ABSTRACT:
High purity strongly adsorbed gas, e. g., carbon monoxide, is separated from a gas mixture containing one or more other gas components, e. g., hydrogen carbon dioxide, methane, nitrogen and possibly other impurities, by a two-phase pressure swing adsorption process carried out in one or more adsorption vessels arranged in parallel and containing adsorbent which adsorbs the strongly adsorbed gas more readily than the other components of the gas mixture. The process includes two evacuation steps and two or more purge steps.
