The flue gas desulfurization (FGD) plant removes sulfur dioxides (SO 2) from flue gas produced by boilers, furnaces, and other sources. Mitsubishi Power effectively contributes to the prevention of air pollution through its wet limestonegypsum FGD process and seawater FGD process, and both processes can treat a large range of SO 2 concentrations for greater plant reliability and economics.
