Introduction. Sulfur dioxide (SO 2) is one of the major pollutants contributing to frequent hazy weather in China.A large amount of SO 2 in the atmosphere comes from coal combustion. As the amount of coal for power generation accounts for 45% of the total coal consumption in 2015 (National Bureau of Statistics [NBS] Citation 2017), the Chinese …

What is Flue Gas Desulfurization (FGD)? FGD is a set of technologies used to remove Sulfur Dioxide (SO2) from exhaust flue gases in coal, oil-fired, and waste- to-energy power stations. SO2 is a pollutant/irritant in air and a major contributor in the creation of acid rain. SO2 emissions are subject to strict environmental protection regulations.
