Caustic soda (Sodium Hydroxide – NaOH) is one of the most basic and widely used chemicals in industries, with global production reaching tens of millions of tons per year. With increasing demand, the application of effective, energy-saving and environmentally friendly caustic soda preparation methods is an important requirement for companies and businesses. Below are the popular and advanced methods in the preparation of caustic soda, along with the benefits and latest technological trends today.
Common methods of preparing caustic soda
This is the main method for producing caustic soda, in which a NaCl solution is electrolyzed to form caustic soda NaOH, chlorine (Cl₂) and hydrogen (H₂). This method is carried out using three main technologies:
Mercury electrode
- Working principle: Using mercury as an electrode, NaCl salt is electrolyzed to produce caustic soda and chlorine.
- Advantage: High efficiency, high purity caustic soda products.
- Disadvantages: Causes serious environmental pollution due to mercury, high operating costs.
- Trend: This technology is being phased out in many countries due to strict environmental regulations.
Diaphragm electrolysis
- Working principle: Use a separator to separate caustic soda and chlorine, minimizing impurities in the product.
- Advantage: Simple, lower operating costs than mercury electrodes.
- Disadvantages: Caustic soda products have medium purity, difficult to control some impurities.
Ion exchange membrane electrolysis
- Working principle: The salt solution is passed through an ion exchange membrane, producing caustic soda and chlorine with high efficiency.
- Advantage:
- Lowest fuel consumption.
- High purity of caustic soda.
- No environmental pollution.
- Trend: This is a technology commonly used in new factories, especially in Europe and developed countries.

Current trends in caustic soda preparation technology
Branch industrial production of NaOH are witnessing major changes to meet the increasing demands for efficiency, cost and environmental protection. Below are the prominent trends in current caustic soda production technology.
1. Eliminate Mercury Cell Technology
Negative impacts of mercury electrode technology
- Environmental impact: Mercury Cell Process technology uses mercury to produce caustic soda, leading to the risk of mercury leakage into the environment, polluting soil, water and air.
- Health effects: Mercury is a potent neurotoxin that causes serious health effects, including damage to the nervous system and internal organs.
Elimination trends in Europe and globally
- Strict legal regulations: In Europe, countries have committed to completely phasing out mercury electrode technology by 2025, in line with international agreements such as the Minamata Convention on Mercury.
- Replace with modern technology: Most new plants today use Ion-Exchange Membrane Technology, completely eliminating dependence on mercury.
2. Prioritize environmentally friendly technology
Ion-Exchange Membrane Technology
- Working principle:
- Table salt (NaCl) solution is passed through an ion exchange membrane, separating the Na⁺ and Cl⁻ ions.
- The Na⁺ ion combines with water to form NaOH, while the Cl⁻ ion is converted to chlorine gas.
- Advantage:
- High performance: Produces high purity NaOH.
- No pollution: No mercury or asbestos used, ensuring no toxic waste is generated.
- Emission reduction: Reduce CO₂ and other harmful gas emissions.
Sustainability
- Ion exchange membrane technology meets the trend of sustainable development, helping businesses reduce environmental impact and comply with international standards such as ISO 14001.
3. Save energy and reduce production costs
Optimize energy consumption
- Modern technology:
- Using advanced ion exchange membranes significantly reduces power consumption compared to older technology (Mercury Cell or Diaphragm Cell).
- Integrate Smart Energy Management Systems to reduce waste.
- Benefits:
- Reduce operating costs, thereby lowering product prices.
- Increase business competitiveness in the global market.
Automation
- IoT and AI Applications: Today's manufacturing plants use automated control systems based on IoT (Internet of Things) and AI (Artificial Intelligence) to optimize production processes, thereby:
- Improve production efficiency.
- Minimize errors and waste of materials.
- Real-time product quality monitoring.
4. Benefits for businesses when applying new technology
- Enhance reputation and brand: Compliance with international standards on environmental protection and sustainability helps businesses improve their image in the market.
- Increase profits: Reduce production costs through energy savings and process optimization.
- Market expansion: Products are of high quality, meeting the strict requirements of the international market, especially in the food, pharmaceutical and chemical industries.
Benefits of adopting modern technology
- Increase production efficiency:
- High efficiency, minimizing waste of raw materials and energy.
- Meet environmental standards:
- Comply with strict regulations on environmental protection, enhance business reputation.
- Reduce operating costs:
- Low energy consumption technology significantly reduces production costs and increases profits.
- High quality products:
- NaOH has high purity, meeting the requirements of industries such as food, pharmaceutical and chemical.
