Chloralkali Electrolysis

Chloralkali Electrolysis

A chloralkali process always implies the electrolysis of common salt or sodium chloride. Depending on the method several products beside hydrogen can be produced. If the products are separated, chlorine and sodium hydroxide are the products; by mixing, sodium hypochlorite or sodium chlorate are produced, depending on the temperature.


Richter products are successfully used for conveying different media, e.g.

  • NaCl (raw, purified and ultra-pure brine)
  • Anolyte, NaCl depleted brine
  • Cl2, (wet chlorine gas) 
  • Catholyte, NaOH (caustic 32 - 60%)
  • NaOCl, sodium hypochlorite to 15%
  • H2SO4, sulphuric acid to 98 %, with and without Cl2
  • HCl, hydrochloric acid 


Customer benefits

► Universal corrosion resistance of PFA/PTFE versus metallic materials and standard plastics

► Cost and delivery time advantage of PFA/PTFE lined products versus pumps and valves made of secial metalls

► Nearly universal compatibility enables standardising to less pumps and valves series
