摘要

为有效分析乙烯生产装置的能效状态，评价乙烯行业的能效水平，并寻找提高乙烯能效的改进方法，提出了一种基于IDA-DEA的乙烯行业能效评价方法。首先运用IDA分解方法获得影响能源消耗的活动、结构与强度3个能源绩效指标（EPI）；然后使用基于投入-产出松弛变量的数据包络分析方法（DEA）对活动、结构与强度能源绩效指标进行分析，得到提高乙烯装置能效和产量的改进方向；最后，为提高乙烯装置生产提供操作指导。实验结果验证所提方法的可行性和有效性，为石化行业节能降耗提供了新思路。

Abstract

In order to effectively analyze ethylene plant's energy efficiency status

evaluate ethylene industry's energy level

and improve the energy efficiency

this paper proposes an energy efficiency evaluation method of index decomposition analysis based data envelopment analysis including slack variable in ethylene industry. In the proposed method

firstly

the IDA method is used to acquire the three energy performance indexes of the influencing energy consumption

i.e.

activity effect

structure effect

and intensity effect. Then by analyzing the three energy performance indexes

the DEA method based on slack variable is used to obtain a strategy for improving ethylene energy efficiency and production. Finally

the operation guidance can be applied to enhance the production efficiency of ethylene plants. The results verified the feasibility and effectiveness of the IDA-DEA evaluation method and the proposed IDA-DEA method provides a new idea for saving energy in the petrochemical industry.
