文档介绍：滁州学院本科毕业论文 1 年产万吨***叔丁基醚的工艺设计摘要: 本设计是年产万吨***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***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: ***叔丁基醚;异丁烯;甲醇; MTBE 工艺设计 Process design of an annual output of 40000 tons of methyl tert- butyl ether Abstract : The design is annual outputs of 40000 tons of methyl tart-butyl ether device production process design, mainly in the distillation process for process design; combined with the Anhui Zhonglian pany 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 ponents 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 bustion 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 滁州学院本科毕业论文 2 1绪论 MTBE 概述、理化性质、应用、在中国的发展 MTBE 概述***叔丁基醚, 英文缩写为 MTBE ( methyl tert-butyl ether ), 溶点-109 ℃, 沸点 ℃, 是一种无色、透明、高辛烷值的液体, 具有醚样气味, 是生产无铅、高辛烷值、含氧汽油的理想调合组份, 作为汽油添加剂已经在全世界范围内普遍使用。它不仅能有效提高汽油辛烷值, 而且还能改善汽车性能, 降低排气中 CO 含量, 同时降低汽油生产成本。另外, MTB E 还是一种重要化工原料, 如通过裂解可制备高纯异丁烯。 MTBE 是含氧量为 % 的有机醚类。它的蒸汽比空气重,可沿地面扩散,与强氧化剂共存时可燃烧。 MTBE 理化性质表 1-1MTBE 物理性质密度(kg/m3,20 ℃) 临界温度(°C)
