I hope you are well. I am designing a double column cryogenic distillation unit to produce high purity nitrogen gas. My air composition includes nitrogen, oxygen, argon, carbon dioxide, water vapour and traces of THC’s. I am struggling with starting my simulation on Aspen plus as there is no option to model an adsorption column to remove the CO2, H2O and THC’s. How should I go about this? What units should I include in order to optimise my design making it cost effective and energy efficient. I also was wondering how I would go about sizing both distillation columns, please do let me know and if there are any resources which would help.

Check for PSA (pressure swing adsorption).

I am hoping to go with cryogenic distillation over PSA, how can I simulate an adsorber on Aspen plus
