CHLOR ALKALI PLANTS

A chlor alkali plant primarily produces three essential chemicals:

• Our electrolysis plants are versatile and can produce a variety of essential chemicals, which are crucial for various industrial applications:

  • Sodium Hypochlorite (14-17%): widely used as a disinfectant and bleaching agent.
  • Caustic Soda (32-50%): A fundamental chemical compound in the manufacture of paper, textiles, detergents and many other industrial products.
  • Hydrochloric Acid (33%): Important in the production of vinyl chloride for plastics, and in metal processing.
  • Hydrogen: A versatile gas that can be used as a fuel, in the production of ammonia and in other chemical processes.

Energy consumption depends on the electrolysis technology used. A membrane cell chlor alkali plant requires 2,500 to 3,000 kWh per metric ton of chlorine produced. Optimizing energy sources, including renewables, can reduce operational costs.

The space requirement depends on plant capacity, technology, and infrastructure needs. A modular chlor alkali plant can be designed to fit within a compact footprint, typically ranging from 500 to 5,000 square meters, allowing for flexibility in industrial settings.

A modular chlor alkali plant can be installed and commissioned within 6 to 12 months, depending on site conditions, permitting, and equipment availability. Pre-assembled modular units significantly reduce setup time.

To ensure safety, chlor alkali plants implement:

• Automated leak detection and emergency shutdown systems.
• Personal protective equipment (PPE) for workers handling chlorine and caustic soda.
• Proper ventilation and scrubbing systems to manage gas emissions.

Yes. Modular chlor alkali plants allow for scalable expansion by adding additional electrolysis cells and support systems. Welysis provides customized capacity upgrades based on market demand.

Key strategies include:

• Using energy-efficient membrane technology to lower electricity costs.
• Implementing process automation to reduce labor and downtime.
• Utilizing byproducts (hydrogen) for additional revenue streams.

Chlor alkali plants must comply with local and international environmental regulations, including:

• Air emission permits for chlorine and hydrogen.
• Water discharge permits for brine treatment.
• Hazardous chemical storage and handling approvals.

Membrane cell technology is the preferred method for modern chlor alkali plants because it:

• Eliminates mercury and asbestos, making it environmentally safer.
• Reduces energy consumption, improving efficiency.
• Produces high-purity sodium hydroxide.

Welysis provides comprehensive support, including:

• 24/7 technical assistance and troubleshooting.
• Spare parts supply and equipment upgrades.
• Ongoing process optimization consulting.

Local chlor alkali plants reduce supply chain risks, transportation costs, and import dependencies, ensuring a stable and cost-effective chemical supply.

Quality is maintained through:

• Regular brine purification to remove impurities.
• Strict monitoring of electrolysis conditions.
• Adhering to international chemical quality standards

To increase profitability, consider:

• Optimizing energy efficiency through advanced membrane cells.
• Diversifying product applications to expand market reach.
• Reducing waste and maximizing byproduct utilization.
