ABSTRACT:
A molecular sieve bed container provides a plurality of molecular sieve bed chambers. The chambers are formed by tubular wall members concentrically located within a tubular outer housing and are closed at their ends by end closure members. One end closure member incorporates valves (not shown in FIG. 1) for controlling supply of charge gas to the sieve bed chambers and venting of purge gas from the sieve bed chambers. The other end closure member incorporates valves for controlling passage of product gas from the sieve bed chambers to an outlet (not shown) and portways for permitting some of the product gas to flow back through the sieve bed chambers as purge gas during a purge/vent phase. In the illustrated embodiment three sieve bed chambers are filled with a molecular sieve material which is given to removal of nitrogen from air supplied to the container as charge gas while two chambers are filled with a molecular sieve material which is given to removal of oxygen whereby supplies of oxygen-enriched air and nitrogen-enriched air are delivered as product gases.
