How can I simulate a PSA system in DWSIM?

[Lisandro211]

I want to dry a Hydrogen stream that has vapour on it, and the method i find more suitable is the PSA system, but i don't find it in the dwsim software, can somebody explain me how to do it?

Thank You

I am not sure you can use PSA in DWSIM. PSA, or Pressure Swing Absorption is a cyclic process in time. DWSIM is first a steady state simulator with the ability to look at time periods. To stop and blowdown a PSA unit and restart it may be beyond DWSIM's capabilities.
Anyway, there is no unit operation called PSA in DWSIM. At best you might be able to simulate part of the PSA cycle using some sort of reactor.
