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, heat transfer rate, and dwell time. Variations to these parameters can profoundly 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 complex influence. While elevated temperatures often augment the growth rate, they can also diminish crystal size and alter 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 fundamental for optimizing continuous crystallization processes and achieving specific crystal properties.
