Magnesium oxide is converted to magnesium sulfite and sulfate, which are removed from the solution and dried. The mixture of dried magnesium sulfite and magnesium sulfate is regenerated by calcining at about 1,825°F (Fink, 1992). The calcining operation produces magnesium oxide, which is returned to the absorption system and a sulfur-dioxide rich gas, which can be fed to a sulfuric acid plant or reduced to …
