Impact 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, temperature, and residence time. Modifications to these parameters can significantly affect crystal size, shape, and morphology.
For instance, higher supersaturation levels typically enhance crystal growth rate but may also lead to smaller crystals with reduced quality. Temperature, on the other hand, exerts a dual influence. While elevated temperatures often increase the growth rate, they can also decrease 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.
