초록

A single-bed PSA system comprising a blower, an adsorber vessel, and a gas product storage tank separates a gas mixture using a three-step cycle comprising adsorption, evacuation, and pressurization. Pressurization is accomplished by introducing gas from the gas product storage tank into both the feed end and the product end of the adsorber vessel. Preferably a portion of the pressurization gas is introduced into the adsorber vessel by the blower, which also is used for providing feed to the adsorber and for withdrawing gas from the adsorber during the e...

[ I claim:] [1.] A pressure swing adsorption process for the separation of a pressurized feed gas mixture containing at least one more strongly adsorbable component and at least one less strongly adsorbable component comprising the steps of:(a) introducing the pressurized feed gas mixture into a feed end of a single adsorber vessel containing a solid adsorbent which preferentially adsorbs the more strongly adsorbable component, withdrawing from a product end of the adsorber vessel an adsorber effluent enriched in the less strongly adsorbable component, p...
