Abstract

In this paper, the refinery stage technological design of epoxyethane /ethylene glycol workshop was described, which was based on the output of 55,000 ton epoxyethane per year. This design was based on the technics process of China Petroleum and natural gas limited liability company in Fushun Ethylene Plant workshop, the feasible design scheme was set down according to the theory of practicality production.

In this paper, the position and the function in the national economy, the produce methods in industry, the principle of produce, process were interpred. For the main equipments such as:mixtor, reactor, the absorb tower of epoxyethane,the absorb system of carbon dioxide,the stripper of epoxyethane,condenser, the dehydrogenation components of the tower etc. calculating of material balance were done by using microsoft excel, calculation of energy balance were carried on for the epoxyethane reactor, heat exchanger,and condenser etc six equipments in all. And equipment calculations for reactor, heat exchanger etc .The dehydrogenation components of the tower were carried on detailed equipment calculations and checking. The parameters, equipments types and material were confirmed, by using CAD corresponding technics process chart for the high purity epoxyethane rectifier was draw. Finally, a brief explanation to the most possible existed dangers and correspond measures for the production process were given. Keywords: epoxyethane; process; reactor;
