The Manufacture of Sulfuric Acid and Superphosphate

The molten sulfur is filtered to remove any impurities (usually iron or organic compounds). Lime is added to reduce the acidity of the molten sulfur therefore reducing its corrosivity. The molten sulfur is pumped to the burner where it is burnt in an excess of dry air. The gas exiting the burner is maintained at 8 - 9%v/v sulfur dioxide and
