Information @ a Glance

General

  • Hydrochloric acid is the solution of hydrogen chloride (HCl) in water.
  • HCl is a highly corrosive, strong mineral acid, and therefore has major industrial use. It is found naturally in gastric acid.
  • Historically called muriatic acid and spirit of salt, hydrochloric acid was produced from vitriol and common salt.
  • The physical properties of hydrochloric acid, such as boiling and melting points, density, and pH depend on the concentration or molarity of HCl in the acid solution.

Process

  • The hydrochloric acid produced at Kemira Kemi AB in Helsingborg is yellow. This colour needs to be removed to increase the market.
  • The hydrochloric acid production at Helsingborg is based on a reaction between sulphuric acid and potassium chloride in natural gas heated ovens.
  • Chlorine and hydrogen react exothermally to form hydrogen chloride gas.
  • Hydrochloric acid is also made during fluorination of chlorinated organic products to manufacture chlorofluorocarbons.

Applications

  • Hydrochloric acid is used in the chemical industry as a chemical reagent in the production of vinyl chloride for PVC plastic.
  • High-quality hydrochloric acid is used in the regeneration of ion exchange resins.
  • HCl has numerous smaller-scale applications, including the production of gelatin and other food additives, descaling agents and in leather processing.
  • Hydrochloric acid is a strong inorganic acid that is used in many industrial processes. The application often determines the required product quality.


Report

  • Hydrochloric Acid is imported mainly for use in laboratory purposes as reagent by some quality control laboratories in industries.
  • Aqueous solutions of hydrochloric acid, sulfamic acid and sulfuric acid of 2% concentrations were prepared with addition of IBIT corrosion inhibitor.
  • The rapid development of China's caustic soda industry and hydrochloric acid downstream sector has provided a good development and making hydrochloric acid production and consumption continuously maintain a steady development.
