  • Sulphuric acid is clear, colourless or brown oily liquid that is highly corrosive. Sulphuric acid is a very important chemical worldwide and over one million tonnes of sulphuric acid are made in the UK each year.
  • The raw materials required to manufacture sulphuric acid are air and sulphur. 
  • Sulphuric acid is made by burning sulphur. The sulphur dioxide given off is then reacted with a catalyst at high temperature to give sulphur trioxide. This can then be absorbed to give the acid. Depending on its intended use, it can be further diluted with water. This method of manufacture is called the Contact Process.
  • The Topsøe WSA process is highly suited for treatment of sulphur containing gases with a wide range of concentration of the sulphurous gas, ranging from a few tenths of percent to strong gases. The process also accepts process gas containing appreciable content of water that does not need to be dried prior to processing. The process is extremely flexible and adapts to large variations in feed gas flow and in concentration of the sulphurous compounds.
  • Sulfuric acid (H2SO4) is a basic raw material used in a wide range of industrial processes and manufacturing operations. Almost 70 percent of sulfuric acid manufactured is used in the production of phosphate fertilizers. Other uses include copper leaching, inorganic pigment production, petroleum refining, paper production, and industrial organic chemical production.
  • The largest use of sulphuric acid is in the production of phosphate fertilisers. It is also used as an acidic dehydrating agent in petrochemical processes and oil refining, and to make hydrochloric and hydrofluoric acids, aluminium and copper sulphate and chromium compounds.
  • It is also used in making organic products, refining petroleum, making paints and pigments, processing metals, and making rayon. One of the few consumer products containing sulphuric acid as such is the lead storage battery, found in cars.
  • Agriculture and metals processing are the two hottest markets for sulfuric acid right now. Roughly 60% of sulfuric acid produced goes into agriculture, primarily in the manufacture of phosphate fertilizers.
  • Sulfur and sulfuric acid will continue to be important in agricultural and industrial applications, although consumption will be less than production. Because sulfuric acid consumption for phosphate fertilizer production was expected to increase at a lower rate than some other uses, phosphate may become less dominant in sulfur consumption but remain the leading end use.
  • Sulfuric acid is a corrosive chemical and can severely burn the skin and eyes. It may cause third degree burns and blindness on contact. Exposure to sulfuric acid mist can irritate the eyes, nose, throat and lungs, and at higher levels can cause a buildup of fluid in the lungs . Asthmatics are particularly sensitive to the pulmonary irritation. Repeated exposures may cause permanent damage to the lungs and teeth. The International Agency for Research on Cancer has classified 'occupational exposures to strong-inorganic-acid mists containing sulfuric acid' as carcinogenic to humans.
  • World consumption of sulphuric acid has risen from $4.5 billion in 1992 to $5.4 billion in 2000. Japan, Canada and Germany are the leading exporters.
  • The importance of pyrites to the world sulfur supply has significantly decreased; China and Finland were the only countries of the top producers whose primary sulfur source was pyrites. About 80.0% of pyrite world production was in China. Sulfur and sulfuric acid will continue to be important in agricultural and industrial applications, although consumption will be less than production. Because sulfuric acid consumption for phosphate fertilizer production was expected to increase at a lower rate than some other uses, phosphate may become less dominant in sulfur consumption but remain the leading end use.
  • World sulphur production in 2005 totalled 71.4 million tonnes S/S-equivalent . Around 90% of global sulphur demand is for the production of sulphuric acid, the world’s most widely produced and used inorganic chemical. In 2005, we estimate that sulphuric acid output totalled almost 193 million tonnes H2SO4. The product is extremely versatile and has hundreds of uses. Major sulphur producers include the USA, Canada, Russia, Kazakhstan, China, Japan, Germany, Saudi Arabia, which account for 65% of global volume.
