年产 3000 吨氯甲烷氯化吸收工段工艺设计摘要甲烷氯化物是化工生产中重要的原料和有机溶剂，在现代化工工业中有着重要的作用。许多具有各种重要用途的氯化产品可以从氯化工业中获得，氯化工业还促进了其他化工工业的发展。甲烷氯化物的发展对我国化工工业和国民经济的发展具有深远的影响和意义本设计项目是年产 3000 吨氯甲烷氯化吸收工段工艺设计，参照国内氯甲烷氯化的技术和方法来设计本次工艺，以及结合其他工艺的优点来制定设计方案。本设计主要是吸收工段的工艺设计，氯甲烷氯化反应产生的尾气主要是酸性气体，包括氯气、氯化氢、二氧化碳等。本设计工艺采用水洗法和碱洗法对尾气进行处理。关键词：氯甲烷氯化吸收工段设计 水洗法 碱洗法Process design of chloromethane chlorination absorption section with an annual output of 3000 tonsAbstractThe products of chloromethane chloride are dichloromethane, trichloromethane and chloroform, which are important chemical raw materials and solvents. Many chlorinated products with various important uses can be obtained from the chlorination industry, which also promotes the development of other chemical industries. [2]The production process design is based on the technology and method of chloromethane chlorination in China and the advantages of other processes. The design is mainly the process design of the absorption section. The tail gas from the chlorination of chloromethane is mainly acid gas, including chlorine, hydrogen chloride, carbon dioxide, etc. In this design, the tail gas is treated by water washing and alkali washing.Key words: Design of chloromethane chlorination absorption section water washing alkali washing method目录1 绪论...............................................................................................................................................11.1 项目建设目的和意义............................................................................................................11.2 市场初步预测分析.......
