Beschreibung
Zusammenfassung:	A method for operating a gas turbine engine unit with a compressor section operable by a O2-rich first working fluid and a turbine section operable by a O2-lean second working fluid, and a unit for an oxygen extraction process, the method including: discharging all O2-rich first working fluid of the compressor section from a compressor of the compressor section to the unit for the oxygen extraction process so that all O2-rich first working fluid of the compressor section is used for the oxygen extraction process, extracting O2 from the O2-rich first working fluid by an oxygen extraction process, cooling at least one wall of the at least one combustion chamber of the combustion section by the O2-rich first working fluid while bypassing the at least one combustion chamber and heating the O2-rich first working fluid while by-passing the at least one combustion chamber.
