Flue Gas Desulphurisation (FGD)

Flue-gas desulfurization (FGD) is a group of technologies used to remove sulphur dioxide (SO2) from the exhaust flue gases of fossil-fuel power plants as well as from the emissions of other processes that release sulphur oxide, including waste incineration, petroleum refineries, cement and lime kilns.

  • Flue-gas desulfurization (FGD) may remove 90% or more of the SO2 in the flue gases for a typical coal-fired power plant.

Common methods used for FGD
