Impact 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, thermal conditions, and dwell time. Variations to these parameters can drastically affect crystal size, shape, and purity.
For instance, higher supersaturation levels typically accelerate crystal growth rate but may also lead to smaller crystals with reduced quality. Temperature, on the other hand, exerts a dual influence. While elevated temperatures often stimulate the growth rate, they can also diminish crystal size and affect morphology.
Residence time plays a crucial role in determining the ultimate crystal size by influencing the amount of time crystals have to mature.
Understanding the relationship between these operating parameters is crucial for optimizing continuous crystallization processes and achieving target crystal properties.
