Simulation of pressure swing adsorption (PSA) process has been performed for production of high purity H2
form steam reforming off-gas. PSA is an efficient process to produce pure H2 from the steam methane reformer
off-gas. In this work, simulation of a multi-step PSA process was performed by ADSIM ASPEN for bulk
separation of H2 from H2/CO/CO2/CH4/N2 (75.7/0.7/18/3.2/2.4 vol %) mixture. A two layered activated
carbon/zeolite bed was used as the adsorbents. The influence of feed flow rate, purge to feed ratio and lengths
and diameter of adsorbent layers on the system performance is investigated. When the pressure is cycled between
1 and 22.5 bar, 75.7% H2 in the feed could be concentrated to more than 99.95% in the product with 82.5%
recovery.
