Design & Development of Wet Ball Mill (WBM) for Flue Gas Desulfurization (FGD)

Flue Gas Desulfurization is a technique for reducing sulphur emissions, which cause acid rain. When fossil fuels are burned, large amounts of gaseous sulphur oxides are released into the atmosphere. Sulphur dioxide is a serious pollutant that has a negative impact on human health. Sulphur dioxide concentrations in the atmosphere can have an impact on the flora and wildlife. Furthermore, SO2 emissions serve as a precursor to acid rain and airborne particulates. Particulate matter is made up of very minute solid particles and liquid drops that contribute to the smoky look of exhaust gases. SO2 is removed from flue gas in practically all FGD systems by reacting with an alkaline material to create sulphite or sulphate. The contact method is used in the FGD process.
