Effect of Operating Parameters on Crystal Growth in Continuous Crystallizers
Crystal growth within continuous crystallizers is a intricate process influenced by numerous operating parameters. Essential among these are the concentration, heat transfer rate, and here dwell time. Variations to these parameters can profoundly affect crystal size, shape, and purity.
For instance, higher supersaturation levels typically enhance crystal growth rate but may also lead to smaller crystals with reduced quality. Temperature, on the other hand, exerts a complex influence. While elevated temperatures often augment the growth rate, they can also decrease 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 correlation between these operating parameters is crucial for optimizing continuous crystallization processes and achieving desired crystal properties.
