乙烯工业是石油化工中的核心也是高耗能行业,评价乙烯企业的用能水平是实现节能降耗的基础。本文针对乙烯企业的能效分析问题,基于数据包络分析(DEA),提出了一种面向整厂级别的能效分析方法。该方法综合乙烯生产的各项投入产出计算其能效。并基于该方法利用Matlab Web Server构建了B/S架构的乙烯能效分析系统,实现了多个乙烯企业横向及纵向的能效分析,为企业了解其能效水平及趋势提供了参考依据。
Ethylene industry is the core of petrochemical industry is also a high energy-consuming industries, evaluate the level of energy use of ethylene enterprises is to achieve the basis of energy saving. In this paper, aiming at the problem of energy efficiency analysis of ethylene enterprises, an energy efficiency analysis method oriented to the whole plant level is proposed based on data envelopment analysis (DEA). The method integrates various inputs and outputs of ethylene production to calculate its energy efficiency. Based on this method, the B / S ethylene energy efficiency analysis system was constructed by using Matlab Web Server, which realized the horizontal and vertical energy efficiency analysis of several ethylene enterprises and provided a reference for enterprises to understand their energy efficiency level and trend.
