Titanium Anodes for Chlor-Alkali Electrolysis Systems
Engineered for chlorine evolution, brine electrolysis, caustic soda production, and membrane cell operation. Hele Titanium provides Ru-Ir MMO coated titanium anodes, titanium mesh anodes, replacement anode assemblies, and project-specific coating solutions for chlor-alkali electrolysis systems.
Industrial Chemical Production
Chlor-alkali electrolysis converts purified brine into chlorine, caustic soda, and hydrogen through controlled electrochemical reactions. In membrane cell systems, anode coating stability, titanium substrate quality, current distribution, and dimensional accuracy directly affect chlorine evolution efficiency and service life.
Hele Titanium supports chlor-alkali projects with Ru-Ir MMO coated titanium anodes, titanium mesh substrates, replacement anode assemblies, and project-ready technical documentation for OEMs, system integrators, and chemical producers.
How Chlor-Alkali Electrolysis Works
Chlor-alkali electrolysis separates purified brine into chlorine, caustic soda, and hydrogen through a membrane cell. Ru-Ir MMO coated titanium anodes drive chlorine evolution in the anode chamber, while the membrane helps separate products and control ion transport.
Purified Brine Enters the Anode Chamber
Sodium chloride brine is purified and fed into the anode side of the membrane cell.
Ru-Ir MMO Titanium Anodes Drive Chlorine Evolution
Coated titanium anodes convert chloride ions into chlorine gas under controlled DC current.
Sodium Ions Pass Through the Membrane
The ion-exchange membrane separates the anode and cathode chambers while allowing sodium ion transport.
Caustic Soda and Hydrogen Form at the Cathode
Water reduction produces hydrogen and hydroxide ions, forming sodium hydroxide in the cathode chamber.
Products Are Collected Separately
Chlorine, caustic soda, and hydrogen are collected through separate outlets for downstream use.
Typical Chlor-Alkali Membrane Cell System
Engineered with premium titanium materials and advanced electrochemical anodes, our integrated membrane cell solutions deliver exceptional durability and optimized energy efficiency for demanding industrial applications.
