Flue gas desulphurisation

Flue-gas desulphurisation

 

Flue gas desulphurisation (FGD) is the process used to remove sulphur dioxide (SO2) and other harmful acidic pollutants from the exhaust flue gases of coal-fired power plants.

Tarmac Buxton Lime is the UK’s leading supplier of High Purity Limestone (HPL) for flue gas Desulphurisation. Our limestone is ground and slurried with water, before being sprayed into a flue-gas scrubbing vessel. It reacts with acidic pollutants, turning them into solid particles that are removed using a dust collector.

This process is highly efficient with over 95% of sulphur dioxide being removed from the gas stream. The by-product, calcium sulphate or FGD gypsum as it is commonly known, can be recycled and reused in various different ways. These include the manufacture of plasterboard, plaster and cement, and production of domestic and agricultural fertilizers.
