The Influence of Operating Parameters on Crystal Growth in Continuous Crystallizers
Crystal growth within here continuous crystallizers is a intricate process influenced by numerous operating parameters. Essential among these are the concentration, temperature, and crystallization time. Modifications to these parameters can drastically affect crystal size, shape, and crystalline quality.
For instance, higher supersaturation levels typically accelerate crystal growth rate but may also lead to smaller crystals with poorer purity. Temperature, on the other hand, exerts a faceted influence. While elevated temperatures often augment the growth rate, they can also reduce crystal size and alter morphology.
Residence time plays a crucial role in determining the ultimate crystal size by influencing the amount of time crystals have to mature.
