Summary

Simple equilibrium theory-based formulations were derived and used to investigate the feasibility of complete cleanup in the performances of pressure swing adsorption (PSA) and vacuum swing adsorption (VSA) air purification processes. Three representative contaminants were investigated (dimethyl methylphosphonate, benzene and butane), all on activated carbon. VSA appeared superior to PSA from the point of view of complete cleanup during every cycle, pressure ratio required for complete cleanup and processes with incomplete cleanup. The superiority of VSA over PSA also became more pronounced with higher pressure ratios and lower purge-to-feed ratios.
