    摘要: A process for obtaining high concentration argon from air by means of pressure-swing-adsorption, characterized by passing air through a zeolite molecular sieve-packed adsorption apparatus and a carbon molecular sieve-packed adsorption apparatus in this order, subjecting the air to pressure-swing-adsorption operation independently in the above pieces of adsorption apparatus, thereby obtaining concentrated argon and high purity oxygen simultaneously.

    摘要: In a process of recovering oxygen-enriched gas by pressure swing adsorption with use of adsorbers (A, B) each packed with an adsorbent which selectively adsorbs nitrogen from a gas mixture mainly containing nitrogen and oxygen, recovery of remaining oxygen-enrich gas is fully carried out by pressure equalization between both adsorbers (A, B), and a vacuum pump (8) is always connected to either adsorber (A or B) for continuous evacuation of nitrogen. For this purpose, the pressure equalization between both adsorbers (A, B) is conducted at least in two steps wherein one adsorber (A or B) is pressurized, whereas the other adsorber (B or A) is pressurized, so that recovery of oxygen-enriched gas is possible until there is substantially no pressure difference between both adsorbers (A, B).

    摘要: A hydrogen gas separation method utilizing PSA process employs a plurality of adsorption towers A, B, C loaded with an adsorbent for separating the hydrogen gas from a hydrogen-containing gas mixture, and a cycle including introducing the gas mixture into the adsorption tower, adsorbing unnecessary gas in the gas mixture by the adsorbent, leading out product gas having high hydrogen concentration from the adsorption tower, desorbing the unnecessary gas from the adsorbent, and leading out desorbed gas containing the unnecessary gas and residual gas in the adsorption tower from the adsorption tower, is repeated. The adsorbent includes an activated carbon-based first adsorbent D located on the upstream side of the flow direction of the gas mixture in the adsorption tower with an filling ratio of 60 to 80%, and a zeolite-based second adsorbent E located on the downstream side of the flow direction with filling ratio of 40 to 20%.
