Impact 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, temperature, and crystallization time. Variations to these parameters can drastically affect crystal size, shape, and purity.
For instance, higher supersaturation levels typically accelerate crystal growth rate but may also lead to smaller crystals with lower purity. Temperature, on the other hand, exerts a faceted influence. While elevated temperatures often increase 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 grow.
