FGD Libsorption, It is an abbreviation for Flue Gas Desulfurization is a technology set that is used to remove sulfur dioxide (SO2) from the exhaust gases produced at fossil fuel power plants. The primary mandate of FGD systems is to cut down the environmental effects of SO2 emissions, which helps amount to acid rainruining crop lands and poisoning lakeswith nitrogen oxides for plants--not to mention its adverse effect on lung health. Technologically, FGD systems typically involve both the absorption of SO2 in liquid materials and the reaction of this with gases, often limestone slurry. The resulting mixture is gypsum, a byproduct used widely by the construction industry. FGD systems are equipped with spray towers, absorbers and slurry circulation systems to ensure efficient gas purification. The application of FGD desulfurization is widespread, included coal-fired power plants and Industrial Boilers. It delivers a key solution for environmental protection and creation of clear air law.
