New progress in research on crystallization technology

The crystallization separation theory and simulation optimization in solution crystallization are outlined.The crystallization processes such as direct cooling crystallization,reaction crystallization,distillation crystallization coupling,redox crystallization liquid membrane,extraction crystallization,magnetization crystallization and so on are summarized.Reasonable designing of crystallizer and crystallization technology is reliable guarantee for industrialization of crystallization processes.The falling film crystallizer,Bremband crystallization technology and the plate type crystallizer are evaluated.It is pointed out that the new crystallization separation unit and technology,technology industrialization,the mechanism of heat and mass transfer of crystallization process need to be further studied.
