US 2014/0230401 A1 · CYCLE TURBINE ENGINE POWER SYSTEM

Abstract

Disclosed is a semi-closed cycle turbine engine power system, operating with air, enriched air, or oxygen as the oxidizer, is made non-emissive via the semi-closed cycle, in a manner which produces saleable CO2 product at pressure. In an embodiment of the present disclosure, the system includes, among other elements, an oxidizer supply subsystem for producing an oxidizer and a turbine engine. The oxidizer supply subsystem provides at least a portion of the oxidizer produced by the oxidizer supply sub-system to a main compressor stage of the turbine engine. A fuel supply system is also included for providing fuel to turbine engine. Operation of the turbine engine produces power and an exhaust gas. At least a portion of the exhaust gas is recirculated via a recirculation subsystem to the main compressor stage of the turbine engine.
