<p>A pressure swing adsorption process conducted with plural cyclically reversible adsorbers, each of the adsorbers undergoing identical switching cycles. The switching cycles include sequentially at least one adsorption phase, at least two expansion phases, at least one desorption phase employing a purge gas which is foreign and inert relative to the material adsorbed in the adsorbent phase, a displacement phase employing a gas obtained from an expansion phase of one of the adsorbers to displace the purge gas, and at least one pressure build-up phase.</p> |
