ABSTRACT:
An improvement of a known pressure swing adsorption process for separating a desired gas from a gas mixture using a cylinder containing an adsorption column is disclosed. The improvement resides in a procedure for regenerating the adsorption column for repeated use, which comprises returning a portion of the desired gas having been separated in the cylinder back into the cylinder at an intermittently varying rate to flow through the column, to efficiently desorb a gas component having been adsorbed by the adsorption column and purge away the desorbed gas from the cylinder.
