Crystallization Calculator
Design batch and continuous crystallizers with yield and purity calculations
Input Parameters
Concentration at starting temperature
Must be less than initial concentration
Accounts for losses and incomplete crystallization
Typical range: 10⁻⁹ to 10⁻⁷ m/s
Quick Reference
- • Cooling: Lower temperature reduces solubility
- • Evaporative: Remove solvent to increase concentration
- • Higher supersaturation = faster crystallization
- • Slower cooling = larger, purer crystals

Design Recommendations
- ⚠ High supersaturation - may cause rapid nucleation and small crystals
- ⚠ Low yield - consider lower final temperature
- • Consider seeding to control crystal size distribution

The difference between initial concentration and final solubility determines the maximum theoretical yield. Operating within the metastable zone (MSZW) prevents excessive nucleation.
