Recent progress in melt crystallization

With the increasingly fierce competition in the chemical industry and the increasing attentions paid to environmental protection by human beings around the world, the development of green and efficient industrial purification technology has become an inevitable trend, and the crystallization purification method has attracted the attentions of industry due to its good purification effect. Melt crystallization is widely used in industrial production due to its advantages of green, high efficiency and low energy consumption. This paper introduces the classification and principle of melt crystallization, and compares it with rectification and solution crystallization. Next, the influencing factors of the crystallization process are systematically summarized from three aspects: crystallization, sweating and external factors. Then, the coupling methods of melt crystallization with other techniques are reviewed. Finally, the prospect of melt crystallization is discussed.
