摘要：丙烯腈主要用于生产腈纶纤文，世界上其所占比例约为55%。我国用于生产腈纶的丙烯腈占80%以上。腈纶应用十分广泛，是继涤纶、尼龙之后的第3个大吨位合成纤文品种。其次，是用于ABS/AS塑料。由丙烯腈、苯乙烯和丁二烯合成的ABS塑料和由丙烯腈与苯乙烯合成的AS塑料是重要的工程塑料。因该产品具有高强度、耐热、耐光和耐溶性能较好等特点。与丁二烯共聚制丁腈橡胶也是丙烯腈的主要用途之一。丙烯腈也是重要的有机合成原料。丙烯腈经催化水合可制得丙烯酰胺,经电解加氢偶联可制得己二腈，丙烯酰胺主要用于纸张、废水处理、矿石处理、油品回收、三次采油化学品方面。此外，丙烯腈还可用来生产医药、高分子絮凝剂、纤文改性剂、纸张增强剂等。丙烷氨氧化法目前有两种工艺流程，一是丙烷在催化剂作用下，同时进行丙烷的氧化脱氢和丙烯氨氧化反应，称为丙烷一段氨氧化法；二是丙烷经氧化脱氢后生成丙烯，然后以常规的丙烯氨氧化工艺生产丙烯腈，称为丙烷两段氨氧化法。本设计采用丙烷一段氨氧化法。

With an annual output of 80000 tons of acrylonitrile process design
Abstract： Acrylonitrile mainly for the production of acrylic fiber and its proportion in the world is about 55%. Used in the production of acrylic acrylonitrile accounted for more than 80% of our country. Acrylic is widely used, it is the third big tonnage after polyester, nylon synthetic fibers. Next, it is used for ABS/AS plastic. By acrylonitrile, styrene and butadiene synthesis of ABS plastic and synthesized from styrene and acrylonitrile AS plastic is an important engineering plastics. Because the product has high strength, heat resistance, light resistance and solvent resistance performance is good wait for a characteristic. With the copolymerization system of butadiene nitrile rubber is also one of the main purposes of acrylonitrile. Acrylonitrile is important raw material in organic synthesis. Acrylonitrile acrylamide, via catalytic hydration can be obtained by electrochemical hydrogenation coupling can be obtained adiponitrile, acrylamide is mainly used for paper, waste water treatment, ore processing, oil recovery, eor chemical aspects. Moreover, acrylonitrile can also be used to produce medicine, high polymer flocculant, fiber modifier, paper strengthening agent, etc. Propane ammoxidation method there are two processes, one is the propane in the role of catalyst, at the same time on the oxidation of propane dehydrogenation and propylene ammonia oxidation reaction, call a period propane ammoxidation method; 2 it is generated after oxidative dehydrogenation of propane to propylene, and then in the usual propylene ammonia oxidation process production of acrylonitrile, called propane ammoxidation method two pieces. This design adopts the propane period of ammonia oxidation process.
