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 supersaturation, temperature, and residence time. Adjustments to these parameters can significantly affect crystal size, shape, and purity.
For instance, higher supersaturation levels typically promote crystal growth rate but may also lead to smaller crystals with reduced purity. Temperature, on the other hand, exerts a faceted influence. While elevated temperatures often stimulate the growth rate, they can also diminish crystal size and alter morphology.
Residence time plays a crucial role in determining the final crystal size by influencing the amount of time crystals have to mature.
Understanding the relationship between these operating parameters is essential for optimizing continuous crystallization processes and achieving target crystal properties.
