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