Title: Oxygen separator designed to be integrated with a gas turbine and method of separating oxygen

Abstract: An oxygen separator and method for separating oxygen from a heated oxygen containing gas that employs oxygen-selective ceramic membranes of elongated, tubular configuration within a duct for separation of oxygen from a heated gas. The duct can be attached between the exhaust of a gas turbine and a power generator driven by the exhaust or can be connected to one or more burners of a gas turbine. Supplementary compressed feed air may be added at a flow rate at least equal to that of the permeated oxygen for cooling and flow balancing purposes. A purge stream can also be introduced. Additionally, combustor tubes fabricated from an oxygen-selective ceramic membrane material may also be provided to produce combustion products that in turn can be used as a purge for downstream oxygen-selective ceramic membranes.
