ABSTRACT:
A method of separating oxygen from an oxygen containing stream in which compressed and heated oxygen is introduced into cathode side of an oxygen transport membrane reactor. Oxygen is permeated from the cathode side to the anode side. Motive fluid that is introduced into an ejector draws an oxygen permeate containing stream from the anode side at a subatmospheric pressure to form an oxygen containing product stream. The motive fluid, which can be steam raised by combustion used in heating the reactor, can be separated from the oxygen containing product stream to form an oxygen product stream. The use of an ejector lowers the partial pressure of the oxygen at the anode side of the membrane reactor and therefore the degree to which the oxygen containing stream need be compressed.
