Sulphuric Acid
Sulphuric acid is the most widely used chemical in the world. The major use of sulphuric acid is in the production of phosphoric acid, which is used to manufacture phosphate fertilizers. Oxbow trades, distributes and handles the logistics and marketing of this commodity, ensuring a regular off-take for producers and a reliable source of competitively priced products for our customers.
Sulphuric acid is a ubiquitous chemical - meaning it appears everywhere in chemical manufacturing. It is used in a number of important markets, notably in the production of fertilizers and in the mining of precious metals. It is used in a variety of chemical applications, including the production of steel, paper, sugar, gasoline, and in water purification. Sulphuric acid reacts with water and organic materials. It is virtually colorless and odorless. Oxbow has specialized trucks, railcars, transloaders, and other purpose built equipment necessary for the safe and environmentally friendly transportation of sulphuric acid.
A large percentage of the world`s commercial sulphuric acid is manufactured in the Contact Process, and is available commercially in a number of grades and concentrations. In the Contact Process the acid supply comes from the burning of sulphur to form sulphur dioxide, which is then heated and passed over a catalyst; the sulphur dioxide is oxidized to sulphur trioxide. Concentrated sulphuric acid is used to dissolve sulphur trioxide where it forms oleum in an absorption tower. The oleum is then mixed with water to obtain concentrated sulphuric acid. Oxbow has longstanding relationships with the world`s leading sulphuric acid producers in Asia, Europe, and North America.
