Method of exhaust gas treatment for a gas turbine system and exhaust gas treatment assembly

An exhaust gas treatment assembly for a gas turbine system, wherein the gas turbine system includes a compressor for compression of inlet air, a combustor for combustion of a fuel gas with compressed inlet air to form an exhaust gas, the assembly comprising:

• a heat recovery steam generator for collecting a portion of the exhaust gas;
• a scrubber for scrubbing the fuel gas with a scrubbing fluid before it is fed into the combustor,
• a direct contact cooler for cooling the exhaust gas discharged from the heat recovery steam generator with a cooling fluid,
• wherein
• the scrubber is fluidly connected with the direct contact cooler in order to introduce the scrubbing fluid discharged from the scrubber into the direct contact cooler,
• the heat recovery steam generator is fluidly connected with the direct contact cooler in order to contact the fluid in the direct contact cooler with the exhaust gas discharged from the heat recovery steam generator to remove a portion of nitrogen oxide therefrom;
• the direct contact cooler is fluidly connected with the compressor to feed the exhaust gas discharged from the direct contact cooler into the compressor.
