NaCl / Chlorine alkali
NaCl and chlor-alkali processes: concentration, crystallization, and recovery
FE supports manufacturers in the chemical and agri-food industries in the treatment and recovery of sodium chloride (NaCl) salt solutions, particularly in chlor-alkali processes.
Brine concentration: for electrolysis or the food industry
Our evaporators concentrate depleted brine in order to:
- Reinjecting concentrated brine into electrolysis processes (production of chlorine, soda, hydrogen)
- Providing high-quality brine for food industry applications
Salt crystallization: purification and quality
Crystallization produces purified salt that meets process requirements:
- Chemical (electrolysis, synthesis)
- Food industry (table salt, additives)
A purification step can be integrated depending on the quality of the incoming brine, ensuring that the final product complies with specifications.
Corrosion-resistant materials
The equipment is designed with materials suitable for saline and corrosive environments, ensuring:
- Sustainability
- Facility security
- Compliance with industry standards
Soda concentration: supplement to the chlor-alkali process
FE also offers units for soda concentration, with or without MVR, enabling 50% soda to be obtained:
- Reduction in energy consumption
- Reduction in CO₂ emissions
- Electrification of the process for improved environmental performance
MVR technologies: energy efficiency
Mechanical Vapor Recompression (MVR) is integrated into our solutions for:
- Reduce operating costs
- Optimize thermal performance
- Addressing the challenges of industrial decarbonization
