In a flue gas desulphurisation system (FGD), 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. This can remove up to 95 % of the sulphur dioxide from the flue gas, since the current threshold value for SO 2 in the EU is 200 …
Flue gas desulfurization (FGD) is a very common method for gas claning adopted in a gas processing plant. In this process, the flue gas with acid vapors is scrubbed to remove it as a by-product. Most of the FGD processes use alkali to scrub the flue gas. Many designers of FGD adopt the limestone gypsum process.

The desulfurizing agent (slaked lime powder) is injected into the bed to react with the SO 2 in the flue gas in order to achieve desulfurization. The purified flue gas is then discharged from the top of the fluidized bed. The two gas-solid phases are separated by a cyclone separator and other gas-solid separation devices.

The major bottleneck in SO 2 desulfurization from flue gas is the constituents of the flue gas itself. A typical flue gas from coal-firing plant with medium to high sulfur content has 75–80 vol% N 2, 12–15 vol% CO 2, 1800 ppm SO 2, 500 ppm NOx, 5–7 vol% H 2 O, 3–4 vol% O 2, < 100 ppm CO, and 10–20 mg Nm −3 of …
Flue gas desulfurization is commonly known as FGD and is the technology used for removing sulfur dioxide (SO 2) from the exhaust combustion flue gases of power plants that burn coal oroil to produce steam for the turbines that drive their electricity generators.

The flue gas desulfurization solids in the dry process (D-FGDS) are the newly formed CaSO 4 and the unreacted excess of CaO. They are carried along with the coal FA out of the boiler, forming the end product (FA + D-FGDS), which is highly alkaline due to the excess of CaO with respect to the initial SO 2 (Ca:S = 2.5–3.1). Due to a low ...
