    摘要： Pressure swing adsorption system comprising two or more vessels, each having a feed end, a product end, and adsorbent material adapted to adsorb one or more components from a multi-component feed gas mixture; piping adapted to (1) introduce the feed gas mixture into the feed ends, withdraw a product gas from the product ends, and withdraw a waste gas from the feed ends of the vessels, and (2) place the product ends of any pair of vessels in flow communication; a feed pipe adapted to supply the feed gas mixture to the system; a product pipe adapted to withdraw the product gas from the system; and a waste gas pipe adapted to withdraw the waste gas from the system. An indexed rotatable multi-port valve is adapted to place the product end of each vessel in sequential flow communication with the product end of each of the other vessels.

    摘要： PSA process for oxygen production comprising (a) providing an adsorber having a first layer of adsorbent selective for water and a second layer of adsorbent selective for nitrogen, wherein the heat of adsorption of water on the adsorbent in the first layer is ≦ about 14 kcal/mole at water loadings≧ about 0.05 mmol per gram; (b) passing a feed gas comprising at least oxygen, nitrogen, and water successively through the first and second layers, adsorbing water in the first layer of adsorbent, and adsorbing nitrogen in the second layer of adsorbent, wherein the mass transfer coefficient of water in the first layer is in the range of about 125 to about 400 sec−1 and the superficial contact time of the feed gas in the first layer is between about 0.08 and about 0.50 sec; and (c) withdrawing a product enriched in oxygen from the adsorber.
