Effect 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 degree of supersaturation, temperature, and crystallization time. Adjustments to these parameters can drastically affect crystal size, shape, and purity.
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 faceted influence. While elevated temperatures often augment the growth rate, they can also reduce crystal size and affect morphology.
