Effect of Operating Parameters on Crystal Growth in Continuous Crystallizers
Crystal growth within continuous crystallizers is a intricate process influenced by numerous operating parameters. Key among these are the degree of supersaturation, heat transfer rate, and dwell time. Adjustments to these parameters can profoundly affect crystal size, shape, and purity.
For instance, higher supersaturation levels typically enhance crystal growth rate but may also lead to smaller crystals with lower purity. Temperature, on the other hand, exerts a complex influence. While elevated temperatures often increase the growth rate, they can also reduce crystal size and affect morphology.
Residence time plays a crucial role in determining the final crystal size by influencing the amount of time crystals have to mature.
