Beschreibung
Zusammenfassung:	The invention relates to a method for operating a gas turbine system, wherein the gas turbine system comprises a compressor, a combustor, a heat recovery steam generator, a scrubber, a direct contact cooler, the method comprising: introducing the scrubbing fluid discharged from the scrubber into the direct contact cooler, contacting the scrubbing fluid in the direct contact cooler with the exhaust gas discharged from the heat recovery steam generator in order to remove a portion of nitrogen oxide therefrom; feeding the exhaust gas discharged from the direct contact cooler into the compressor. With the technical solution of the present invention, nitrogen oxide in the exhaust gas is reduced to a certain extent by means of used scrubbing fluid from the scrubber. This solution may improve the efficiency in reduction of nitrogen oxide with a simple and feasible manner. Fig.1
