Pressure swing adsorption with increased recovery of a highly adsorbable product gas component is carried out with a cycling in which, during the flushing phase, and at least over the latter portion thereof, the flushing gas has a concentration in the product gas component which is substantially equal to that of the product gas. To further increase the yield and the concentration of the product gas component in the product gas, the pressure in the absorber is reduced over a time period between the termination of the adsorption phase and the beginning of the desorption phase, with the effluent gas during this reduction in pressure being reused in the pressure swing adsorption cycle.
