The Influence of Operating Parameters on Crystal Growth in Continuous Crystallizers
Crystal growth within continuous crystallizers is a intricate process influenced by numerous operating parameters. Critical among these are the degree of supersaturation, heat transfer rate, and crystallization time. Variations to these parameters can profoundly affect crystal size, shape, and morphology.
For instance, higher supersaturation levels typically accelerate crystal growth rate but may also lead to smaller crystals with reduced purity. Temperature, on the other hand, exerts a faceted influence. While elevated temperatures often augment the growth rate, they can also diminish crystal size and affect morphology.
Residence time plays a crucial role in determining the equilibrium crystal size by influencing the amount of time crystals have to mature.
