    This design focuses on the choice of synthetic scheme, first introduced the status of methanol industry at home and abroad, the source of methanol raw materials and the nature and use of methanol itself. Secondly, the basic principle of methanol synthesis is introduced, which influences the factors of methanol synthesis and the reaction rate of methanol synthesis. In the synthesis program which mainly introduces the raw material route, different raw materials methanol method, the synthesis of methanol three methods, the choice of production scale, improve production technology to carry out energy saving, the introduction of foreign advanced control technology to further improve the control level, To develop China's methanol industry and simple flow chart. In the process conditions, the main introduction of the temperature, pressure, hydrogen and carbon monoxide ratio and space velocity. The main equipment of the cold-excited adiabatic reactor and the tube-type isothermal reactor introduced. Finally, a simple material balance.
