In a typical modern installation, the wet scrubber process is based on an aqueous slurry of lime (CaO) and limestone (CaCO3). Passing through the slurry, SO2 in the flue gas is removed, via a complex series of chemical reactions, to produce calcium sulphate (gypsum) and sulphite salts – what is known as the limestone gypsum process.
