Today, more than 200 of our online process analysers have been installed worldwide to monitor chlor-alkali productions.
Chlorine ranks no. 7 on the list of the most commonly produced chemical substances. It is the basis for the production of numerous intermediate substances, which, in turn, are important feedstock materials in the petroleum, aluminum, paper and pulp, or pharmaceutical industries.
For instance, chlorine is used in the production of a staggering 80% of drugs.
Chlor-alkali process
By far the largest part – about 95% – of the chlorine produced globally is obtained via the chlor-alkali process. In this process, chlorine and caustic soda are produced via electrolysis of sodium chloride brine. Caustic soda is another crucial basic chemical which is used in many chemical processes. Three electrolysis methods are applied for the chlor-alkali process, using either a diaphragm or a mercury or membrane cell.
For the process to be as efficient as possible, the brine has to be free of impurities. This makes chemical analysis necessary.
