To remove the SO2, the flue exhaust from a coal-fired power plant is commonly bubbled through a mixture of lime or limestone and water. The resultant reaction typically captures 95 % or more of the SO2. Approximately 80-85 % of worldwide FGD units installed in power plants use wet limestone scrubbing vs. other technologies.

In both cases, limestone of suitable quality is used as sorbent, with limestone flour, of finer granulation, in the wet limestone method and limestone sand, of slightly coarser granulation, in fluidized bed boilers. In the semi-dry method of flue gas desulphurisation, the main type of sorbent is a quicklime [31,32].
