HCl ( Hydro Chloric Acid )

With major production starting in the Industrial Revolution, hydrochloric acid is used in the chemical industry as a chemical reagent in the large-scale production of vinyl chloride for PVC plastic, and MDI/TDI for polyurethane. It has numerous smaller-scale applications, including household cleaning, production of gelatin and other food additives, descaling, and leather processing.

10 uses of Hydrochloric Acid:

  • To 'pickle' steel. This is a process whereby rust and scale is removed from steel sheet or coil with the use of a dilute solution of Hydrochloric Acid. The metal can then be processed
  • To manufacture organic compounds such as Vinyl Chloride and Dichloroethane which are used to produce PVC (Poly Vinyl Chloride)
  • To regulate the pH level in a wide range of manufacturing and treatment processes including the production of drinking water, pharmaceuticals, beverages and foods
  • In the processing of additives for the food industry including fructose, citric acid and hydrolyzed vegetable protein
  • To produce inorganic compounds for water treatment including drinking water and waste water
  • To neutralise the water in swimming pools making it safe for bathers
  • To regenerate ion exchangers
  • To process leathers in the tanning industry
  • To purify common salt
  • In North Sea oil production where it is used to facilitate oil well acidizing
