Apr 15, 2017· 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 molten sulfur delivered pipes are also jacketed with steam to ensure the molten state of sulfur.

Converting the sulphur trioxide into sulphuric acid. This can't be done by simply adding water to the sulphur trioxide the reaction is so uncontrollable that it creates a fog of sulphuric acid. Instead, the sulphur trioxide is first dissolved in concentrated sulphuric acid: The product is known as fuming sulphuric acid or oleum.

Production. It is made by reacting sulfur trioxide with sulfuric acid to produce oleum. Then oleum is dissolved in water to produce more sulfuric acid. The sulfur trioxide is produced by burning sulfur to produce sulfur dioxide, which was then oxidized to sulfur trioxide with a catalyst. This process is called the contact process.

This report presents the economics of Sulfuric Acid production from sulfur in the United States. In this process, sulfur is burned to form sulfor dioxide, which is then converted to sulfur trioxide. Sulfor trioxide is converted to sulfuric acid by doublecontact double absorption (DC/DA) with a high concentration sulfuric acid solution in water.

Production of Sulfuric Acid There are two major processes (lead chamber and contact) for production of sulfuric acid, and it is available commercially in a number of grades and concentrations. The lead chamber process, the older of the two processes, is used to produce much of the acid used to make fertilizers; it produces a relatively dilute acid (62%–78% H 2 SO 4 ).
