Before the flue gas reaches the absorber tower, it passes through a heat exchanger. The purpose of the heat exchanger is to cool the flue gas into the FGD to 90 degrees C. This heat is then used to reheat the cooled, treated flue gas as it passes back through the heat exchanger where it is reheated to above 80 degrees C to give it the buoyancyFile Size: 82KB. Sulfur removal | Flue gas desulfurization (SNOX™) The sulfur is recovered as commercial grade concentrated sulfuric acid and the nitrogen oxides are reduced to free nitrogen. The process is based on catalytic reactions and does not consume water or absorbents. Flue gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO 2) from exhaust flue gases of fossil-fuel power plants, and from the emissions of other sulfur oxide emitting processes. 7. Flue gas desulfurization 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 Citrate Process for Flue Gas Desulfurization, report, ; Washington by: 5. A process for flue gas desulfurization (FGD) with simultaneous polymeric ferric sulfate (PFS) production was investigated, using a ferrous sulfate (FeSO4) solution as the absorbent, sulfur dioxide.
( Mt) of Gas analysis procedures applicable to flue gas desulfurization by the citrate process book CCPs consisted of gypsum from flue gas desulfurization (FGD).
The desulfurization process uses wet scrubbers and forced oxidation to reduce SO 2 emissions, and the gypsum produced is mineralogically identical to natural gypsum (CaSO 4?2H 2O), making FGD gypsum an ideal replacement for the mined gypsum used to manufacture wallboard.
The citrate process proved capable of absorption of greater than 90% of the SO2 from the flue gas with ultimate conversion to elemental sulfur. However, in order to overcome problems that severely restricted process ontime, demonstration plant modifications were made that resulted in lower SO2 absorption--generally 50% to 70%.
Other articles where Flue gas desulfurization is discussed: air pollution control: Flue gas desulfurization: of an absorption process called flue gas desulfurization (FGD). FGD systems may involve wet scrubbing or dry scrubbing.
In wet FGD systems, flue gases are brought in contact with an absorbent, which can be either a liquid or a slurry of solid material.

In the case of the normally used absorption additive lime, the oxidation of S(IV) is an essential step in quantitatively producing the final product, gypsum (CaSO 4 - 2H 2 O).
Beside detoxication of S(IV) the dewatering properties of gypsum are improved when a high oxidation yield is achieved.
