The system that uses catalyst to reduce and eliminate flue gas containing N2 and H2O very efficiently.
It decomposes the gas into clean air N2 and H2O by use of the reduction reaction of gaseous NH3 and NOx which are supplied through AIG installed upstream catalyst.

In Green Works, SCR system can be applied to not only NOx but also to the refractory materials such as dioxin, furans, Etc.

	The downstream of the incinerator for industrial, household waste.
	Nitric acid manufacturing plant
	Industrial boilers
	Power plant
	Furnaces

	High elimination rate
	Refractory materials such as dioxins and furans can be removed too
	A wide range of temperatures (200˚C ~ 550˚C)
	Competitive facilities

The most efficient way of eliminating NOx from HRSG, incinerators, furnaces, and boilers is the SCR. It is the most effective way to eliminate them. NOx gas flowing to catalyst layer reacts with NH3 gas, The reaction starts. That is, NOx and NH3 react to each other and turn into H2O and N2 gas, and ultimately are discharged as clean gas.

	In the case of high-dust configuration, the SCR reactor is installed right at the rear of the economizer, and this location becomes the front of the air pre-heater.
	The biggest benefit of this structure is the fact that there is no separate pre-heating required to insert gas into the SCR reactor. Generally, the inserted gas is 300-430°C.
	The basic advantage of a high-dust system is the low initial investment cost and the savings in operational costs.

	In this arrangement, the catalyst becomes placed in the rear of the electrostatic precipitator or the bag-filter.
	Since the gas at the rear of the electrostatic precipitator is inserted into the SCR reactor, extremely small particles of dust are inserted; on the other hand, a lot of SO2 is also inserted.
	Since the temperature of emission gas does not reach the reactive temperature of De-NOx Catalyst, in many cases it requires an extra temperature-raising system.

	This structure is widely being applied in Western Europe. Also, this is used for remodeling of the original generating facilities.
	The SCR facility is installed at the very rear of other emission gas treatment facility. (eg. At the rear of a precipitator or Desulfurization Facility (FGD))
	Since there is a very small amount of dust or SO2 in the emission gas, exposure of catalyst to catalyst toxin may be prevented.
	Since the temperature of emission gas does not reach the reactive temperature of De-NOx Catalyst, in many cases it requires an extra temperature-raising system.
