Flue Gas Desulfurization Overview by BIRANCHI is a document available to read on EtoBox.
Flue gas desulfurization (FGD) is a technology used to remove sulfur dioxide from exhaust gases of power plants that burn coal or oil. The most common FGD systems use an alkaline sorbent like lime or limestone to react with the SO2 in spray towers or spray dryers. These systems can remove over 99% of SO2 from flue gases. FGD was first developed in the 1850s but saw widespread adoption in the 1970s due to environmental regulations limiting SO2 emissions.
