Simulation of fluctuations in raw material composition

In a certain gas separation unit, liquefied gas containing propylene is processed – some of this liquefied gas is purchased from external sources in order to improve efficiency. Due to process limitations, the externally sourced liquefied gas can only be processed intermittently, and its propylene content differs significantly from that of the liquefied gas produced by the factory itself. Once mixed, these two types of liquefied gas enter the feed tanks for gas separation. In such a situation, if one wants to monitor how the operating parameters of the various towers change over time, is it necessary to use a dynamic model?
This can be done using a dynamic model; there should be no problems.
This depends on the propylene content in the purchased liquefied gas; if the propylene content exceeds the design value of the tower, no action taken will result in satisfactory outcomes, unless the operating conditions of the tower are changed
