PSA process applying adsorption technology has been extensively studied and developed as an energy-saving separation process in recent years. Applications of PSA process have been extended with growing attention to environmental problems. Two cases (case 1 : blowdown+purge, case 2 : blowdown) of PSA process were studied for hydrogen of production from gas mixtures of CO-H₂ and CO₂-H₂. Restrictions on PSA process and the effects of pressure, feed concentration and gas velocity on recovery have been obtained from material balance on adsorption column using uncoupled linear isotherms and local equilibrium model. Process parameters such as feed gas velocities, purge-to-feed ratio, and the simulation results were analyzed to investigate recovery and purity of products.
