ABSTRACT OF THE DISCLOSURE A process and and arrangement for converting air into a gaseous mixture enriched with nitrogen includes passing a first stream of air through an adsorber which preferentially adsorbs oxygen from the admitted first stream and thereby dis- charges a second stream of a gaseous mixture having a higher pro- portion of nitrogen as compared with the first stream. Control means are positioned in the second stream to measure the oxygen content of the continuously discharging second stream and termi- nates the discharge of the same when the oxygen content thereof exceeds a predetermined value. Residual amounts of gaseous mix- ture are then evacuated from the adsorber. An additional adsorber is connected with the first-mentioned adsorber to form a first stage with each adsorber being alternately charged with air in a cyclic- al operation. Additional stages are connected in series so that the effluent nitrogen-enriched gaseous mixture can be further en- riched to a final desired value. -1-
