Removal Of Gaseous Contaminants From Argon |
摘要 |
Method for argon recovery that comprises (a) providing a feed gas mixture comprising argon and nitrogen; (b) contacting at least a portion of the feed gas mixture with a nitrogen-selective adsorbent in a cyclic pressure swing adsorption process and adsorbing at least a portion of the nitrogen on the adsorbent in a first pressure range above 100 psia to provide a purified argon product and an adsorbent comprising adsorbed nitrogen; and (c) desorbing the adsorbed nitrogen in one or more regeneration steps effected in a second pressure range between atmospheric pressure and a super-atmospheric pressure below any pressure in the first pressure range, inclusive; wherein the cyclic pressure swing adsorption process is effected at an average operating temperature of at least about 0° C.
