ABSTRACT:
A process is provided for recovering oxygen from an externally fired power generating gas turbine system in which a hot, compressed air stream from a compressor to be expanded through a turbine expander to generate power is first passed over the feed side of a solid electrolyte membrane selective to the permeation of oxygen over other components of the air while a positive oxygen ionic potential is maintained on the membrane to separate oxygen from the stream, and removing the oxygen from the permeate side of the membrane before the residual air is expanded through the turbine expander to generate power.
