蒸馏过程强化技术研究进展

蒸馏过程强化技术作为我国现代化学工业发展的重要研究领域，是过程强化概念在化学工业成功应用的典范之一。随着近些年的发展，蒸馏过程强化技术的研究已形成了一套较完整的体系，但也出现了一系列新的难题与挑战。为此，本文针对混合物相对挥发度与气液传质两个蒸馏过程强化的基础理论本质问题，以基础理论创新、关键技术突破和关键装备研究进展为主线，从强化原理、研究进展、工业应用及发展3方面系统介绍共沸蒸馏、萃取蒸馏、反应蒸馏这3类典型的引入质量分离剂强化的蒸馏过程及其耦合技术；微波、超重力场等典型外场作用下的引入能量分离剂强化的蒸馏过程，并系统介绍以新型塔内件及新型塔结构为切入点的基于先进设备强化的蒸馏过程，为迎接这一领域新的难题和挑战提供新思路。

State-of-the-arts review of the research process for distillation process intensification technology

As the most important research field of the modern chemical industry development in our country,distillation process intensification technology is a successful example of the application of process reinforcement in the chemical industry field. With the development of recent years,the study of distillation process intensification technology has formed a relatively complete system,but there are also a series of new difficult problems and challenges. Therefore,aiming at two important essential questions of relative volatility intensification and mass transfer process intensification,this paper will focus on the basic theory innovation,the key technology breakthrough and the key equipment research to comprehensively introduce the following three aspects:the introduction of mass separating agent to strengthen distillation process,the introduction of energy separating agent to strengthen distillation process and advanced equipment to strengthen distillation process. Azeotropic distillation,extractive distillation and reactive distillation are the typical strengthen distillation process of mass separating agent. The typical energy separating agents are the plus fields such as microwave field,high gravity field,magnetic field,electric field and ultrasonic field. Those were introduced in detail in the first and second part of this paper. In the last part,new type of packing,new type of tray and divided wall distillation column were systematic introduced.
