ABSTRACT:
A cross over valve (46) cyclically supplies air from a compressor (30) to a first bed (48). The first bed contains a material, such as a 5 angstrom zeolite, which preferentially adsorbs nitrogen and passes oxygen and argon therethrough. The oxygen and argon mixture is passed to an oxygen/argon receiving reservoir (60). As the cross over valve flushes nitrogen from the first bed, a pumping fluid under pressure is fed into a pressurizing fluid receiving region (66) to pump the oxygen/argon mixture into a second bed (80). The second bed contains a material, such as 4 angstrom zeolite, which passes nitrogen and argon therethrough and which preferentially adsorbs oxygen. The argon, and the nitrogen if any, are discharged through a secondary gas outlet (22) and the oxygen is adsorbed. The adsorbed oxygen is drawn from the second bed by an enriched oxygen pump (90) and pumped periodically into an enriched oxygen storage reservoir (100).
