The improvement of environmental awareness poses new challenges to traditional separation methods.This paper introduces the advantages and bottlenecks of extractive distillation as an efficient separation method,focuses on the advantages of mixed solvents as extractants,and discusses the dynamic control scheme and characteristics of extractive distillation system under its influence.With the aid of computers,extractants are designed and screened from a microscopic point of view.At the same time,the economy and benefit of various optimized extractive distillation processes are analyzed.The future development prospect of mixed solvent in extractive distillation process is prospected,and the advantages of low eutectic solvent as a component of mixed solvent are put forward.
