2500乙酸乙酯..doc

东北石油大学本科生毕业设计（论文） PAGE 摘 要 乙酸乙酯（EA）是一种重要的化工溶剂，在涂料、粘合剂、制药和油墨等领域的应用十分广泛，其合成过程也受到广泛重视。其制备方法有酯化法、乙醛缩合法、乙醇脱氢法和醋酸/乙烯加成法。其中传统制备方法为酯化法，即乙酸和乙醇在浓硫酸的催化下生成乙酸乙酯。由于国内主要以酯化法为主，酯化法生产乙酸乙酯的工艺方法比较成熟，故本次设计采用酯化法。确定了2500t/a乙酸乙酯的车间工艺流程，通过利用物料守恒，能量守恒等基本的原理，运用逐板计算等基本方法设计了分离塔、换热器等设备，并确定型号。 关键词：乙酸乙酯；酯化法；物料衡算；热量衡算；车间工艺设计 Abstract Ethyl acetate (EA) is an important chemical solvents, is widely used in coatings, adhesives, pharmaceutical, inks and other areas, the synthesis process is also widespread attention. The preparation method has esterification, acetaldehyde condensation, dehydrogenation of ethanol and vinyl /acetate addition process.Convent- ional methods is esterification, Under the calalytic of the concentrated sulfuric acid and ethanol are generated into ethyl acetate . As the domestic oriented mainly esterification, this process for the production of ethyl acetate is relatively mature, so this design uses the method of esterification. Then determine 2500t/a ethyl acetate workshop process. Through the use of materials conservation, energy conservation and other basic principles of computing, using the plate-by-plate caculation and other basic method design the size or type of the separating columns，heat exchangers and other equipments.，and determine the model. Key words: ethyl acetate; esterification; material balance; heat balance; workshop process design PAGE \* MERGEFORMAT I 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc359350868 第1章 绪论 PAGEREF _Toc359350868 \h 1 HYPERLINK \l _Toc359350869 1.1 产品的性质和用途 PAGEREF _Toc359350869 \h 1 HYPERLINK \l _Toc359350870 1.2乙酸乙酯的产能和市场需求 PAGEREF _Toc359350870 \h 2 HYPERLINK \l _Toc359350871 1.3产品的市场需求预测 PAGEREF _Toc359350871 \h 5 HYPERLINK \l _Toc359350872 第2章 乙酸乙酯的主要生产工艺 PAGEREF _Toc359350872 \h 8 HYPERLINK \l _Toc359350873 2.1乙酸/乙醇酯化法 PAGEREF _Toc359350873 \h 8 HYPERLINK \l _Toc359350874 2.2乙醛缩合法 PAGEREF _Toc359350874 \h 9 HYPERLINK \l _Toc359350875 2.3乙醇脱氢歧化法 PAGEREF _Toc359350875 \h 11 HYPERLINK \l _Toc359350876
