It is very important in national economy. In recent years, with the development of the products that are made from methanol, especially the popularization and application of the fuel of ethanol, the demand for the ethanol rises by a large margin. In order to satisfy economic developments demands for methanol, the t/a ethanol project is carried out. The main content of the design process is craft prove, material balance, heat balance etc. The principle of the design is in line with the national conditions, advanced in technology, accessible, comprehensive utilization of resources, as well as economic and environmental. This design mainly adopts the following process: coke oven gas as raw materials, tube average temperature ethanol synthesis reactor at low pressure, the rectification craft of two towers for rectifying ethanol. In addition, controlling of waste emissions strictly, the full use of waste heat, reducing energy consumption, staff safety and health are well considered.
