Q: What are the advantages of your ion-exchange membrane caustic soda production line?
A: Our line features lower power consumption (0.556T coal saved per ton vs. the precipitation method), higher product purity (salt content below 40ppm), zero asbestos/mercury pollution, lower production cost, and simpler operation.

Q: Can your caustic soda production line be expanded to produce other related products?
A: Yes. Our system is highly flexible and can be integrated with follow-up units for caustic soda condensation, hydrochloric acid, liquid chlorine, sodium hypochlorite, and PVC production, according to your needs.

Q: What is the salt and HCl content of the caustic soda produced by your equipment?
A: Our ion-exchange membrane process ensures extremely low salt and HCl content in the final product, making it ideal for producing solid caustic soda and facilitating long-term storage and transportation.

Q: Do you provide a complete turnkey solution for caustic soda plants?
A: Yes. We offer full turnkey services including brine treatment, electrolysis, dechlorination, gas processing, installation, commissioning, and technical support for the entire caustic soda production line.

Q: What makes your caustic soda production line competitive in the market?
A: Our equipment delivers high-purity products with low impurities, easy handling of solid caustic soda, convenient transportation/storage, and strong adaptability, making it highly competitive in both domestic and international markets.

Q: What is the total investment range for a 50,000 tons/year ion-exchange membrane caustic soda plant?
A: The full turnkey investment for a 50,000 t/a ion membrane caustic soda production line ranges from USD 2.2M–3.5M, covering electrolysis equipment, brine purification system, chlorine & hydrogen treatment unit, PLC automatic control, factory layout design, overseas installation and commissioning. Final cost depends on your factory building conditions, auxiliary equipment and extended downstream units (solid caustic soda, hydrochloric acid etc.). We will send you a detailed cost breakdown after confirming your demand.

Q: Can your caustic soda production line meet environmental protection standards in Africa and the Middle East?
A: Absolutely. Our flue gas desulfurization, dust removal and waste liquid treatment systems are fully customizable to match local emission standards across Africa, Middle East and Southeast Asia. We provide complete environmental test reports and certification documents to help you finish local environmental impact assessment (EIA) smoothly without extra costs.

Q: How long does overseas installation and commissioning take?
A: After all equipment arrives at your site, our professional chlor-alkali engineering team needs 60–90 working days to complete full pipeline assembly, equipment debugging, production test run and operator training for medium & large capacity caustic soda plants. We can flexibly adjust engineers’ schedule according to your factory construction progress.
