Flue Gas Desulfurization (FGD) Plant
All over the world, more than 75% of electricity is generated from thermal power plants and coal contains Sulphur in the range of 0.3%-1% depending upon the origin location. Whereas, in some regions, Sulphur content is up to 1.5%. In thermal power plants, Sulphur (present in coal) reacts and form Sulphur dioxide (SO2), which is very harmful to the environment. So to save our environment, many countries like the US and European countries have stringent regulations that the discharge of Sulphur dioxide (SO2) should be less than 0.05%. For this, power plants are installing Flue Gas Desulfurization Plants (FGD) or units.
Processes of Flue Gas Desulfurization (FGD) Technology: Limestone Scrubbing
- Limestone slurry is sprayed on the incoming flue gas. The Sulphur dioxide gets absorbed. The limestone and sulfur dioxide react as follows : CaCO3 + H2O + 2SO2 ----> Ca+2 + 2HSO3- + CO2
CaCO3 + 2HSO3- + Ca+2 ----> 2CaSO3 + CO2 + H2O - A process improvement called forced oxidation further oxidizes the calcium sulphatic to Calcium sulphate in the following reactions CaSO3 + H2O + 1/2 O2 ----> CaSO4 + H2O
