Abstract: 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 SO2,at the same
time generating a huge amount of flue gas desulfurization gypsum。This paper describes the physical
and chemical properties of natural gypsum and FGD gypsum，reviews 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.
