Chlor-Alkali Membrane Electrolysis Plant
We provide complete engineering solutions for Chlor-Alkali Membrane Electrolysis Plant, covering the major process units from brine preparation to final caustic soda storage. Our solution is suitable for new chlor-alkali projects, plant expansion, capacity upgrades, and modernization of existing facilities.
The core of the production line is the ion-exchange membrane electrolyzer. Through controlled electrolysis of purified sodium chloride brine, the system produces caustic soda together with chlorine and hydrogen as co-products. The membrane process allows these products to be efficiently separated while maintaining high product quality.
A complete project can be configured according to the required production capacity and site conditions. We optimize the process layout, equipment configuration, energy consumption, automation level, and utility requirements during the engineering stage.
