Apr 11, 2021 Introduction. Flue gas desulfurization (FGD) is the removal process of sulfur dioxide (SO2) from flue gases. Sulfur dioxide in gases is produced by the combustion of fossil fuels and many industrial processes such as gasoline refining as well as cement, paper, glass, steel, iron and copper production.
The Flue-Gas Desulfurization (FGD) process utilizes a set of technologies to remove sulfur dioxide (SO 2) from the flue gas emissions of coal-fired power plants.FGD systems were developed as a response to the exhaust flue gases from fossil fuel-burning plants, principally coal-burning, that posed both an environmental and human health hazard.
