PAGE PAGE 12 Mt/a甲基叔丁基醚装置的工艺设计摘要：本设计是年产2Mt/a甲基叔丁基醚装置生产工艺设计，主要以精馏工段为工艺设计对象， 结合了安徽中联能源有限公司年产3.0万吨MTBE项目的基础上，按任务要求生产量设计此工艺流程。此反应采用的合成工艺是汽油经脱丙烷后的混合成分中的异丁烯与甲醇在强酸性苯乙烯系阳离子交换树脂催化剂上进行反应生成MTBE。随着我国国民经济和轿车行业的发展，加上国家对无铅汽油的禁止使用，作为环保型无铅汽油主要添加剂的甲基叔丁基醚，不仅能有效的提高汽油的辛烷值和汽油燃烧效率，并且减少有害气体的排放，还可有效改善汽油的冷启动特性和加速性能，对气阻无不良影响，因此其其社会需求量与日俱增。关键词：甲基叔丁基醚；异丁烯；甲醇；MTBE工艺设计The design process of 2 Mt/a methyl tert butyl ether deviceAbstract: The design process of 2 Mt/a methyl tert butyl ether device production process design, mainly in the distillation process for process design; combined with the Anhui Zhonglian Energy Company Limited annual production capacity of 30000 tons of MTBE project according to the task requirements, design the production process. The synthesis process of this reaction is used in gasoline by isobutene and methanol mixture components after depropanizer in strongly acidic styrene was the reaction of MTBE cation exchange resin catalyst. With the rapid development of our national economy and the car industry, together with the national ban on the use of unleaded gasoline, methyl tert butyl ether environment-friendly lead-free gasoline as main additive, not only can effectively improve the octane number of gasoline and gasoline combustion efficiency, and reduce the emission of harmful gases, the cold start characteristics can effectively improve the gasoline and the acceleration performance, no adverse effect on the air resistance, so its social demand grow with each passing day Key Words：Methyl tert-butyl ether；Isobutene ；Methanol; MTBE process design目 录TOC \o 1-3 \h \u HYPERLINK \l _Toc3834 一、绪论 PAGEREF _Toc3834 6 HYPERLINK \l _Toc20951 1.1MTBE概述、理化性质、应用、在中国的发展 PAGEREF _Toc20951 6 HYPERLINK \l _Toc30293 1.1.1MTBE概述 PAGEREF _Toc30293 6 HYPERLINK \l _Toc1865 1.2 MTBE工艺设计依据、技术来源、合成工艺 PAGEREF _Toc1865 8 HYPERLINK \l _Toc18449 1.2.1 MTBE工艺设计依据 PAGEREF _Toc18449 8 HYPERLINK \l _Toc7679 1.2.2技术来源 PAGEREF _Toc7679 8 HYPERLINK \l _Toc14801 1.2.3本次设计采用的合成工艺 PAGEREF _Toc14801
