The Flue Gas Desulfurization (FGD) systems including ones that are installed in the worlda Ca minig mills. These systems are made essentially to cut back the poisonous ambiance of sulfur dioxide ( SO2 ) in industries. Many sulphur recovery processes are driven by the main raw material gypsum, which was traditionally linked to a flue-gas desulphurisation ( FGD ) system. The main feature of this system, in practical terms, is that slurry containing lime stone powder ( limestone ) is sprayed into absorber towers, absorptingS02 on the surface of the limestone particles Such that any SO2 thought to have escaped scrubber would have been reacted away The conditions for oxidation in this process are so benign that with only a few grams of catalyst it can already double system efficiency. The system has been widely applied in power plants, cement production factories andall types of industries with high sulfur dioxide emissions. User-friendly and efficient, tnere are few negative comments from customers who have purchased this product. This series system meets environmental standards while providing a sustainable means of controlling air pollution.
