ABSTRACT:
This process uses a pressure variation cycle, in which, at at least one instant in the cycle, a terminal of a compression machine (1, 3) is switched from a first space (A1) which is at a first pressure P1 to a second space (A2) which is at a pressure P2 significantly different from P1. The switching comprises an intermediate operation in which the terminal is brought simultaneously into communication with the first space and with the second space. The process is useful in the production of oxygen from atmospheric air by adsorption.
