Process for obtaining nitrogen from air or nitrogen-containing gases by

Process to obtain nitrogen from gas mixtures containing oxygen and nitrogen by using alternating pressure adsorption on carbon molecular sieves, which comprises an adsorption cycle and a desorption cycle, in which the desorption cycle--which may also include the pressure equalization step--includes an idle time, which amounts to between 20 and 80% of the total time of the desorption cycle, plus a correspondingly shortened desorption step, whereby the adsorber decompression line is completely opened at the beginning of the desorption step and is completely closed and kept tightly closed after the decompression to ambient pressure during the subsequent idle period.
