This design is the preliminary design of the chloroethanol synthesis section with an annual output of 50000 tons. Firstly, the domestic and foreign research and development of the products are introduced. Secondly, the selection of plant site, the properties and specifications of raw materials and products are introduced. Through the comparison of a variety of process routes and comprehensive consideration, this design uses ethylene oxide method to produce chloroethanol. The material balance, heat balance and Aspen Plus simulation of the whole process are carried out. The distillation column was calculated in detail, and the sensitivity of the distillation column was analyzed. At the same time, the corresponding auxiliary equipment was calculated and selected. According to the design principles, the safety and environmental protection and economic accounting are briefly summarized, and the graduation design specification is completed. According to the design requirements, Auto CAD is used to draw the process flow chart with control points, the plane and elevation of the workshop and the schematic diagram of main equipment.
