Patent ID: 7363764

Claim:
A method of operating a gas turbine power plant comprising: compressing air in at least one compressor; feeding the compressed air from the at least one compressor through a first side of a membrane/partial oxidation reactor; feeding the air from the first side of the membrane/partial oxidation reactor to a combustion chamber; combusting the air with hydrogen thereby producing flue gases; expanding the flue gases in a gas turbine driving at least one generator ( 9 ); feeding natural gas mixed with steam to a second side of the membrane/partial oxidation reactor and converting the natural gas at least to H 2 and CO, whereby oxygen is transferred from the compressed air through a membrane of the membrane/partial oxidation reactor and oxygen is used for partial oxidation of the natural gas; feeding resulting syngas to a CO shift reactor thereby producing H 2 and converting a majority of remaining CO to CO 2 ; feeding the resulting syngas from the CO shift reactor to CO 2 removal equipment thereby removing CO 2 ; feeding the resulting syngas comprising H 2 and H 2 O from the CO 2 removal equipment at least to the combustion chamber.
