Your value-added partnership with Arkema, the worldwide molecular sieves supplier
Since 1958 Arkema has been a major player in molecular sieves and a renowned expert in the field with its Siliporite® registered trademark.
Hydrogen purification by Pressure Swing Adsorption (PSA)
The PSA process removes 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 then desorbed at low pressure as an off-gas stream. This is achieved with molecular sieves such as Arkema’s Siliporite® PHYG products.
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.
