Impact 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 supersaturation, heat transfer rate, and dwell time. Adjustments to these parameters can significantly affect crystal size, shape, and morphology.
For instance, higher supersaturation levels typically promote 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 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.
