Oxygen enrichment from air by pressure-swing adsorption (PSA) ... Compressed air enters the adsorption bed at high pressure. Typical adsorbents are usually based on zeolites. Because zeolite has a higher selectivity for nitrogen、and oxygen is at a lower partial pressure、nitrogen is adsorbed to an appreciably greater extent and oxygen-enriched air is obtained at the outlet. The bed is then blown down to a lower pressure to desorb nitrogen. A purge step may sometimes be used to sweep nitrogen out of the bed before a new cycle begins.、Membrane separation of oxygen is accomplished by a thin polymeric film that allows selective transport of oxygen through it as a result of a driving force、such as differential partial pressure. ... Oxygen dissolves into the membrane at its upstream surface and diffuses across the membrane to the downstream surface、where it volatilizes into the adjacent gas phase. Other gases in air also dissolve into the membrane and diffuse along with oxygen、the most important of these is nitrogen. ... Selectivity of a membrane material for oxygen becomes an important design parameter. The preferred membrane material must have both a high permeability and a high selectivity for oxygen.、Oxygen from cryogenic air separation. .. Cryogenic air separation involves three steps: 1) purification of the incoming air to remove particles、carbon dioxide、and water、2) refrigeration and economization of refrigeration values contained in the product and waste streams、and、3) separation by distillation.、Obtained on large scale by liquefaction of air、For more Methods of Manufacturing (Complete) data for OXYGEN (8 total)、Impurities:、Possible impurities:、Argon、krypton、xenon、methane、ethane、ethylene、carbon monoxide、nitrous oxide、halogenated refrigerants、solvents、some impurities may be generated from the production process、Formulations、Preparations: Liq: Purity: 99.5+%.、Grades: low purity、high purity、USP.、Type I、gas、Grades、O2 min: A、99.0%、B、99.5%、C、D、E、99.6%、F、99.995%.
