FLUE GAS DESULFURIZATION - Emerson Electric

2019-1-17 · What is Flue Gas Desulfurization (FGD)? FGD is a set of technologies used to remove Sulfur Dioxide (SO2) from exhaust flue gases in coal, oil-fired, and waste- to-energy power stations. SO2 is a pollutant/irritant in air and a major contributor in the creation of acid rain. SO2 emissions are subject to strict environmental protection regulations.
