【正文】 。芳烴的抽提是煉油通向化工的一座橋梁，它不僅可以降低汽油中的苯含量，提高汽油的質(zhì)量， 保護(hù)其人類賴以生存的環(huán)境，更重要的是：它能提供高純度的苯、甲苯、二甲苯等基本有機(jī)化工原料，來滿足日益增長的石油化學(xué)工業(yè)與化學(xué)纖維工業(yè)的需要。但隨著煉油工業(yè)和化學(xué)工業(yè)的發(fā)展，在現(xiàn)代 煉廠中，催化重整裝置的重整生成油和乙烯裝置副產(chǎn)的裂解汽油是生產(chǎn) BTX的主要原料。預(yù)計(jì)至 2020年將分別達(dá)到 Mt、 、 ，全世界平均年需求增長率仍保持在 4％ 以上 [1]。隨著石油化工產(chǎn)業(yè)及紡織工業(yè)的不斷發(fā)展，世界上對芳烴的需求也在不斷增長。 關(guān)鍵詞 ： 芳烴 ；芳烴抽提 ； 催化重整；四乙二醇醚 齊齊哈爾大學(xué)畢業(yè)設(shè)計(jì)（論文） Ⅱ Abstract This article is about the first step design of the extraction section for the catalyst reforming plant with a capacity of 300000 t∕a. Firstly, It discusses the aim of the extraction section, the domestic and overseas developing condition,the parison of the extraction solvent and the process, the market prospect and production 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 20200 words design specification has also been finished. Key words: Aromatics； Aromatic hydrocarbon extraction； Catalytic reforming； Glycofurol 齊齊哈爾大學(xué)畢業(yè)設(shè)計(jì)（論文） Ⅱ 目 錄 摘 要 ......................................................................................................................................
