Abstract:
An oxygen separator for separating oxygen from a heated oxygen containing gas discharged from an expander exhaust of a gas turbine hot gas generator used to drive a power turbine, said oxygen separator comprising:a duct open at opposite ends and configured to be directly mounted between said expander of said gas turbine hot gas generator and said power turbine in an in-line relationship to receive said heated oxygen containing gas from said expander and to discharge an oxygen depleted gas to said power turbine;a plurality of oxygen-selective ceramic membranes for extracting said oxygen from said heated gas;said oxygen-selective ceramic membranes mounted within said duct so that said oxygen separates from said heated oxygen containing gas and collects within said oxygen-selective ceramic membranes and an external flow of said oxygen depleted gas forms within said duct; andmeans for recovering said oxygen from said oxygen-selective ceramic membranes.
