Abstract
Pressure swing selective adsorption-desorption process for separating at least one gaseous component from a gas mixture. In the adsorption step, a starting gas mixture is introduced at a pressure lower than that of a purge gas and, after completion of the adsorption step, at least a portion of the effluent gas from an adsorption column under execution of a purge is introduced into the adsorption column which has just completed the adsorption step and is about to enter upon the purge step, thereby pressurizing the latter adsorption column.
