石化企业乙烯裂解系统能效评估方法研究

Study on energy efficiency evaluation method of ethylene cracking system in petrochemical enterprises

目前石化企业乙烯裂解的能效评估主要集中在单位产品能耗上,不能全面考核影响能效的相关因素。本文从经济、管理、生产、环保因素全面评估乙烯系统,建立了乙烯裂解的评估模型和评估方法,并提出了乙烯裂解系统的能效概念。能效评估方法在抚顺乙烯厂得到了应用,为全面评估石化企业乙烯裂解系统能效水平提供了理论依据。

At present,the energy efficiency evaluation of ethylene cracking in petrochemical enterprises is mainly focused onthe energy consumption of unit energy consumption,and the related factors that affect the energy efficiency can not be fully assessed.In this paper,the evaluation model and evaluation method of ethylene cracking were established from the aspects of economy,management,production and environmental protection,and the energy efficiency concept of ethylene cracking system was putforward. Energy efficiency evaluation methods in Fushun ethylene plant has been applied,and provides a theoretical basis for thecomprehensive assessment of petrochemical ethylene cracking system energy efficiency level.
