In a pressure swing adsorption process, the adsorbent being for example a carbon molecular sieve, the usual initial surge of an undesired component, e.g., O2 in a nitrogen stream, from the outlet of a freshly repressurized adsorber, is reduced or eliminated by conducting repressurization in a stage-wise manner with the final part of the repressurization being conducted substantially more slowly than the initial stage of repressurization.
