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 Hand 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 COremoval equipment to mainly hydrogen.

Gas turbine power plant and method of operating the same

In a power generation plant having at least one gas turbine cycle with heat-recovery boiler () and at least one steam turbine cycle operated via the heat-recovery boiler (), the gas turbine cycle being designed to be semi-closed and essentially free of emissions and essentially comprising a compressor (), a combustion chamber () arranged downstream of the compressor (), a gas turbine () arranged downstream of the combustion chamber (), a heat-recovery boiler () arranged downstream of the gas turbine (), and at least one generator () coupled to the gas turbine (), modes of operation with the gas turbine cycle stopped and start-up using fresh air are made possible by first means () being arranged which alternatively or additionally allow hot gas to be fed into the hot-gas path () between gas turbine () and heat-recovery boiler (), and by second means () being arranged which alternatively or additionally allow exhaust gas to be expelled from the exhaust-gas path () downstream of the heat-recovery boiler ().
