Abstract: Crystallization is a widely used product refining unit operation. Understanding the characteristics of crystallization process in petrochemical industry is helpful for selecting and designing new crystallization process. This review briefly introduces the characteristics of crystallization process, summarizes the crystallization processes applied in petrochemical industry, and discusses some points for crystallization process design. Crystallization in petrochemical process is mainly used in the purification of polymer monomer, and it is often one operation in the whole refining process. Designing a reasonable crystallization process requires consideration of the safety, feasibility, and economy of the process from an overall perspective.
