USING LIME FOR FLUE GAS TREATMENT

DRY LIME SCRUBBING: In dry scrubbing, lime is injected directly into flue gas to remove SO 2 and HCl. There are two major dry processes: "dry injection" systems inject dry hydrated lime into the flue gas duct and "spray dryers" inject an atomized lime slurry into a separate vessel.

Flue Gas Treatment | Lhoist - Minerals and lime producer

The lime slurry serves a double function: to condition the flue gas by increasing humidity and to reduce the temperature. It also guarantees dispersion of calcium hydroxide in fine particles once the droplets are dry. The latent heat in the treated gas evaporates the water in the lime slurry and creates a liquid-gas reaction, leaving a dry powder.
