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  目 录  TOC \o 1-3 \h \z \u  HYPERLINK \l _Toc327126816 摘 要  PAGEREF _Toc327126816 \h I Abstract HYPERLINK \l _Toc327126817   PAGEREF _Toc327126817 \h I  HYPERLINK \l _Toc327126818 第1章 总 论  PAGEREF _Toc327126818 \h 1  HYPERLINK \l _Toc327126819 1.1 概述  PAGEREF _Toc327126819 \h 1  HYPERLINK \l _Toc327126820 1.1.1生产的意义与作用  PAGEREF _Toc327126820 \h 1  HYPERLINK \l _Toc327126821 1.1.2国内外发展现状和发展前景  PAGEREF _Toc327126821 \h 1  HYPERLINK \l _Toc327126822 1.1.3主要产品的性质特点与生产方法  PAGEREF _Toc
