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 degree of supersaturation, temperature, and crystallization time. Modifications to these parameters can drastically affect crystal size, shape, and morphology.
For instance, higher supersaturation levels typically promote crystal growth rate but may also lead to smaller crystals with poorer quality. Temperature, on the other hand, exerts a faceted influence. While elevated temperatures often stimulate the growth rate, they can also diminish 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 develop.
Understanding the interplay between these operating parameters is crucial for optimizing continuous crystallization processes and achieving desired crystal properties.
