产万千吨之环氧乙烷工艺设计.docVIP

內容摘要 本文是對年產5.5萬噸環氧乙烷/乙二醇車間環氧乙烷合成工段的工藝設計。本設計依據中國石油天燃氣有限責任公司撫順石化乙烯分廠環氧乙烷生產工段的工藝過程，在實際生產理論的基礎上，制定合理可行的設計方案。 本文主要闡述了環氧乙烷在國民經濟中的地位和作用、工業生產方法、生產原理、工藝流程。採用excel工作表對主要設備如：混合器、反應器、環氧乙烷吸收塔、二氧化碳吸收系統，環氧乙烷解吸塔，冷凝器，脫輕組分塔等進行物料衡算，對環氧乙烷反應器，進料-產品第一換熱器，冷卻器等六個設備進行熱量衡算，並對環氧乙烷反應器和換熱器進行設備計算。對脫輕組分塔進行了詳細的設備計算和校核，確定了指令引數、設備類型和材質，使用CAD繪製相應的工藝流程圖。最後對此工藝過程可能存在的安全隱患及相應措施做了簡要說明。 關鍵字：環氧乙烷；工藝流程；反應器； 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.
