During the chlor-alkali electrolysis, salt (sodium chloride - NaCl) is separated into its components chlorine and sodium.
The sodium part is further processed in various derivatives, for example as soda lye or caustic soda, as well as sodium hypochlorite. Chlorine is used in many applications. Its largest application area is the manufacture of plastics such as polyvinylchloride (PVC), polycarbonate or as intermediate product isocyanate (MDI) in polyurethane synthesis.
For the highest requirements of the various electrolysis technologies, esco offers a great number of rock and vacuum salt qualities.
