Processes of Flue Gas Desulphurization (FGD) Technology: Limestone Scrubbing. Limestone slurry is sprayed on the incoming flue gas. The sulphur dioxide gets absorbed. The limestone and sulfur dioxide react as follows : CaCO 3 + H 2 O + 2SO 2----> Ca +2 + 2HSO 3-+ CO 2 CaCO 3 + 2HSO 3-+ Ca +2----> 2CaSO 3 + CO 2 + H 2 O
