<p>A single-bed PSA system comprising a blower (5), an adsorber vessel (13), and a gas product storage tank (21) separates a gas mixture (1) using a three-step cycle comprising adsorption, evacuation, and pressurization. Pressurization is accomplished by introducing product gas, preferably directly from the gas product storage tank (21), into both the feed end and the product end of the adsorber vessel (13). Preferably a portion of the pressurization gas is introduced into the adsorber vessel (13) by the blower (5), which also is used for providing feed to the adsorber vessel (13)and for withdrawing gas from the adsorber vessel (13) during the evacuation step.</p> |
