  • Patent number: 9951656
    Abstract: The invention relates to a method for operating a gas turbine system, wherein the gas turbine system includes a compressor, a combustor, a heat recovery steam generator, a scrubber, a direct contact cooler. The method includes 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.

  • Patent number: 9200805
    Abstract: An apparatus and method to recover heat from and cool flue gases. As shown in FIG. 1, a condenser 10 is provided having two packed beds (20/26) and separate condensate loops. The condensate loops are configured such that first packed bed 20 maximizes heat recovery from flue gas 12 and second packed bed 26 maximizes cooling of flue gas 12. Temperature differences between entry flue gas 12 and recovered condensate 38 are minimized while temperatures differences between exit flue gas 34 and return condensate 54 is also minimized.

  • Publication number: 20130098104
    Abstract: A gas cleaning system is operative for removing water vapour from a carbon dioxide rich flue gas generated in a boiler combusting a fuel in the presence of a gas containing oxygen gas. The gas cleaning system comprises a flue gas condenser (12) being operative for condensing water from at least a portion of the carbon dioxide rich flue gas generated in the boiler by bringing the carbon dioxide rich flue gas into contact with a circulating cooling liquid, thereby generating a cleaned carbon dioxide rich flue gas having a lower concentration of water vapour than the carbon dioxide rich flue gas leaving the boiler. The gas cleaning system comprises a heat pump (100) being operative for absorbing heat at a first temperature from the cooling liquid, and for desorbing heat at a second temperature, being higher than the first temperature, to a heat sink (124).
