Research progress on micro-chemical rectification and separation technology
The research progress of micro-chemical rectification and separation technology with micro-scale structure as the core is reviewed.Distillation is the most widely used separation method in chemical industry.However,conventional rectification has major drawbacks such as outdated energy saving technology,low equipment efficiency,and low separation performance of near-boiling systems.This review introduces micro-rectification technology,as a novel process intensification means,including external forces of capillary force,centrifugal force,vacuum,gravity,and so on,which plays an important role in flow chemistry applications.Under micro-scale conditions,the efficiency of mass transfer and heat transfer between phases is significantly enhanced with the shortening of the mass transfer distance.Micro-chemical rectification and separation technology is safe and controllable,providing solutions to achieve environmental protection,reduce energy consumption,and improve the development of flow chemistry platforms for chemical synthesis.
