In short
The chlor-alkali process is an industrial chemical process that produces chlorine, caustic soda (sodium hydroxide) and hydrogen through electrolysis of brine.
The process consists of brine preparation and purification, electrolysis, product separation, concentration and storage. Membrane cell technology is widely used today.
Electrolysis is energy-intensive, so energy efficiency, cell performance monitoring and maintenance planning are decisive for plant economics. Because of hazardous products such as chlorine, process safety and traceability are also priorities.
