Flue Gas Desulphurisation Plant

Flue Gas Desulphurisation Plant

Flue Gas Desulphurisation Plant Purpose The Flue Gas Desulphurisation (FGD) plant removes Sulphur Dioxide from the flue gas before it is released into the atmosphere and hence reduces our impact on the environment. This technology enables Ratcliffe to use British coal. British coal tends to have high sulphur content so burning it causes sulphur dioxide to be released. The FDG technology ...
