FLUE GAS DESULFURIZATION (SCRUBBING) In a flue gas desulfurization (FGD) system, sulphur compounds are removed from the exhaust emissions of fossil-fuelled power stations. This is done by means of an industrial process through the addition of absorbents. Flue gas desulfurization can remove up to 95 % of the sulphur dioxide from the flue gas.
The calculation results of the desulfurization system for 300 MW utility in China by this model was compared to that of corresponding measured results. The simulation results agreed with the measurement results very well. The operation mode of boilers of power plant in China is different to that of other countries since variable coal property ...
Setting the SO 2 emission limit as 50 mg/m 3, the minimum desulfurization efficiency as 95%, the number of particles as 100, and the maximum iteration time as 50, the operating parameters, including the lime slurry pH, temperature, lime slurry density, and number of circulating pumps, were optimized.
Desulfurization is a technology used to separate SO 2 from its emitting sources such as exhaust flue gases of fossil-fuel power plants, oil refineries, etc. The crucial requirement to decrease sulfur loading in fuels to nearly zero content is imposed by mandatory environmental and health protocols as well as the accurate tolerance needed for their use in fuel applications.

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 SO2 contained in the flue …
