ABSTRACT:
A method for the recovery of oxygen from air in which a high-temperature ion transport membrane system is integrated with combustion turbine system. Coproduction of oxygen and electric power is achieved in an alternative embodiment by integrating a combined cycle power generation system with an ion transport membrane system. The design performance of the gas turbine in the combined cycle system is maintained by controlled water injection into the membrane non-permeate stream, all or a portion of which optionally is introduced into the gas turbine combustor. Water can be introduced directly into the combustor air inlet. Alternatively, makeup air is added to the membrane feed to maintain the performance of the gas turbine. NOx formation is reduced by introducing the oxygen-depleted non-permeate from the membrane system to the gas turbine combustor.
