By adopting FGD, India's power plants would produce around 12–17 million tonnes of gypsum which can thus meet domestic shortfall and reduce the import burden. A number of steps need to be taken to ensure limestone availability and gypsum utilization. The Ministry of Environment, Forest and Climate Change (MoEF CC) should release guidelines for appropriate safeguards in handling, storage ...

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.
