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 supersaturation, temperature, and crystallization time. Modifications to these parameters can significantly affect crystal size, shape, and crystalline quality.
For instance, higher supersaturation levels typically accelerate 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 increase the growth rate, they can also reduce 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.
Understanding the interplay between these operating parameters is crucial for optimizing continuous crystallization processes and achieving desired crystal properties.
