Chlor-alkali production

Energy efficiency, strict emissions regulations and secure waste handling are challenges faced by the chlor-alkali industry. Manufacturers need reliable, energy-efficient and sustainable processes to produce chlorine, hydrogen and caustic soda. To meet these needs, Alfa Laval has a broad range of high-performance heat transfer components and complete engineered solutions that cut costs and raise yields.

Reliable, energy-efficient and sustainable

  • Broad range to fit easily into heat transfer positions along all electrolysis proces
  • Significantly lower installation height
  • Compact design and highly efficient systems
  • Vast chlor-alkali process experienced experts team
  • Low operating temperatures, reduces corrosion rates

Chlorine is co-produced with caustic soda by the electrolysis of sodium chloride in the chlor-alkali process. Chlorine is used for Vinyls/PVC production, organic chemicals production, chlorinated intermediates production, to sterilize water and sewage, to bleach pulp and textiles, in inorganics and , inorganic chemicals production, alumina manufacture, textile treatments, soap and detergent production, neutralization and other applications. Every year 10-20 new plants are built in the world. 

Producing chlorine, hydrogen and caustic soda involves electricity-intensive processes, which account for about half of the total manufacturing costs. Chlor-alkali producers and EPC companies can rely on Alfa Laval’s well-proven components and ability to supply energy-saving heat transfer equipment and caustic evaporation systems.

Our broad range of high-performance gasketed, semi-welded and welded heat exchangers fit easily into heat transfer positions along all electrolysis process lines. For duties such as brine pre- treatment, wet chlorine gas cooling, hydrogen gas cooling and electrolyte heating and cooling, Alfa Laval has vast chlor-alkali process experience in supplying equipment to chlor-alkali producers the world over.
