NATURAL GAS COGENERATION SYSTEM

PURPOSE:To provide a natural gas cogeneration system with NOx content of combustion exhaust gas reduced, by introducing the exhaust gas to an NOx selective reduction catalyst, introducing rich gas to the pre-stream of catalyst for mixing with the exhaust gas, and conducting NOx reduction upon the ca...

Zusammenfassung:	PURPOSE:To provide a natural gas cogeneration system with NOx content of combustion exhaust gas reduced, by introducing the exhaust gas to an NOx selective reduction catalyst, introducing rich gas to the pre-stream of catalyst for mixing with the exhaust gas, and conducting NOx reduction upon the catalyst for accomplishment of purification. CONSTITUTION:Part or the whole of a natural gas as fuel is pressurized by a fuel compressor 1 and separated by the pressure swing adsorption method into a fuel with the methane concentration heightened and a rich gas in which hydrocarbons having carbonic numbers three or more are concentrated, and a turbine 3 is driven by the combusted and expanded fuel with methane concentration heightened, in case all natural gas as fuel is subjected to the separation process, and by the combusted and expanded mixture of the fuel with methane concentration heightened and the remainder of the natural gas in case part is subjected to the separation process. The exhaust gas is sent through the exhaust gas line and introduced to a NOx selective reduction catalyst layer 6 containing transition metal, and rich gas is introduced to the pre-stream of the catalyst layer 6 and mixed with the exhaust gas, and the NOx reduction is conducted upon the catalyst 6 to accomplish purification.
