Dec 15, 2018 Flue-gas desulfurization is an absorption process by which sulfur dioxide in flue gas from fossil-fuel power plants and from the emissions of other sulfur-oxide-emitting processes can be controlled. SO 2 is removed from flue gases by a variety of methods, common ones being: Wet scrubbing using a slurry of alkaline sorbent, usually limestone ...

Exhaust flue gas is drawn from the boiler and forced into an absorber tower by a booster fan. Once inside the absorber tower, the gas flows upwards through a dense shower of lime or limestone slurry. The slurry absorbs the Sulfur Dioxide (SO2) in the flue gas. The absorption process converts the lime/limestone into Calcium Sulfite.

Flue gas Desulphurization A real challenge for Thermal

Flue‐gas desulfurization (FGD) is a process to remove SOx from exhaust flue gas using an alkaline reagent. Sulfur oxides (SOx) is a group of gas. Among them Sulfur Dioxide (SO 2) is important. Other gases in the group are much less common in the atmosphere. 95% of the SOx emitted from combustion of fossil fuel is sulfur dioxide (SO 2).

PROCESS DESCRIPTION. Flue gas ducts connect flue gas system to absorber and from absorber to stack. A series of dampers are foreseen to intercept flue gases and eventually to by-pass the absorber. In order to compensate the additional pressure drops, at the FGD plant inlet flue gases pressure is increased by means of a booster fan.
