A process for producing and oxygen gas stream, an oxygen-enriched gas stream, or a reaction product stream as a permeate stream and an oxygen-depleted retentate gas stream by first separating oxygen from a feed gas stream and thereafter cooling at least the permeate stream. The production and cooling of the permeate stream occurs within a single apparatus having at least one ion transport membrane.

[ What is claimed is:] [1.] A process for producing an oxygen gas stream or oxygen-enriched gas stream and an oxygen-depleted gas stream by first separating oxygen from a feed gas stream containing elemental oxygen and thereafter cooling the oxygen gas stream or oxygen-enriched gas stream obtained therefrom, within a single apparatus, the apparatus having a separator section and a cooling section and an oxygen product exit port, wherein the separator section includes an ion transport membrane having a retentate side and a permeate side, said process comprising:(a) compressing the feed gas stream;(b) dividing the compressed feed gas stream into a major gas stream portion and a minor gas stream portion;(c) heating the major gas stream portion;(d) introducing the heated major gas stream portion into the separator section of the apparatus;(e) introducing the minor gas stream portion into the cooling section of the apparatus near the oxygen product exit port;(f) removing oxygen from the heated major gas stream portion through the ion transport membrane of the separator section to obtain a hot oxygen-enriched gas stream on the permeate side of the membrane and an oxygen-depleted gas stream on the retentate side of the membrane; and(g) transferring heat from the oxygen-enriched gas stream to the minor gas stream portion to produce the oxygen gas stream or the oxygen-enriched product gas stream and a heated minor gas stream portion,wherein the minor gas stream portion either exits the apparatus or is combined with the heated major gas stream portion before the heated major gas portion is introduced into the separator portion of the apparatus, and wherein the oxygen-depleted gas stream exits the apparatus.
