Treatment of flue gas is to remove undesirable characteristics, like dust, soot, odor, and pollutants, like SOx, NOx, CO, H2S, from stack gas, resulting from combustion, in an environment friendly manner. Preferred method is packed or unpacked wet type scrubber, depending on the size of the plant and the chemicals used. Our system accepts using a wide variety of alcalines, especially wastewater, which will benefit in three ways. Firstly, acid not has to be added to wastewater to lower pH, because the acid produced during gas treatment will neutralize the wastewater. Secondly, operational costs for reagents of alkaline, which are used in conventional methods, are lowered. Thirdly, there will not be any solid waste production.
