Effect 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 supersaturation, temperature, and dwell time. Variations to these parameters can significantly affect crystal size, website shape, and purity.
For instance, higher supersaturation levels typically promote crystal growth rate but may also lead to smaller crystals with lower quality. 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 grow.
Understanding the relationship between these operating parameters is crucial for optimizing continuous crystallization processes and achieving target crystal properties.
