Flue-gas desulfurization Wikipedia

The process by which this synthetic gypsum is created is also known as forced oxidation: CaSO 3 (aq) + 2H 2 O (l) + ½O 2 (g) → CaSO 4 · 2H 2 O (s) A natural alkaline usable to absorb SO 2 is seawater. The SO 2 is absorbed in the water, and when oxygen is added reacts to form sulfate ions SO 4 and free H +. The surplus of H + is offset by the carbonates in seawater pushing the carbonate
