CO2 capturing using lime

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 carbonator (cover image). This part of the plant is a cir-culating fluidised bed reactor. This means that the flue gas is fed through a porous plate into a vertical cylinder ...

The Benefits and Effects of Limestone | Sciencing

A plant that burns coal spews sulfur dioxides into the atmosphere, which are a greenhouse gas. Limestone, applied as a slurry, which is a mixture of minutely crushed limestone and water, helps to prevent sulfur dioxide from escaping through the plant's smokestack. The limestone traps the sulfur dioxide gas in the wet slurry with calcium and oxygen and makes the pollutant a removable solid ...
