Liquid-Liquid Extraction Calculator
Design countercurrent extraction systems using distribution coefficients
Input Parameters
Higher K = better extraction
Quick Reference
- • K > 1: Solute prefers extract phase
- • K < 1: Solute prefers raffinate phase
- • Higher S/F: More stages, less solvent per stage
- • Extraction factor (A) = K × (S/F)

vs target 5.00%
Design Recommendations
- ✓ Good extraction factor - efficient separation
- ⚠ Low recovery - increase stages or S/F ratio
