摘要
Process step in a pressure swing adsorption process using multiple parallel adsorbent beds operating in cyclic process steps to recover a less strongly adsorbable component from a feed gas mixture containing at least one less strongly adsorbable component and at least one more strongly adsorbable component, wherein each adsorbent bed has a feed end and a product end, wherein each bed is subjected to at least a feed/product step, one or more depressurization steps, a purge step in which a purge gas enriched in the less strongly adsorbable component is introduced into the product end of the bed and a purge effluent gas is withdrawn from the feed end of the bed, and one or more repressurization steps. The process step comprises introducing at least a portion of the purge effluent gas from a first bed into the feed end of a second adsorbent bed at any time other than during the feed/product step in the second adsorbent bed.
