Abstract

The present disclosure pertains to a system configured to generate oxygen including a compressor configured to intake and pressurize gas, an oxygen separation unit comprising a first sieve bed, a second sieve bed, and an input receiving the stream of gas from an output of the compressor. The oxygen separation unit generates an oxygen flow by separating oxygen from the stream of gas. A membrane module in fluid connection with an output of the oxygen separation unit is configured to purify the oxygen flow generated by the oxygen separation unit. A valve arrangement is configured to direct, periodically, at least some of the oxygen flow from the membrane module through the sieve beds to purge the sieve beds with retentate gas and exhaust such retentate gas. One or more processors control the valve arrangement, so as to control the oxygen flow and purging of the sieve beds.
