摘　　要：化工分离是化工生产过程中非常重要的一环。传统的精馏技术在分离效率和能源消耗方面存在一定的问题。为了解决这些问题,多效精馏技术应运而生。多效精馏是一种高效节能的分离技术,通过多次蒸汽压缩和回收利用废热,实现能源的最大化利用。综述多效精馏的原理和工艺流程,并分析其节能效果。同时,探讨多效精馏在石油化工、化学工业中的应用,并通过案例分析来验证其实际效果。Chemical separation is a very important part in the process of chemical production.Traditional distillation technology has some problems in separation efficiency and energy consumption.In order to solve these problems,multi-effect distillation technology came into being.Multi-effect distillation is an energy-efficient separation technology that maximizes energy use through multiple steam compression and recovery of waste heat.In this paper,the principle and process flow of multi-effect distillation are reviewed,and its energy-saving effect is analyzed.At the same time,the application of multi-effect distillation in petrochemical and chemical industry is discussed,and its practical effect is verified by case analysis.
