ABSTRACT:
A separation process, involving an adsorber containing at least one adsorbent with an inlet and outflow, involves the following stages of the cycle:--stage I, repressurization from the low pressure of the cycle;--stages II and III during one of which the high pressure of the cycle is reached; and stage IV, depressurization/purging, during which the low pressure of the cycle is reached. Each stage (I to IV) involves a fixed gas flow (F) at one end of the adsorber and a free gas flow (.lambda.) at the other end of the adsorber, the fixed flows (F) addressing the inlet (E) and outlet (F) ends of the adsorber from one stage (I to IV) to the next. The process is particularly applicable to the production of oxygen from air.
