The wet flue gas desulphurization has been the most widely used in the coal-fired power plants because of high SO 2 removal efficiency, reliability and low utility consumption. In this paper, laboratory studies on the removal of SO 2 from gas mixtures with a novel wet-type PCF device (Chinese LOGO) were reported, CaCO 3-in-water …

the FGD wastewater treatment plant. As mentioned, due to the high pollutant content of the FGD brine, it cannot be re-used elsewhere in the power station. The three stage treatment plant to be constructed will treat this wastewater and a produce a clean water stream that can be used as feed to the demineralized/potable water treatment plant.
