Hydrogen purification by Pressure Swing Adsorption (PSA)

The PSA process involves the removal of impurities from a hydrogen rich feed gas by running the gas at high pressure through a fixed bed packed with different adsorbents. The impurities are subsequently desorbed at low pressure as an off-gas stream. Products can become 99.999% pure.

Various hydrogen rich feedstocks can be treated, including steam reformer gases, methanol and ammonia off-gases, refinery gases, ethylene cracker gases, coke oven gases, etc.

Main consumers of purified hydrogen are refineries (cracking, desulphurization and dearomatization processes) and the petrochemical industry (methanol and ammonia synthesis, MTBE processes, etc.) High performance and dependable Siliporite® molecular sieves are the best product for this application.
