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. Key among these are the concentration, temperature, and dwell time. Variations to these parameters can significantly 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 dual influence. While elevated temperatures often increase the growth rate, they can also diminish crystal size and alter morphology.
Residence time plays a crucial role in determining the equilibrium crystal size by influencing the amount of time crystals have to develop.
Understanding the relationship between these operating parameters is fundamental for optimizing continuous crystallization processes and achieving specific crystal properties.
