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.
