ABSTRACT:
A process for producing at least an oxygen product gas stream, and power from a gas turbine, by compressing a feed gas stream containing elemental oxygen and heating the feed gas stream on the retentate side of an ion transport reactor membrane section to produce a heated feed gas stream. Oxygen permeating the ion transport reactor membrane section is reacted with a first fuel gas stream to produce a first combustion products gas stream. The heated feed gas stream is separated using an ion transport separator membrane section having a retentate side and a permeate side into an oxygen-depleted gas stream on the retentate side and an oxygen-containing gas stream on the permeate side. At least a portion of the first combustion products gas stream can be recovered, and energy is extracted from at least one gas stream to be expanded in a gas turbine to produce energy.
