Abstract
Pressure swing selective adsorption-desorption process and apparatus for separating at least one gaseous component from a gas mixture. After selective adsorption from the gas mixture, the subsequent desorption procedure comprises two separate steps which are carried out under different pressures. The desorbed gases obtained by the two separate desorption steps are then combined.
