CO2 capturing using lime

flue gases of fossil-fuelled 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...

Sulfur Dioxide Scrubbers

An SO 2 scrubber system is the informal name for flue gas desulfurization (FGD) technology, which removes, or "scrubs," SO 2 emissions from the exhaust of coal-fired power plants A scrubber works by spraying a wet slurry of limestone into a large chamber where the calcium in the limestone reacts with the SO 2 in the flue gas There are some ....

Synthetic Gypsum

FGD units remove SO 2 from flue gas but, in doing so, generate large quantities of synthetic gypsum (FGD material), which is a mixture of gypsum (CaSO 4 C 2 H 2 O), calcium sulfite (CaSO 3), fly ash, and unreacted lime or limestone A number of power plants convert the CaSO 3 to calcium sulfate (CaSO 4) by forced oxidation and take appropriate ....
