乙二醇装置改造方案探讨

介绍了中国石化北京燕山分公司化工一厂，乙二醇装置的现状。从规模、技术、市场三方面论证了装置改造的必要性。从平衡原料乙烯的需要、发展下游产品的需要、满足国内市场的需求及技术经济上分析了装置改造的可行性。制定了停产乙二醇，改产环氧乙烷的改造方案。改造项目的实施，既可以优化产品结构，多生产高附加值产品，又可使装置的蒸汽用量、冷却水用量、总用电量降低，装置能耗下降，企业经济效益得到提高。

Discussion on Modification Plan of Ethylene Glycol Plant

This paper introduces the current status of Yanshan ethylene glycol plant ,demonstrates the necessity of plant modification from aspects of scale ,technology and market.The paper also analyzes the feasibility of plant modification from viewpoints of the requirements of balancing ethylene feed,developing downstream products,meeting the demand of domestic market,and technical economy.The paper gives a modification plan for changing the product from ethylene glycol to ethylene oxide from the plant .The modification project can not only optimize the product structure,produce more high value added products,but also lower the steam consumption ,cooling water consumption and overall power consumption of the plant,thus reducing the energy consumption of the plant and improving the economic benefits of the enterprise.
