Asia Chemical Engineering Co., Ltd. is one of the most reliable manufacturers and suppliers of caustic soda electrolysis plant in China. Please rest assured to wholesale cost-efficient caustic soda electrolysis plant from our factory. Good service and reasonable price are available.
- Ultra-Low Energy Consumption: The electrolyzer adopts a high-efficiency electrode structure and imported ion-exchange membranes (Asahi Kasei, DuPont), with a power consumption of only 2100–2300 kWh/ton of caustic soda-30% lower than diaphragm electrolysis and 15% lower than mercury electrolysis. For a 50,000-ton/year plant, this saves 4.5–7.5 million kWh of electricity annually.
- High-Purity Output: The ion-exchange membrane precisely separates anode and cathode chambers, producing caustic soda with purity ≥99.5% (free of mercury, asbestos, and other impurities). It meets food-grade (GB 5175), pharmaceutical-grade (USP/EP), and electronic-grade (SEMI C7) standards, supporting access to high-margin markets.
- Zero Environmental Pollution: No mercury-containing catalysts or asbestos diaphragms, avoiding heavy metal pollution and sludge discharge. Wastewater meets EU REACH, US EPA, and China GB 21521 standards; byproducts (high-purity Cl₂, H₂) are recyclable, complying with carbon footprint requirements of EU CBAM.
- Stable Operation: The membrane's chemical stability and the electrolyzer's modular design ensure continuous operation for 8000+ hours/year, with a failure rate of less than 0.5%-avoiding production interruptions caused by equipment malfunctions.
Application of Output: Cover High-Demand Industries
The caustic soda produced by the electrolysis plant is widely used in:
- Chemical industry: PVC synthesis, detergent production, organic chemical intermediates.
- Food & Pharmaceutical: Fruit/vegetable peeling, edible oil refining, pharmaceutical purification.
- Electronics: Cleaning of semiconductor components, electronic-grade chemical production.
- Water Treatment: Neutralization of acidic wastewater, drinking water purification.
- Textile & Papermaking: Cotton mercerization, pulp bleaching, paper sizing.
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).
