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 concentration, heat transfer rate, and residence time. Variations 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 lower quality. Temperature, on the other hand, exerts a complex influence. While elevated temperatures often stimulate the growth rate, they can also reduce crystal size and alter morphology.
