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