Fully Automatic Caustic Soda Flake Plant Featuring Skid Mounted Plug-Play and Salt Purity Requirement Only NACL>89%
Product Spotlights
As a leading manufacturer based in Tianjin, China, Tianjin ZhuoLiNeng (ZLN) Technology Co., Ltd. is proud to introduce our Fully Automatic Caustic Soda Flake Plant featuring a skid-mounted plug-and-play design. This innovative solution is engineered to transform low-grade salt (NaCl > 89%) into high-purity caustic soda flakes with minimal installation complexity and operational cost. By integrating advanced automation, our plant delivers consistent product quality, energy efficiency, and rapid deployment—ideal for clients seeking a reliable, turnkey production system.
The plant’s core advantage lies in its ability to utilize salt with purity as low as 89% NaCl, significantly reducing raw material expenses while maintaining superior output. With a fully automatic PLC control system, the entire process from brine purification to evaporation, concentration, and flaking is seamlessly managed, ensuring stable operation and minimal human intervention. Whether you are expanding existing capacity or building a new facility, our skid-mounted design allows for quick installation on a prepared foundation, cutting project timelines by up to 50% compared to traditional plants.
Key Features & Technical Specifications
Plug-and-Play Skid Mounting: Pre-assembled modules on heavy-duty skids reduce on-site construction to a minimum. All piping, wiring, and instrumentation are factory-tested, allowing for commissioning within 2–3 weeks.
Low Salt Purity Tolerance: Accepts industrial salt with NaCl content > 89%, eliminating the need for expensive high-purity salt. This feature directly lowers raw material costs by 15–30%.
Fully Automatic PLC Control: Siemens or Mitsubishi PLC with HMI touchscreen provides real-time monitoring of temperature, pressure, flow rate, and concentration. Automatic alarm and shutdown protection ensure safety.
Energy-Efficient Evaporation: Multi-effect evaporation system (MEE) with forced circulation reduces steam consumption by up to 40% compared to single-effect designs. Optional mechanical vapor recompression (MVR) further enhances efficiency.
High Purity Output: Produces caustic soda flakes with NaOH content ≥ 99% (or as per customer requirement), meeting international standards for industrial use.
Compact Footprint: Skid-mounted modules occupy 30% less floor space than traditional plants, making it suitable for sites with limited area.
Flexible Capacity: Available in standard capacities from 10,000 to 50,000 MT/year, with custom designs available upon request.
Corrosion-Resistant Materials: Main equipment constructed from 316L stainless steel or nickel alloys for long service life in aggressive alkali environments.
Technical Parameters (Typical 20,000 MT/year Plant)
| Parameter | Value |
| Annual Capacity | 20,000 MT (customizable) |
| Raw Material Salt Purity | NaCl ≥ 89% |
| NaOH Flake Purity | ≥ 99% (adjustable) |
| Steam Consumption | ~1.2 tons per ton of NaOH (MEE) |
| Power Consumption | ~80 kWh per ton of NaOH |
| Operating Temperature | Max 160°C (evaporation stage) |
| Control System | PLC + HMI (Siemens/Mitsubishi) |
| Skid Dimensions | 12m x 3m x 4m (per module) |
The plant is designed with modular skids that can be easily transported in standard containers, simplifying logistics for international projects. Each skid includes all necessary electrical cabinets, interconnecting pipes, and valves, so only utility connections (steam, water, electricity) are required on site. This plug-and-play approach drastically reduces the risk of installation errors and speeds up time-to-production.

Frequently Asked Questions (FAQ)
Q: What is the minimum salt purity required for this plant?
A: The plant is designed to work with salt containing NaCl > 89% by weight. If your salt has lower purity, we can customize the brine purification section to handle higher impurities.Q: How long does it take to install and commission the skid-mounted plant?
A: Thanks to the plug-and-play design, typical installation and commissioning can be completed within 3–4 weeks after arrival on site, depending on local utility readiness.Q: Can the plant produce different grades of caustic soda?
A: Yes, the fully automatic control system allows you to adjust production parameters to obtain flakes with NaOH content from 97% to 99.5% as per your requirements.Q: What is the typical power and steam consumption per ton of product?
A: Approximate consumption is 1.2 tons of steam and 80 kWh of electricity per ton of NaOH flakes. These values can be optimized with the optional MVR system.Q: Do you provide training for operators?
A: Yes, we offer comprehensive on-site training for your operators and maintenance staff, including both theoretical and practical sessions. We also provide detailed operation manuals.Q: What materials are used for the evaporator and flaker?
A: The evaporator bodies are made of 316L stainless steel, while the flaker drum is made of nickel-based alloy to resist corrosion. Other parts can be customized based on your specific requirements.Q: Is the plant certified for international standards?
A: Our equipment is designed and manufactured in accordance with ASME, GB, and CE standards (optional). We can provide necessary documentation for your local certification process.Q: Can you supply spare parts for long-term operation?
A: Absolutely. We maintain a comprehensive inventory of spare parts in our Tianjin warehouse and can ship them worldwide within 2–3 days for urgent needs.
