Evaporation Solutions in Production Process

1. Feed Brine Refining

Utilize MVR Evaporation Solution to produce high-purity NaCl. This ensures the feedstock meets the strict requirements for membrane electrolysis, preventing membrane fouling and extending the lifespan of your electrolyzers.
2. Lye Concentration (32% to 50% NaOH)
Efficiently concentrate dilute caustic soda from 32% to 50% concentration by MEE Evaporation Solutions.
3. Salt & Sulfate Recovery (Zero Liquid Discharge)
Recovery the Na2SO4 salt and concentrated NaCl solution after the Membrane Sulfate removal section by Salt recovery evaporation system.

Why Choose Sanfeng Tech for Your Project?

With over 60 years of industry heritage and 100+ successful project cases, we are a trusted partner for your evaporation needs.

  • Process Optimization: We don’t offer one-size-fits-all solutions. Our engineers customize MEE (3~6 effects) or MVR setups based on your specific steam-to-electricity cost ratio to minimize your operating expenses.
  • Corrosion-Resistant Engineering: Expertise in material selection (Titanium, Duplex Steel, Ni-Alloy) optimized for aggressive chlor-alkali media, ensuring long equipment life.
  • Large-Scale Capacity: Proven track record with systems capable of handling large volumes, including 150t/h large-scale plants.
  • International Compliance: Familiar with international certification, ensuring your project meets local regulatory requirements.
