6. Other processes for obtaining chlorine
Among the processes for recycling HCl into chlorine, there are three main categories:
electrolysis of HCl into chlorine;
oxidation of HCl by nitric acid (Kel-Chlor process);
catalytic oxidation of HCl (Deacon process).
6.1 Electrolysis of HCl solutions
There are three processes:
electrolysis of aqueous solutions using a diaphragm (Uhde process);
gas phase electrolysis (Dupont process);
membrane electrolysis (Bayer/De Nora process).
Electrolysis in an aqueous HCl solution requires an HCl concentration of more than 15% to prevent significant oxygen formation at the anode, and less than 20-22%, above which the conductivity of the electrolyte...
