How to optimize number of theoretical stages in reactive, rectifying and stripping section using sensitivity analysis tool in ASPEN Plus? what would be the independent variable and dependent variable? Kindly explain i am performing simulations on reactive distillation process.
I don't think it is possible to optimize the number of stages as it is automatically generated based on the column design and operating conditions. Trial and error is recommended in your case. Have scenarios of + and - 10% of each operating variable (temp, pressure, RR,... etc) then check out the process performance to compare between these scenarios. For the reactive stages, I think you can initially assume, for example, 5, 10, 15 and 25 reactive stages, then compare the reactive distillation performance. I wish you the best.
Thanks for your kind answer and I want to ask how can I check the performance of reactive stages like how many stages should be in a reactive section ? you mean I have to run number of simulations and in each simulation I will increase or decrease reactive stages in a sequence (keeping other stages in rectifying and stripping fix) and then check its effect on the key component purity. Am I right? Tasneem Muhammed
Precisely! @Abdul Wahab
