How to use Aspen to determine the temperature sensitivity plates for a distillation column based on sensitivity criteria
Thread Content
The sensitivity criterion involves altering a controlled variable (such as the reflux flow rate or the reboiler load) by a small amount (0.1% of the design value) in order to examine the changes in tray temperature, thereby identifying the tray with high temperature sensitivity. What I want to know is how to change this controlled variable (the reboiler load) in Aspen, because when designing the tower parameters I did not set the reboiler load as an operating variable; instead, I set the reflux ratio and the top flow rate. How can I implement this sensitivity criterion? I seek guidance from experts; thank you! ! ! ! ! ! ! ! ! ! !
The requirements in the design specs and the operational variables in the setup are unified; there are no requirements specified in sensitivity
