SO 2 emission from lean waste gases in stationary sources (e.g., power plants) can be treated by wet and dry flue-gas desulfurization (FGD), while the stationary source like ore-smelting plants produces rich gases containing SO 2 of much higher concentration that need different control processes. Wet FGD technology

The power plants are facing more stringent environmental restrictions, especially after the implementation of new "air pollutant emission standards in coal-fired power plant" (GB13223-2011) in 2012 [1]. At present, in most coal-fired power plants in China, wet limestone–gypsum flue gas desulfurization (FGD) is most widely used.

Maintenance of Flue Gas Desulfurization (FGD) processes is an important part of power plant operations. Without desulfurization, flue gases can be filled with unacceptable levels of sulfur dioxide (SO2) emissions, that are in violation of EPA regulations. A common way to reduce these emissions is to employ wet scrubber operations, using hydrated lime (lime …

Wet flue gas desulfurization or scrubber systems are very effective in reducing sulfur dioxide (SO2) emissions caused by coal combustion boilers. The flue gas discharged from the boiler is fed into the absorber, where a mixture of water and pulverized limestone is sprayed on the flue gas. The limestone slurry reduces sulfur emissions by absorbing the …
