"PROCESS TO REMOVE OXYGEN FROM A GAS CHAIN OF FOOD CONTAINING ELEMENTARY OXYGEN AND AT LEAST ONE OTHER GAS TO PRODUCE A GAS CHAIN WITH RETENTION OF REDUCED OXYGEN CONTENT". Process for removing oxygen from a gaseous feed stream to produce a retained gaseous stream with decreased oxygen content by feeding the gaseous feed stream into a bulk oxygen separation system to remove oxygen to produce a product stream crude gas with decreased oxygen content and a first stream of oxygen-containing permeate effluent, and feed the stream of crude product with decreased oxygen content in a separator having a primary ion transport membrane to produce a second stream of permeate effluent and the trapped gas stream with decreased oxygen content. A reactive purge gas is added to react with a portion of the oxygen permeate through the primary ion transport membrane and to purge the permeate side of the primary ion transport membrane, and / or a recycle gas stream comprising at least a portion of a gas stream during the process is added to at least one of the other gas streams.
