Abstract: It has been a hot topic in the study of chemical separation process to strengthen the chemical separation technology and to realize the energy conservation and emission reduction in the separation process. The study of separation processes enhanced by microwave field is very active in recent years. In this paper,the mechanism of microwave on matters were explained,and the advantages and characteristics of microwave heating compared with conventional heating were discussed. The strengthening effects and application progress of microwave field in extraction,drying,desorption/adsorption,distillation and reactive distillation separation process were introduced systematically,and the strengthening mechanisms of microwave field in these separation processes were summarized and analyzed. The analysis showed that the application of microwave in chemical separation process had the characteristics of high heating speed,high product quality,low energy consumption and easy-control production process. Moreover,the lack of research of microwave in the field of distillation/evaporation and reactive distillation was pointed out. In addition,this paper suggested that a lot of experiments and the corresponding theoretical support were needed to verify whether the microwave was beneficial to the distillation process or reactive distillation process.Meanwhile,the development of microwave in the field of separation was analyzed and forecasted.
