Ammonium-based salts: high concentration and crystallization performance
FE designs and implements industrial units for evaporation concentration and crystallization of ammonium-based salts, such as:
- Ammonium sulfate ((NH₄)₂SO₄)
- Ammonium nitrate (NH₄NO₃)
- Ammonium chloride (NH₄Cl)
These salts are produced by chemical processes or effluent treatment, and can be recycled in the fertilizer or chemical industries.
Two complementary approaches
- Evaporation allows saline solutions to be concentrated, thereby reducing the volumes to be treated and facilitating storage or further processing.
- Crystallization produces purified salt in solid form, ready for use or sale.
High energy efficiency technologies
Our facilities incorporate advanced technologies such as Mechanical Vapor Recompression (MVR), which drastically reduce energy consumption, even on large-capacity units.
IFC® crystallizers: performance and quality
Our exclusive IFC® (Indirect Forced Circulation) technology enables:
- Controlled crystal size (adjustable D50)
- A narrow particle size distribution
- A reduction in fines
- Easy drying
- Greater energy efficiency than conventional technologies (DTB, FC)
Typical applications
- Valorization of chemical co-products
- Treatment of ammonium-rich effluents
- Production de fertilisants granulés de haute qualité
