A process and apparatus for separating the components of a gas mixture in a pair of adsorption vessels using a single gas compressor/ pump to move gas into and out of the adsorption vessels. The cycle is such that the gas compressor/pump is in continuous operation. The adsorption cycle is non-symmetrical in that the se ries of steps carried out in one of the adsorbers is not the same as the series of s teps carried out in the other adsorber. The apparatus includes an intermediate gas storag e container which is used to temporarily store gas removed from the nonadsorbe d gas outlet end of the adsorption vessels so that it can be used to partially pre ssurize the adsorption vessels upon completion of the adsorbent regeneration step of the adsorption cycle.
