Product details
Asia Chemical Engineering Co., Ltd. is a leading Chinese manufacturer and supplier of high-efficiency caustic soda electrolysis plants. We deliver cost-effective, fully customizable membrane cell electrolysis solutions with reliable quality, competitive pricing, and comprehensive after-sales support.
Key Advantages of Our Caustic Soda Electrolysis Plant
✅ Ultra-Low Energy Consumption for Lower Operating Costs
Our electrolyzer uses high-efficiency electrode structures and imported ion-exchange membranes (Asahi Kasei, DuPont), reducing power consumption to just 2100–2300 kWh per ton of 30% caustic soda. This is 30% lower than traditional diaphragm electrolysis and 15% lower than mercury electrolysis. For a 50,000-ton/year plant, this translates to annual savings of 4.5–7.5 million kWh of electricity, significantly cutting your production costs.
✅ High-Purity Output to Meet Premium Market Standards
The ion-exchange membrane precisely separates anode and cathode chambers, producing caustic soda with purity ≥99.5%, free of mercury, asbestos, and other impurities. Our plants support production that meets strict standards including:
- Food-grade (GB 5175)
- Pharmaceutical-grade (USP/EP)
- Electronic-grade (SEMI C7)
- This enables you to access high-margin markets with confidence.
✅ Zero Environmental Pollution & Full Regulatory Compliance
No mercury-containing catalysts or asbestos diaphragms are used, eliminating heavy metal pollution and sludge discharge. Wastewater meets EU REACH, US EPA, and China GB 21521 standards. Byproducts (high-purity Cl₂ and H₂) are fully recyclable, helping you meet EU CBAM carbon footprint requirements and environmental regulations worldwide.
✅ Stable, Continuous Operation with Minimal Downtime
Thanks to the membrane’s excellent chemical stability and the electrolyzer’s modular design, our plants operate continuously for 8000+ hours per year with a failure rate of less than 0.5%. This avoids costly production interruptions caused by equipment malfunctions, ensuring consistent output for your business.

FAQ
What factors affect the service life of ion-exchange membranes in the electrolysis plant? How to reduce replacement costs?
The main factors are brine purity and electrolysis operating parameters, and we provide a full-set maintenance plan to reduce costs:
① Brine purification: The plant is equipped with a chemical precipitation + ultrafiltration system, removing 99% of Ca²⁺, Mg²⁺, and other impurities that cause membrane scaling, extending service life by 1–2 years.
② Parameter control: The PLC system automatically maintains current density at 2–4 kA/m² (optimal range) to avoid membrane degradation from overcurrent.
③ Regular maintenance: We provide special cleaning agents and procedures; semi-annual cleaning can restore 90% of membrane performance. The membrane replacement cost accounts for only 5–8% of annual operating costs, and modular design allows replacement without stopping the entire production line (2–3 hours per electrolyzer).
