Abstract
A rapid pressure swing adsorption process utilizes two or more adsorbent beds, each of which undergoes on a cyclic basis, high pressure feed-adsorption, countercurrent exhaust and repressurization. The feeding of the feed gas mixture, such as air, to the adsorption system is temporarily discontinued upon completion of the feed step to each bed, with the discontinuity of feed before commencing the passing of said feed gas mixture to the next succeeding bed being essentially the same throughout the processing cycle, with the feed step at adsorption pressure for each bed being essentially the same and with said feed step being shorter in duration than said exhaust step.
