| 摘 要： | 为了有效评价乙烯行业的能效水平,寻找能效改进机会,针对乙烯装置数据特点,结合能源消耗中的活动影响、结构影响与强度影响等因素,提出基于能源绩效指标(EPI)的乙烯行业能源效率评价方法。在能效分析的基础上,结合数据包络分析(DEA)方法,将能效指标与产物收率综合进行分析评价。最后,给出了针对若干装置能源数据的分析评价实例,实验结果验证了该方法的准确性与有效性,为乙烯装置效率评价提供了新思路。

| Abstract: | In order to effectively evaluate ethylene industry’s energy efficiency level,and search for an opportunity to improve the energy efficiency,an ethylene industry’s energy efficiency evaluation method based on energy performance index(EPI)is proposed in this paper,which is according to data’s characteristic of the ethylene industry,and considers the activity effect,structure effect,intensity effect of energy consumption.Then the EPI and ethylene yield with data envelopment analysis(DEA)are analyzed.Finally,an example based on the energy data of several ethylene plants is presented.The results verify the accuracy and validity of the method and provide a new way to evaluate the efficiency of ethylene plants. |
