Lime is typically used on large coal- or oil-fired boilers as found in power plants, as it is very much less expensive than caustic soda. The problem is that it results in a slurry being circulated through the scrubber instead of a solution. This makes it harder on the equipment. A spray tower is typically used for this application. The use of lime results in a slurry of calcium sulfite (CaSO

flue gases of fossilfuelled power plants can be made available for geological storage or further use, whereby the CO 2 is first bound using limestone and then released. As is usual, the flue gas from the power plant is first of all desulphurised in the flue gas desulphurisation (FGD) plant. It then comes into contact with lime (CaO) in a

The wet limestone gypsum process uses limestone as an absorbent for the desulphurization of flue gases and produces gypsum that is suitable for industrial use as an end product. The flue gases coming from boiler are directed into the absorber where the pollutants SO 2,HCl, HF are removed before flue gas is released into the atmosphere through the stack.
