PROCESS FOR SEPARATION OF A GAS MIXTURE BY PRESSURE SWING ADSORPTION AND PLANT FOR ITS IMPLEMENTATION

摘要

The invention relates to a process for separation of a gas mixture by pressure swing adsorption, in which a pressure swing cycle comprising a sequence of steps which define adsorption, decompression/regeneration and pressure rise phases is employed for the or each adsorber. The cycle furthermore comprises at least temporarily at least one step of isolating the adsorber (II; IV) during which the pressure variation in the isolated adsorber is recorded.
