خلاصه مقاله:
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 bulkseparation 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.
