Abstract:
1. A method of recirculating carbon dioxide from a flow of gas through a gas turbine engine comprising a compressor region upstream of a combustion means, a turbine region downstream of said combustion means and an exhaust nozzle downstream of said turbine region, the method comprising supplying air to the compressor region, supplying fuel to the combustion means, burning said fuel in the air in said combustion means to produce exhaust gases, extracting carbon dioxide from the exhaust gases from a first region downstream of the turbine region, supplying carbon dioxide depleted exhaust gases to the exhaust nozzle, condensing the extracted carbon dioxide and thereafter feeding the condensed carbon dioxide to a second region upstream of the combustion means without adding any constituent thereto, the second region comprising the compressor region.
