Steel Pickling: A Profile, Draft Report.
Steel pickling is part of the finishing process in the production of certain steel products in which oxide and scale are removed from the surface of strip steel, steel wire, and some other forms of steel, by dissolution in acid. A solution of either hydrogen chloride (HC1) or sulfuric acid is generally used to treat carbon steel products, while a combination of hydrofluoric and nitric acids is often used for stainless steel. Steel pickling and the associated process of acid regeneration result in the emission of hazardous air pollutants (HAPs).
