There are many benefits to using continuous cooling crystallization. Below, we highlight some of these:
- Low-temperature operation – low corrosion rates, less product degradation, no tar formation
- Enclosed systems with little or no leakage
- Favorable equilibrium – wide spread of organic chemical freezing points
- High purity – crystals formed usually are 100% pure
- Continuous process using Armstrong/Chemtec equipment
