Process design of ethylene oxide with annual

output of 30kt

Abstract:The process of ethylene oxide with annual output of 30,000 tons was designed in this paper. The process design of this essay introduced the epoxy ethane's properties, main uses, production situation, and point out the position and role of the epoxy ethane in national economy environment, in the main while it is analysis the industrial production method and development trend of epoxy ethane in the future. In this essay it is carefully compare many production methods and finally to choose the oxygen direct oxidation process method in the production of epoxy ethane with ethylene. And it is also describes the production principle and the production process. The material balance carries on the main equipment such as mixer, reactor and so

on.Then carry on the heat balance of epoxy ethane reactor equipment. And make the detailed calculating and checking of the epoxy ethane reactor equipment. Then make sure the operating parameters, decide the equipment type, and use of CAD drawing of the corresponding process flow diagram, at last to obtain the device parameters .

Key words : epoxyethane; process; reactor; material balance
