Design of Dimethy1 Ether Production Process of 300,000 t/a
 
Abstract： This thesis represents the design of Dimethy1 Ether process of 300,000 t/a. The Dimethy1 Ether production processes developed in recent years are introduced and compared, the design employed by the pilot test of production technique of dimethyl ether from synthesis gas in a slurry reactor by FLOTU, in which coal-based syngas is used as raw materials, and byproduct methanol is produced at the same time.The whole report that mainly encompassed process designed by Aspen Plus, the material and heat balances, the heat integration by Aspen Pinch, the equipment design and selection, the automatic control of the equipment, the process flow diagram (drawings), the piping and instrument diagram drawings (ndrawings), the facility layout (AutoCAD drawings ), the plant layout (1 AutoCAD drawings ), safety and environmental documentation, marketing, investment and economic analysis. According to the 《Specification On Content and Procedure Preliminary Design File For Chemical Plant》, I complete documents consisting of storage, electricity, utility stations, fire fighting, water supply and drainage.

Key words: Dimethy1 Ether, Aspen Plus, AutoCAD, economic analysis , drainage
