Agrium manufactures sulfuric acid that is used primarily as a raw material in the manufacture of phosphorus fertilizers, although some is also offered for sale. Sulfuric acid is used in the production of alum as well as the pulp and paper industry.
Air blows through a drying tower and feeds into a sulfur burner.
The molten sulfur and air burn to produce sulfur dioxide. The sulfur dioxide passes into a converter where it is further oxidized over vanadium oxide catalyst beds to form sulfur trioxide. Sulphuric acid is produced at the Redwater and Conda plants.
