Bases
Bases: sodium hydroxide and potash concentration for efficient recovery
FE offers thermal solutions for the concentration of strong bases, mainly:
- Caustic soda (NaOH)
- Caustic potash (KOH)
These products are used in many industrial sectors: chemicals, pharmaceuticals, food processing, surface treatment, etc.
Objective: refocusing and enhancement
Concentration allows you to:
- To recycle diluted solutions
- To produce concentrated bases (up to 50% for soda)
- To reduce the volumes to be transported or stored
Technologies tailored to specific products
Depending on the target concentration and temperature, FE offers:
- Vacuum or atmospheric evaporation systems
- Specific technologies for concentrated bases
- Suitable materials (special alloys, anti-corrosion coatings) to ensure safety and durability
Mechanical vapor compression (MVR): reducing consumption
Our units can integrate MVR, enabling:
- A significant reduction in gas consumption
- Electrification of the process
- A reduction in CO₂ emissions
- Improved energy efficiency, even at high concentrations
Typical applications:
- Recycling of diluted soda or potash
- Production of 50% soda ash for chemical processes
- Valorization of alkaline co-products
