Zusammenfassung:	In a process for the production of oxygen by adsorption the combination of the following measures is used: … … the number of adsorbers is at least three; … the duration of pumping y at subatmospheric pressure during the stage b) is greater than the phase shift T/n and at least equal to the duration x of the production stage; … the stage of pumping of the adsorbent column is performed by applying to the said adsorption column successively at least two pumping systems, one operating starting at the onset of pumping, another adapted to operate until the end of the pumping. … ……
