be able to NSLOOKUP to the Aspen InfoPlus.21 server and the Aspen InfoPlus.21 server needs to be able to NSLOOKUP back to the Aspen Process Explorer client machine.
When there are connectivity issues through VPN usually one of these NSLOOKUPs fails. This is frequently because the network/domain controller may not recognize a remote PC logged in through VPN the same way it recognizes the other PCs which are on the network.
AspenTech does not officially test or support Aspen Process Explorer connectivity through a VPN connection.
Some customers have reported that the VPN connection reduces the bandwidth to make data transfer through Aspen Process Explorer too slow to be usable for a normal amount of tags. It is possible to achieve faster Aspen Process Explorer connection speeds if one remotely logs into a PC at work (through Remote Desktop, etc...) then uses Aspen Process Explorer in a normal fashion from the PC at work, instead of from the PC at home.

Solution
Let's review this section by section.
The message below is issued when the non-linear solver diagnostics option Highest residuals is set to a non-zero value (we suggest a value in the range of 2 to 5, to show the top 2 or 5 highest residuals, that means the 2 to 5 equations that are usually preventing the system to be converged).
Newton iteration 0: Highest 2 residuals above tolerance of 1.000000e-005 are
-1.000000e+001 B1.AM_Eqn2
-5.000000e+000 B1.AM_Eqn1

1.000000e+000 B1.y
Note that only residuals actually higher that the equation tolerance (as set in the solver options, absolute equation tolerance, 1e-5) are displayed. This explains why sometimes fewer than the specified number of highest residuals are actually displayed, as in iteration 4 in the example.
It shows the value of the (unscaled ) residual for these equations, which is simply the difference between the left hand side and the right hand side expressions in the equation. When no equation names are specified in the models, ACM gives them a default name, which is AM_EqnNNN where NNN is the equation number (1 for the first equation, 2 for the second, etc - note that in case the model inherits from another model, the equation numbers start from the parent model. In the case of submodels, each submodel has its own equation number counter. In general it is better to give names to equations to avoid having to count equations in a model).
The message also shows the calculated variables involved in the equation that has the highest residual (in absolute value). This shows the current value of the variables, e.g. the values that have been used to evaluate the residuals. The values are displayed in the base units of measurement (typically, Metrics). When variable equivalencing is active (this is the default), all variables in the equivalence are displayed. Note that fixed variables, and variables already solved in previous groups are not displayed.
This information is useful, because you can get an idea of which equation(s) are preventing the system to be converged, and for the highest residual, the current value of the variables involved.
The message below is issued when the value of Highest variable steps is set to a non-zero value.
Newton iteration 1: Highest 2 variable steps above 1.000000e-005 are:
Value Vnorm component Absolute step Variable name
1.00000e+000 6.25000e-001 1.25000e+000 B1.y

The threshold value displayed on the first line (1e-5) is in fact the relative variable tolerance, as specified on the Solver options, Tolerances sheet.
Value shows the current value of the variable at which the residuals (and Jacobian matrix) have been evaluated. This is the value before the solver step is applied. The value is displayed in the base units of measurement of the variable.
Vnorm component shows the value of variable norm for this variable. Note that the variable norm is the maximum of the variable norms components over all variables - i.e. the first variable shown in the highest variable steps.
Absolute step - this shows the step to be taken by the variable. This step size is the one calculated by the solver, before any step cutting is applied due to bounds or step range option.
The definition of Vnorm is the absolute value of the step size, divided by the absolute value of the variable plus the ratio of the absolute tolerance over the relative tolerance:
Vnorm = abs(step) / (abs(x) + abstol/reltol)
This information is useful because it shows the variables that are changed by the largest amount. Large variable changes may indicate a very sensitive problem, which can be caused by the non-linear nature of the problem, or by poor variable scaling, or poor starting values for the non-linear iterations.
When you see that the variable steps are very small but the residuals are still larger than the equation tolerance, you should also suspect a scaling issue. As the variables are not changed by a significant amount, it is unlikely to make any further progress. Sometimes this can be caused by numerical noise in procedures, or incorrect equation scaling. It is also possible that the system actually has noSolution. A practicalSolution is to change the solver convergence criteria to Variables or Residuals (on the non-linear solver sheet).
The variables step convergence criteria is satisfied when the largest vnorm is smaller than the relative tolerance. This test corresponds to:
abs(step) < (abs(x) * reltol + abstol)

Problem Statement: Regression of equilibrium constants with pH data set will not work in true component approach | Solution: Equilibrium constants of an equilibrium chemistry reaction can be regressed with the following data-sets:
TPX or TX ( for Salt Precipitation reactions)
TXY, PXY or TPXY
pH
When pH data set is used for regressing equilibrium constants for an equilibirum chemistry reaction, regression run case will fail while using the true component approach.
*** CANNOT SATISFY CONSTRAINTS ***
** ERROR WHILE EXECUTING DRS CASE: xxx
CONSTRAINTS CANNOT BE SATISFIED FOR THIS CASE.
True component approach represents system composition in terms of concentrations of the true species that exist in a chemical equilibrium, whereas Apparent component approach represents in terms of concentration of the apparent components that exists prior to the reactions which occur inSolution.
pH represents the acidity or alkalinity of aSolution on logarithmic scale.
Both these approaches are computationally equivalent and hence regression run case using pH data set will only be satisfied when Apparent component approach is used.

Problem Statement: How do I create a pipe demolition item and remove the x-ray work items from it? | Solution: In order to generate the costs for a demolition item (DEML), the Economic Evaluation cost engine actually calculates the cost to design and install the item, then it backs out all those material costs, zeroes them out, and then the cost engine reports only the manhours and labor cost to demolish the item.
For pipe demolition, the x-ray work items are not deleted. This is as per the Economic Evaluation design and the reason behind it is to give users a method to quickly estimate the demolition based on what it took to install in the first place. This is in no way intended to be a complete demolition methodology.
Follow the steps below to create a pipe demolition item and remove the x-ray work items:
1. Add a component for Above Grade or Buried Piping which is under Project Components | Plant Bulk | Piping.
2. Specify the required inputs such as Pipe length, Pipe Diameter, Flowrate, etc.
3. To create a demolition item, find “Installation option” under the input sheet, click the arrow for the dropdown menu, and choose option DEML (Demolition of component and installation bulks) as shown below:
Note: If you are working in an older version where the Installation Option is not available in the main input sheet, you can still find it by going to Options | Mat'l/Man-Hour % Adj Vessel Tracing, under the SPECIAL OPTIONS section.
4. Now evaluate the project and generate the installation details excel report and you will find that piping x-ray work item is not deleted as shown below:
5. To remove the x-ray work from the demolition item, simply scroll toward the bottom of the piping input sheet and make the Weld Xray percent zero as shown below:
6. Re-evaluate the project and generate the installation details excel report, and you will find that x-ray item is deleted as shown below:

Problem Statement: There is a real-time MW tag in InfoPlus.21 database; we want to convert it to an hourly MWH tag and add the hourly MWH output to itself continuously. How to convert a real-time MW tag to an hourly cumulative MWH tag using Aspen Calc? | Solution: 1. Create a new IP_AnalogDef record called MWH in InfoPlus.21 database.
2. Create new function MWH=MWH+(TagAverage(MW, Now()-1:00 , Now(), 0, 0)) in Aspen Calc (MWH = MW * T. In order to calculate the hourly MWH, the MW here will be the average MW in one hour, and the T here will be 1 hour).
3. Bind the MW to the real-time MW tag; bind the MWH to the newly created MWH tag.
4. Set the MWH tag in IP.21 to 0 when initially starting the calculation, and add this calculation to OneHour schedule.
As a result, the MWH tag after the first hour will be zero plus the average of the first hour MW; the MWH tag after the second hour will be the MWH after the first hour plus the average of the second hour MW; the MWH tag after the third hour will be the MWH after the second hour plus the average of the third hour MW, etc... The MWH tag has been calculated and cumulative hourly.

Problem Statement: Why do I observe Error E072, Group XXX must also have MEMBER Stream GRO in Table PINV, even though there is no GRO stream in my model? | Solution: The problem is that column GROUP in table GROUPS in the CASE table is being truncated and processed as stream GRO. PIMS DR thinks that row XXX in table GROUPS includes member stream GRO and since group XXX is in PINV, all its components including GRO must also be in PINV.
This happens because group XXX is not in BUY or SELL, so it's not being treated as a normal group that requires a number.
PIMS AO will not present this behavior because it ignores the column GROUP in the CASE table.
A simple workaround is to remove column GROUP from the table GROUPS in the CASE table.

Problem Statement: A controller with a large list size may not write out to the DCS despite all indications that the writes are successful. This is observed on a Honeywell TPN OPC server running on an eApp. | Solution: The LISTSZ parameter (Condifure section) of a controller determines the list size for the PUT and WRITE requests to the CIMIO server. Each OPC server may react differently to the various size of the lists. On the Honeywell new eApp running with R410 software, a list size larger than 420 will cause the writes to fail without any error. All CIM-IO logs show normal, successful writes to the OPC server even though the values never make it out the DCS points.
To fix this error, reduce the LISTSZ until the DCS value matches what the controller is writing out.
The information we got from some of our clients indicates that-
R410 eApp – problems with failing to write the whole list. Reducing LISTSZ to fix it. The value of the LISTSZ that works seem to vary after each eApp reboot.

Problem Statement: How do I migrate Aspen Mtell assets, along with their agents, from one database to another? | Solution: When Aspen Mtell assets and their agents are being migrated, it is important to ensure that all additional dependent items - like the equipment hierarchy, work orders, equipment sets and sensor groups - are also migrated. This master knowledge base article breaks the process into two main sections - the export from the originating database and the import into the destination database - and provides steps for each section. Please click on each step to access a knowledge base article explaining it.
A. Export
1) Exporting equipment hierarchy as .csv files
This step can be skipped or done partially if a complete or partial hierarchy already exists in the destination database (when merging with an existing database), otherwise it is recommended to start at the beginning.
2) Exporting work orders as .csv files
This should be done for the asset that is being migrated. It can be skipped if the asset and its work orders already exist in the destination database's hierarchy.
3) Exporting equipment sets as .csv files
This is a critical step in the migration process. Make sure the Sensor Data Source name in the Tagsource column of the exported .csv file exists in the destination database. If the name of the Sensor Data Source is different in the destination database, this change must be reflected manually by changing the contents of the Tagsource column in the equipment set exported .csv file.
4) Exporting machine learning agents as .mtell files
B. Import
1) Importing equipment hierarchy from .csv files
This step can be skipped or done partially if a complete or partial hierarchy already exists in the destination database (when merging with an existing database), otherwise it is recommended to start at the beginning.
2) Importing work orders from a .csv file
This step can be skipped if the migrating asset and its work orders already exist in the destination database's hierarchy..
3) Importing equipment sets from .csv files
This is a critical step in the migration process. Make sure the Sensor Data Source name in the Tagsource column of the .csv file being imported exists in the destination database. If the name of the Sensor Data Source is different in the destination database, this change must be reflected manually by changing the contents of the Tagsource column in the .csv file that will be imported.
4) Importing data from the historian to populate TDS
Importing the equipment set will create a default hourly TDS without data. Edit the new TDS to match the TDS in the originating database in terms of Date Range, Granularity, Name, etc., then import data to the new TDS before moving forward.
5) Importing sensor groups from .csv files
Refer to the Create Sensor Group using excel file section of the knowledge base article to create sensor groups identical to those in the originating database and import them into the destination database.
6) Importing machine learning agents from .mtell files
This completes the procedure for migrating Aspen Mtell assets, along with their agents, from one database to another.

Problem Statement: How can both the datasource and repeat area field of a tag be specified in an ad-hoc calculation? | Solution: The on-line help files provide the following two recommendations for specifying the data source and the field of a tag.
1. Specify a datasource using the following template: datasource:tagname
e.g. =TIGER:ATCAI+BANGOR:ATCAI
where the data sources in this example are TIGER and BANGOR.
2. Specify a particular tag's field using this template: {tagname <repeat_area_number> field_name}
e.g. ={ATCAI IP_INPUT_VALUE} (for a fixed-area field)
or ={PVRECORD 1 IP_TREND_VALUE} (for a field in repeat area #1)
These two features can be combined to configure an ad-hoc equation to use a specific field of a tag in a unique datasource. For example:
=datasourceA:{record_name 1 field_name} + datasourceB:{record_name 1 field_name}
where 1 is the number of the repeat area that is to be accessed.

While the Tee does correctly split the overall component flows, the Electrolyte flows (Stream Worksheet tab | Electrolytes form | Composition radio button | Molar or Mass radio button | Molar or Mole Flow column) are not split appropriately. The electrolyte molar and mass flows in the two outlet streams are identical as the amount in the inlet, which is wrong. | Solution: This is a known issue still being investigated. In the meantime, there is a workaround as described below.
In order to resolve this issue, send the incorrect stream through a mixer or a valve and then view the outlet Electrolyte flows. The downstream Electrolyte molar and mass flows will now be fixed. The reason it changes across the valve or the mixer is because the outlet is stream is flashed (recalculated), while the outlet from the Tee is not.

How can I use MS Excel to retrieve the heating and cooling curve of a heat exchanger in user specified units? - https://esupport.aspentech.com/S_Article?id=000089201
The attached Excel file has VBA codes that allow extracting heating curves and other properties to a spreadsheet. You will be able to select the heat exchanger from MS Excel file and choose the tube side or shell side.
If customization is needed, you also can add new properties by adding in the code with different moniker names. You can find those properties' moniker names in the installation folder (for example: C:\Program Files\AspenTech\Aspen HYSYS V11.0\Support\heatexch.rdf).
Note that, in order to get the heating curve, you should use Weighted design method in HYSYS exchanger. The number of points can be adjusted by the number of interval of each side.
Follow the below steps to run the VBA code:
1. Open your HYSYS model. Take care to keep only one simulation open. The code will only work if HYSYS is open. You can use any version of HYSYS. You can use the provided HEAT EXCHANGER.hsc to run a test.
2. Open the attached Excel file Get HX Curves and Properties.xls.
3. Click Open Hysys Case. A message Case found should pop up to let you know that it's able to connect to your HYSYS model. You will then be able to pick a heat exchanger from the drop down list under Pick Heat Exchanger Name.
4. Click Get Available Curves to obtain the list of curves if the drop down menu.
5. After this, select the curve you want to extract from the drop down menu Pick a curve. Then hit Get Curve Data. Information should be populated in the Curve Data table

Problem Statement: How do you model a gas-phase (UNIPOL) process to product linear-low density polyethene (LLDPE) or high-density polyethylene (HDPE)? | Solution: Attached is a model of a gas-phase (UNIPOL) process to product linear-low density polyethene (LLDPE) or high-density polyethylene (HDPE) in Aspen Plus. This model will run in Aspen Plus V10 and higher.
This configuration is known as a ‘swing’ reactor. It can make either product – butene or other alpha-olefins are added to shift the recipe from HDPE to LLDPE.
This model assumes a single-site metallocene catalyst. The rate constants are representative of typical industrial catalysts but does not reflect any particular catalyst – the model should be calibrate against plant data as needed. The physical properties are based on PC-SAFT and are based on calibrated unary and binary parameters.
The model treats the gas-phase reactor as a CSTR since the CSTR accurately reflects the well-mixed behavior of the UNIPOL reactor. The specified “liquid” phase holdup actually refers to the volume of solid particles in the reactor. Aspen Polymers treats solid polymers as a pseudo-liquid in order to take advantage of phase equilibrium calculations (e.g., to estimate solubility of the monomers in the polymer phase).

Problem Statement: I have mixture viscosity data for different concentrations of polymer in a solvent, for different molecular weights of the same polymer. How can I regress the Aspen Polymer Mixture Viscosity Model binary parameters from this data? | Solution: The Aspen Polymer Mixture Viscosity model uses the pure component viscosities, which for the polymer components are calculated from the Modified Mark-Houwink/van Krevelen model. This model takes into account the dependence of the polymer's viscosity on the molecular weight:
On the other hand, the Aspen Polymer Mixture Viscosity model binary parameters (MUKIJ and MULIJ) are almost independent of the polymer molecular weight. Therefore, you can regress the parameters for one data set with a fixed molecular weight (an oligomer type component with a specified number of segments), and use the same parameters for different oligomers or for the polymer component.
The attached Aspen Plus backup file can be opened in V9 and higher. The viscosity data in the example is not actual experimental data. This regression is for illustration purposes only.

Problem Statement: Is the ACM language similar to gProms. Is this true? Is there a quick way to translate from gProms to ACM for the isotherms implementation? | Solution: ACM is similar to gProms in a way they are all equation based solver, it is pretty similar, but ACM can use the Aspen Property database.
Aspen Adsorption is library we developed tailored on gas adsorption based on the framework of ACM. The language is ACM, but it already has the Adsorption library such that user just need to configurate the bed, isotherm, balance equation, etc.
If the user want to use Aspen Adsorption for their gas adsorption process, the transfer from gProms to Adsorption should be build the model in the Aspen adsorption. If the user has their own isotherm, Aspen Adsorption’s User Submodel can handle that.

Problem Statement: Since Actual Volume Flow uses rigorous density calculations at the stream conditions, it can not be directly specified for a material stream. (For descriptions of different types of volume flows, refer to the following KB: https://esupport.aspentech.com/S_Article?id=000089966) | Solution: To specify an Actual Liquid Volume Flow, you must use an Adjust block. This operation will adjust an input flow rate until Actual Volume Flow reaches the correct value.
1) Fully specify a material stream with compositions, stream state, and a flow rate (Liq Vol Flow @ Std used in this case)
2) Add an adjust block with the specified flow rate as the Adjusted Variable, Actual Volume Flow as the Target, and the desired actual flow
3) Change the tolerance and max iterations of the adjust block and select Start
4) The adjust block will solve for the specified Actual Volume Flow

Problem Statement: How can design gauge pressure impact the design and cost of column nozzles? | Solution: Design gauge pressure impacts the nozzle class predicted and, by extension, the equipment total and direct cost. A multiple diameter tower will be used to illustrate this impact. If there are two towers with identical heights and diameters, but one is at 15 psig while the other is at 3000 psig design pressure, then the cost of the 3000 psig tower will be greater.
The Design Data Sheet in the Reporter Report of each component displays the design basis for each tower. To enable the Reporter Report, go to Tools | Options | Preferences | General tab | Item Report. Open each component individually and click the Evaluate button to view the Item Report. The Design Data Sheet is the middle tab at the top of the item report.
The Nozzle ASA rating CLASS for the 3000 psig tower may be almost 10 times that of the 15 psig tower. The Nozzle ASA rating value is generated by the system based on the design gauge pressure and can be found in the Nozzle And Manhole Data section of the Reporter Report.
A higher nozzle rating indicates larger manholes and thicker nozzles for the high pressure tower than that of the 15 psig tower. The cost of nozzles and manholes will also be greater, therefore resulting in higher equipment and installation cost for the 3000 psig tower. Note the vessel wall thickness will also be greater, further increasing the extra cost of the high pressure tower.
It is important to look at the design data sheets when comparing equipment items to see what the drives the equipment design, and by extension the cost, as a result of what is defined in the component input specs form.

Problem Statement: How to get component qualities blend by blend in MBO? | Solution: In Table _TANKS_MBO, users can get component qualities values by blend, which is the same as those in AB_TANK_QUALITIES. AB_TANK_QUALITIES is created after exporting blends while _TANKS_MBO is created when publishing results.
Users can also use GetAllValsForTankRStrmProp, GetTankProp or GetStrmProp automations to get tanks or streams properties so as to get the properties for components.
GetAllValsForTankRStrmProp: Use this method to get (retrieve) a specific tank or stream property value for each period.
GetTankProp: Use this method to get (retrieve) the property value for a specific tank from the simulator.
GetStrmProp: Use this method to get (retrieve) the property value for a specific stream from the simulator.

Problem Statement: When working in the submodels window of Aspen Petroleum Scheduler, after clicking on “Update Submodel | Solution: When working with submodels in APS, material balance rows (VBAL or WBAL) are mapped as product yields. If you have specified the APS stream in the Stream section of the Build ref tab, then it will be mapped to a material balance row, so it will display as an output.
To solve it you can go to the Summary tab and delete the unwanted output reference by clicking the X next to the stream.

Problem Statement: Are any recommendations how to switch from gProms to the Aspen Adsorption? | Solution: It is always good to decompose the model into pieces and steps for validation.
For example, firstly, user should start from validation of isotherm, then build the flowsheet for the process, but validate the first step. Finally, validate the whole flowsheet with whole cycle.

Problem Statement: Can a column calculate backwards? | Solution: The column solver works independently from the HYSYS main solver; as a consequence, calculations take place only in the forward direction when solving a column subflowsheet. In other words, all feed streams must be fully specified in order for the column to solve. If you know the outlet streams and wish to find the feed composition, you can simply mix the column outlets together using a mixer block.
