One of the most important applications of hydrochloric acid is in the pickling of
steel that is to remove rust or iron oxide scale from iron or steel before
subsequent processing, such as extrusion, rolling, galvanizing, and the others.
Technical quality HCl at typically 18% concentration is the most commonly used
pickling agent for the pickling of carbon steel grades.
Another major application of hydrochloric acid is in the production
of organic compounds, such as vinyl chloride and dichloroethane for PVC.Hydrochloric acid is often captive use,
consuming locally produced hydrochloricacid. Other organic compounds produced with hydrochloric acid include bisphenol A for polycarbonate, activated
carbon, and ascorbic acid, and a number of pharmaceutical products.
