Effect of Operating Parameters on Crystal Growth in Continuous Crystallizers
Crystal growth within continuous crystallizers is a intricate process influenced by numerous operating parameters. Critical among these are the concentration, heat transfer rate, and crystallization time. Variations to these parameters can drastically 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 purity. 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 final crystal size by influencing the amount of time crystals have to develop.
