Desulfurization In magnesium oxide (MgO) scrubbers the flue gas enters the scrubber and contacts the MgO slurry. The SO 2 is absorbed in the scrubber slurry and forms insoluble magnesium sulfite (MgSO 3) as in the equation below. MgO(s) + SO 2 (g) → MgSO 3 (s) Oxygen injected at the base of the scrubber further oxidizes the MgSO 3 to ...
