reaction to lime powder

Slaked Lime (Calcium Hydroxide) | Carmeuse

Hydrated lime also called slaked lime is produced when water is added to calcium oxide (CaO, or quicklime). The result of this mixing of water and calcium oxide (quicklime) is an exothermic reaction known as slaking. The slaking reaction produces calcium hydroxide, (Ca (OH) 2 ). Initially, the calcium hydroxide is produced as a fine dry powder.

Lime in Flue-gas Treatment | Graymont

The acidic gases, normally SO 2 and HCl, are absorbed into the water where they chemically react with the lime and limestone. The resulting products, primarily calcium sulfite, can then be oxidized to produce calcium sulfate, a salable gypsum byproduct. There are three basic types of dry FGD processes.
