Hydrochloric Acid: Production
built 634 days ago
Hydrochloric acid is ... used in many other production processes for organic chemicals. It can be used in the production of p-phenylenediamine, polycarbonate resins, bisphenol A, polyvinyl chloride resins, and ethanol (from ethylene).

Most of all hydrochloric acid is produced as a secondary product from production of e.g. PVC and sodium sulphate. Production of chemically pure hydrogen chloride is made through reaction of chlorine gas with hydrogen gas. The gas is absorbed in demineralised water. In Sweden hydrochloric acid is made with all these methods.

Neutralizing hydrochloric acid with limestone (CaCO3) produces calcium chloride. The largest use for calcium chloride is highway deicing with production dependent on weather conditions. Other uses include dust control, industrial processing, oil recovery, concrete treatment and tire ballasting. Calcium chloride is ... used in oil recovery products such as drilling muds and work-over/completion fluids.

It is ... known that when the hydrochloric acid production falls short the required amount necessary to maintain the acidity of the white cells and the acid-base balance becomes insufficient and hydrogen chloride eventually vanishes from the circulation. When hydrogen chloride disappears from the circulation some other acid must take its place immediately in order to maintain the pH of the circulating fluids. The acid wastes assume the role of hydrogen chloride in the blood chemistry. This is followed by an imbalance of the blood chemistry.

When early in the twentieth century the Leblanc process was effectively replaced by the Solvay process without the hydrochloric acid by-product, hydrochloric acid was already fully settled as an important chemical in numerous applications. The commercial interest initiated other production methods which are still used today, as described below. Today, most hydrochloric acid is made by absorbing hydrogen chloride from industrial organic compounds production.
