Advances in Utilization of Flue Gas Desulfurization Gypsum

A large number of coal-fired flue gas is the culprit that caused by air pollution and acid rain. Based on this reason, lime/limestone-gypsum wet flue gas desulfurization(FGD) process as the main desulfurization technology are used by most countries to control emissions of SO 2, at the same time generating a huge amount of flue gas desulfurization gypsumThis paper describes the physical and chemical properties of natural gypsum and FGD gypsumreviews the utilization of experience and research status and progress of FGD gypsum. Our country FGD gypsum problems in the application process is also pointed out.
