摘要
The invention provides an emission control system for treatment of an exhaust gas stream of an engine, including an engine producing an exhaust gas stream; an SCR catalyst unit downstream from the engine and in fluid communication with the exhaust gas stream; and an ammonia generation system comprising a reservoir containing ammonium hydroxide and an ammonia injector, wherein the reservoir is in fluid communication with the ammonia injector and the ammonia injector is in fluid communication with the exhaust gas stream upstream of the SCR catalyst unit. A method of treating an exhaust gas stream of an engine is also provided, including the steps of heating ammonium hydroxide to produce gaseous ammonia and transferring the gaseous ammonia through an ammonia injector into the exhaust gas stream such that the gaseous ammonia disperses within the exhaust gas stream upstream of a SCR catalyst unit.
