United States Patent Application

View the Complete Application at the US Patent & Trademark Office
Integrated gas turbine combustion engine and ion transport membrane system comprising a gas turbine combustion engine including a compressor with a compressed oxygen-containing gas outlet; a combustor comprising an outer shell, a combustion zone in flow communication with the compressed oxygen-containing gas outlet, and a dilution zone in flow communication with the combustion zone and having one or more dilution gas inlets; and a gas expander. The system includes an ion transport membrane oxygen recovery system with an ion transport membrane module that includes a feed zone, a permeate zone, a feed inlet to the feed zone in flow communication with the compressed oxygen-containing gas outlet of the compressor, a feed zone outlet, and a permeate withdrawal outlet from the permeate zone. The feed zone outlet of the membrane module is in flow communication with any of the one or more dilution gas inlets of the combustor dilution zone.
