Abstract
A method of operating a gas turbine power plant and gas turbine power plant are disclosed wherein hydrogen for the combusting process is produced by feeding natural gas mixed with steam through a membrane/partial oxidation reactor and converting the natural gas at least to H2 and CO. Thereby oxygen is transferred from the compressed air through the membrane of the membrane/partial oxidation reactor and the oxygen is used for the partial oxidation process of the natural gas. The process is followed by converting the syngas in a CO shift reactor and a CO shift reactor to a CO2 removal equipment to mainly hydrogen.

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 H2 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 H2 and converting a majority of remaining CO to CO2;
- feeding the resulting syngas from the CO shift reactor to CO2 removal equipment thereby removing CO2;
- feeding the resulting syngas comprising H2 and H2O from the CO2 removal equipment at least to the combustion chamber.
A gas turbine power plant comprising:
- at least one compressor;
- a membrane/partial oxidation reactor comprising a membrane, the membrane/partial oxidation reactor connected proximate a first end of a first side of the membrane to the compressor;
- a combustion chamber connected to the membrane/partial oxidation reactor proximate a second end of the first side of the membrane;
- a gas turbine connected to the combustion chamber;
- a feed line connected to the membrane/partial oxidation reactor proximate a first end of a second side of the membrane;
- a CO shift reactor connected to the membrane/partial oxidation reactor proximate a second end of the second side of the membrane by a feed line;
- CO2 removal equipment connected to the CO shift reactor;
- and
- a feed line at least for hydrogen connected to the combustion chamber.
