Hydrochloric Acid

Hydrochloric Acid is a clear, slightly yellowish and steaming liquid, with a strong and unique odor. Its concentration (in weight) is approximately 32% (industrial grade) and 37% (TA/laboratories grade). It is sold in bulk and transported in duly lined tanker trucks.

Manufacture Process: Cubatão Plant

Hydrochloric Acid is formed when Chlorine and Hydrogen are burnt, both of which are generated by brine electrolysis. After combustion, the resulting Hydrogen Chloride (gas) is absorbed in water. At that point, Hydrochloric Acid with an approximate concentration of 32% can be obtained.

This process is called Synthesis Process.

Manufacture Process: Santo André Plant

Hydrochloric Acid is obtained when burning organochlorinated compounds generated in Dichloroethane production process, transforming them into Hydrogen Chloride, carbon dioxide and water. Combustion gases are eliminated to produce Hydrochloric Acid.

This process is called Thermal Oxidation.


Water and sewage treatment coagulants manufacture:

  • Chlorides (fertilizers/agrochemicals) and chemical intermediates manufacture.
  • Chemical processes in the general industry (oil extraction, acid fission/biodiesel, starch and protein hydrolysis, pH correction).
  • Metal surfaces striping – steel and metallurgical industries.
  • It is also used in mineral flotation and processing, ion-exchange resins regeneration, effluents neutralization, acidic activation of clays, hydrolysis of cellulose, etc.
