Firstly, the properties, characteristics and production methods of olefins are discussed, and the process and advantages from methanol through dimethyl ether to olefins are analyzed to determine the DMTO process selected in this design. Inaddition, the design includes process design and calculation, equipment selection, workshop equipment layout design, automatic control, three wastes treatment, public engineering design and economic accounting. According to the principles of workshop layout and equipment layout in chemical plants, the layout of workshop facade and the size of key equipment are determined, and the automatic control, the treatment of three wastes and the consumption of public works are explained. Finally, according to the designed process route and the selected equipment, the process flow chart with control points, the layout of workshop facade and the assembly drawing of main equipment are drawn by AutoCAD. At the same time, the 20,000-word instructions are completed.
