Acid Reign: Sulfuric acid and oleum production.
Sulphuric acid is the most widely produced compound in the chemical industry. 200 million tonnes of sulphuric acid are produced globally each year, which is more than any other manufactured chemical. It plays an integral role in the production of nearly all manufactured goods, including fertilizers, synthetic detergents, dyes and pigments, explosives, and drugs. 60% of the sulfuric acid production around the world is used for the production of phosphoric acid. Phosphoric acid is further used to manufacture phosphate fertilizers and trisodium phosphate.
Alkylation units in oil refining processes also use sulfuric acid to produce high-octane components for gasoline blending. Since sulphuric acid is a relatively dangerous and expensive chemical to transport, most industries prefer to ship sulphur to site and produce their own sulphuric acid. While the capital cost may be higher, the long term economic and safety benefits make sulphuric acid plants attractive to industrial operations.
