The present invention relates to a method for processing nitrogen oxide among exhaust gas of an LNG gas turbine combined thermoelectric power plant and, more specifically, to a method for processing nitrogen oxide among exhaust gas of an LNG gas turbine combined thermoelectric power plant by using precious metal oxidation catalytic reduction such as platinum and selective catalytic reduction. In a method for denitrifying exhaust gas of the gas turbine cogeneration plant comprising a platinum oxidation catalyst, a selective reduction catalyst, and ammonia injection equipment, and using LNG as fuel, the amount of the platinum catalyst used is a small amount as much as 1/10-1/60 of the selective reduction catalyst, the oxidation catalyst is installed in the front of the space such as an ammonia injection grid (AIG), the AIG is installed in the area of 400-450°C temperature, and the selective reduction catalyst is installed by being divided into several partitions between heat collecting equipment in the area of 180-310°C temperature of the HRSG inner space. |
