Firstly, this paper discusses the purpose of the recovery section, development in the world, the market prospects and production methods. To find the information of the production installations in the extractive distillation column with water as solvent process, the main purpose is the separation of acrylonitrile and acetonitrile. This article focuses on the acrylonitrile recovery section including process principles and processes discussing. Process parameters of material balance, heat balance and computing equipment, and equipment selection are based on the calculated data. Process controling, "three wastes" are described. Finally, according to the process conditions the use of Auto CAD drawing with a process flow diagram of the control points, completed the design specification of 20 000 words.Key words: Acrylonitrile; Acetonitrile; Solvent water; Recover齐齐哈尔大学毕业设计（论文）III目 录摘 要 ...........................................................................................................................................IAbstract........................................................................................................................................I第 1 章 总 论.............................................................................................................................11.1 概述................................................................................................................................11.1.1 生产的意义与作用..................................................................................................11.1.2 国内外发展现状和发展前景..................................................................................11.1.3 主要产品的性质特点与生产方法..........................................................................11.2 设计依据........................................................................................................................11.3 厂址选择........................................................................................................................11.4 设计规模及生产制度....................................................................................................11.4.1 设计规模..................................................................................................................11.4.2 生产规模..................................................................................................................11.5 原料与产品规格............................................................................................................1第 2 章 工艺设计与计算...........................................................................................................12.1 工艺原理........................................................................................................................12.2 工艺路线的....................................................................................................................12.3 工艺流程简述................................................................................................................12.4 工艺参数........................................................................................................................12.5 物料衡算........................................................................................................................12.5.1 回收塔物料衡算......................................................................................................12.5.2 乙腈塔进行物料衡算..............................................................................................12.5.3 回收塔分成器物料衡算..........................................................................................12.6 热量衡算........................................................................................................................12.6.1 回收塔的热量计算..................................................................................................12.6.2 乙腈塔的热量计算..................................................................................................12.6.3 回收塔分层器的热量计算......................................................................................12.7 Aspen 过程模拟 .............................................................................................................1齐齐哈尔大学毕业设计（论文）IV2.7.1 全流程 Aspen 模拟 ................................................................................................12.7.2 回收塔 Aspen 模拟 ...............................................................................................。
