北京理工大学珠海学院 2020 届本科生毕业设计年产 5 万吨丙烯腈生产工艺设计摘 要丙烯腈（AN）是一种广泛使用的化学原料，并用于各种生产领域，随着国内外对丙烯腈需求的增加，丙烯腈供不应求。大多数国内丙烯腈依靠进口产品来满足市场需求。当前，生产丙烯腈的方法是主要以丙烯、空气和氨为原料合成丙烯腈。此方法与以前的工艺方法相比，具有明显的优势，原料来源多、成本低廉、工艺简单。该设计将这个工艺的优势与 5 万吨/年丙烯腈合成工艺的设计主题相结合，以确定特定的工艺流程、工艺参数和相关设备。工艺参数的选择包括反应温度、反应压力、接触时间、进料纯度、比例以和催化剂。介绍了丙烯腈未来的发展前景、生产现状、生产原理及工艺流程的概述和工艺合成的基本方法，并且对设备进行物料和热量衡算以及主要设备的工艺计算。关键词：丙烯腈；丙烯氨氧化法；工艺计算 北京理工大学珠海学院 2020 届本科生毕业设计AbstractAcrylonitrile (AN) is a widely used chemical raw material and is used in various production fields. With the growing demand for acrylonitrile at home and abroad, the supply of acrylonitrile is scarce. Most domestic acrylonitriles depend on imported products to meet market demand. Currently, the acrylonitrile production method consists in synthesizing acrylonitrile mainly from propylene, air and ammonia. Compared to the previous process, this method has obvious advantages, with many sources of raw materials, low cost and a simple process. The design combines the advantages of this process with the design theme of the 50,000 ton / year acrylonitrile synthesis process to determine the specific process flow, process parameters and associated equipment. The choice of process parameters includes reaction temperature, reaction pressure, contact time, feed purity, ratio and catalyst. The prospects for future development, the state of production, the production principle and the overview of the acrylonitrile process flow and the basic method of process syn...
