Use of Weak Sulphuric Acid for Fertiliser Manufacturing

Summary

An ethyl manufacturer produces a range of fuel and oil additives, including a diesel ignition improver in its Sarnia operation. The process generates a by-product stream of about 9,000 tonnes per year of 45% to 75% sulphuric acid. A proportion of the acid is sold to a liquid fertiliser manufacturer near Sarnia.
