Flue-Gas Desulfurization (“Scrubbers”)

The chemistry of desulfurization The liquid used to “wash” the flue gas is a water-based calcium solution. Limestone (CaCO3) is cheap and creates an alkaline environment in water: CaCO3 + H2O Ca++ + HCO3– + OH– This OH– radicals bind with SO 2 in solution to form a sulfur ion: SO2 + OH– HSO 3 – while water always dissociates a bit:
