Sulfuric Acid World

Melting Sulfur  Sulfur Ore Sulfur Melting is  the first step of the production of sulfuric acid . Sulfur Actually, most of the elemental sulfur used for the production of sulfuric acid is a by-product of natural gas and petroleum refining. These by-products contain mainly 99.9% sulfur. The main impurity is carbon from natural gas or petroleum. Sulfur melting point is 115-120 0 C, depending on the crystal structure. It is melted with pressurized steam pipes easily. Viscosity The main features of the sulfur viscosity could be explained as follows: (i)                 minimum viscosity is at 160 0 C (ii)              10,000-fold viscosity increase just above 160 0 C. Sulfur burners, the second step of the production of sulfuric acid, are fed with 140 0 C molten sulfur, near the viscosity minimum, under the steep viscosity increase. Sulfur temperature is maintained by circulating 150 0 C steam through steam pipes around molten sulfur storage tanks and all m

 Sulfuric Acid,  H 2 SO 4 Sulfuric Acid Introduction ·         Sulfuric acid ( with the chemical formula H 2 SO 4 ) is an extremely corrosive strong mineral acid with molecular weight 98.079 g/mol. ·          it's generally noted as the “king of chemicals” as a result of it's made worldwide in such massive quantities. The use of acid has been taken as one index of the technical development of a state. ·         It's a colorless, odorless, very corrosive liquid that's soluble in water at all concentrations. ·          The historical name of this acid is Oil of Vitriol .  Concentrated acid has a very strong affinity for water. it's typically used as a drying agent and may be used to dehydrate several compounds. History Sulfuric acid was known as " oil of vitriol " as a result of it absolutely was produced by roasting "green vitriol" (iron(II) sulfate) in an iron retort. Within the 17 th century, chemist Joha
