Firstly, It discusses the aim of the extraction section, the domestic and overseas developing condition,the comparison of the extraction solvent and the process, the market prospect and production method.It can be confirmed that the new carom extraction process uses the glycofurol as solvent by checking the relevant material, its main aim is to separate the aromatic hydrocarbon and the non aromatic hydrocarbon in the reforming oil. This article mainly states the extraction process of the aromatic hydrocarbon including the principle and flow of the process. The operation of the material balance calculation, heat balance calculation and equipment calculation is carried out according to the process parameters, and then to select the type of the equipment on the basis of the calculation data. It also states the process control fire emergency, waste dispose for the process. Lastly, the process flow sheet with control point has been drawn using the Auto CAD referring to process conditions, and the 20000 words design specification has also been finished. Key words: Aromatics；Aromatic hydrocarbon extraction；Catalytic reforming；G 目 录 摘　要 Ⅰ Abstract Ⅱ 第1章 总 论 1 1.1 概述 1 1.1.1生产意义及作用 1 1.1.2国内外研究现状及发展前景 1 1.1.3产品性质与特点 3 1.1.4生产方法的概述 3 1.2 设计依据 3 1.3 厂址的选择及对比 4 1.4 设计规模及生产制度 6 1.4.1设计规模 6 1.4.2生产制度 6 1.5 原料与产品技术规格 6 第2章 工艺设计与计算 9 2.1 工艺原理 9 2.2 工艺路线的选择 9 2.3 工艺流程简述 10 2.3.1工艺流程示意图 10 2.3.2工艺流程简述 11 2.4 工艺参数 11 2.5 物料衡算 12 2.5.1物料衡算 12 2.5.2物料衡算表 15 2.6 热量衡算 15 2.6.1热量衡算 15 2.6.2热量衡算表 18 2.7 Aspen过程模拟 18 第3章 设备选择 24 3
