I am not familiar with Aspen Adsorption, but I need to simulate CO2/H2 separation using Pressure Swing Adsorption (PSA) by activated carbon (AC) or zeolite. The feed gas is rich H2 gas (55%-mol) from WGSR with CO2 impurities (45%) at 30 bar. I want to know the purity and recovery of H2 after PSA separation. Is it possible to simulate this case in Aspen Adsorption (ADSIM)? Please help! Thank you
