Liquid-Liquid Extractor (LLE)
A Liquid-Liquid Extractor uses an immiscible solvent to extract desired components from a liquid feed. Eccentric agitator provides a series of mixing and settling zones for efficient mass transfer.
How It Works:
- Immiscible solvent has higher affinity for desired component
- Continuous and dispersed phases based on properties
- Eccentric agitator creates mixer-settler zones
- Extract: solvent with desired component
- Raffinate: feed with minimal desired component
Features:
✓ Continuous operation vs. batch kettles✓ Reduced solvent consumption, power, and space
✓ Consistent results
✓ High extraction efficiency
Applications:
- Extraction of products or impurities from reaction mass
- Acidity removal by washing
- Separation of close-boiling components
- Wastewater treatment (COD & BOD reduction)
Pilot Plant Available: Test extraction efficiency with your materials
