 of the sample from the interior of a process plant through the walls of the pipes or other pressure vessels which contain the process requires tapping the process to obtain the sample, and this must be done without permitting the sample to escape to atmosphere. Except in rare cases, such a sample is at least partially, and often extremely volatile. In any event, a sample must be removed from the processing plant, transferred through a set of flow lines, metered into some sort of sample container, and then delivered for subsequent testing, for instance, at a testing laboratory sample analysis or other testing can be carried out. One mode of testing is to fill a small sample container, carry it to the testing lab, and conduct the test there. This enables a single testing lab to test samples from several different locations on a process plant. For instance, a single process plant may comprise several different columns with intermediate stages of processing, thereby generating samples at 10 or 20 different locations; samples are obtained at different times of the day from the several sample locations, the tests are then run, and product quality and purity is then certified as a result of the laboratory testing.
The present apparatus and method enable periodic testing to be carried out in this fashion. This disclosure sets forth a means and mechanism for such testing notwithstanding the fact that testing is required of the product when the product is manufactured at extremely high pressures and temperatures. Immediately, there is a problem in removal of the sample. For instance, as a result of high process temperatures, the removed product typically will be a gas, and will tend to be reduced in size should it undergo a phase conversion from gas to liquid. On the other hand, because of extremely high pressures, a sample will tend to expand when the pressure confinement is reduced. It is therefore somewhat difficult to scale the amount of sample to be removed so that the proper size and consistent size of sample can be provided in a sample container. The present apparatus enables this to be accomplished. Moreover, it is accomplished in the context where one or several sample containers can be serially filled with each separated from the other at the sample taking stage. The timed separation of samples is accomplished by providing fixed flow lines extending to the sample receiving container which are periodically purged with nitrogen to assure that there is no remnant of sample gas in the lines for later sample collection. The purging of lines assures that two samples taken hours apart are not mixed serially by storage in the connective lines.

In any event, a sample must be removed from the processing plant, transferred through a stage set of flow lines, metered into some kind of sample container, and then delivered for subsequent examination, for instance, at a examination laboratory sample analysis or other testing can be carried out. One mood of testing is to fill a small sample container, carry it to the testing lab, and conduct the test there.

 The present apparatus and method enable periodic testing to be carried out in this manner. This disclosure sets forth a means and mechanism for such testing notwithstanding the fact that testing is required of the product when the product is manufactured at extremely gamey pressures and temperature. Immediately, there is a problem in removal of the sample distribution. For instance, as a result of high process temperature, the removed intersection typically will be a gas, and will tend to be reduced in size should it undergo a phase conversion from gas to liquid. On the other hand, because of highly high pressures, a sample will tend to inflate when the pressure confinement is reduced. It is therefore somewhat unmanageable to scale the amount of sample to be remove so that the proper size and consistent size of sample can be provided in a sample container. The present apparatus enables this to be accomplished. Moreover, it is achieve in the context where one or several sample containers can be serially filled with each separated from the other at the sample distribution taking stage. The time separation of samples is accomplished by providing fixed flow cable extending to the sample receiving container which are sporadically purged with nitrogen to reassure that there is no remnant of sample natural gas in the lines for later sample solicitation. The purging of lines assures that two samples taken hours apart are not mixed serially by storage in the connective lines. furthermore, this is all achieve without permitting fugitive emissions to atmosphere.
