摘要
针对炼油行业、石油化工行业和煤化工行业能效评价指标各自独立、互不兼容的现象,建立了单位工业增加值能耗评价指标和相应计算方法来衡量能源化工企业(或装置)的用能水平,为能源化工行业提供了一种能效评价和对标管理的手段。按照不变价格体系和市场价格体系平均值计算:DCC-PLUS(增强型催化裂解)装置与MIP(多产异构烷烃的催化裂化)装置相比,单位原料综合能耗高86%,单位工业增加值能耗仅高28%;CVMTO(煤经甲醇制烯烃)工艺和CVOTO(煤经费托合成油制烯烃)工艺相比,单位产品综合能耗低37%,单位工业增加值能耗低48%。基于市场价格体系比较,CVOTO工艺比CVMTO工艺的单位原料增加值高4.41元/t原料,单位工业增加值能耗低1 833.73 MJ/t原料。
Energy consumption per unit industrial value added and its corresponding calculation method have been established so as to solve the problem that the existing energy efficiency evaluation indexes in oil refining, petrochemical and coal chemical sectors are mutual independent and incompatible. It provides a better alternative means of energy efficiency evaluation and benchmarking management for energy and chemical industry. The case study shows that based on the average value of constant price system and market price system, the comprehensive energy consumption per unit feedstock of DCC-PLUS unit is 86% higher than that of MIP unit, and its energy consumption per unit industrial value added is only 28% higher;the comprehensive energy consumption per unit product(ethylene and propylene) of CVMTO process is 37% lower than that of CVOTO process, and its energy consumption per unit industrial value added is 48% lower. However, based on market price system, the unit feedstock value added of CVOTO process is 4.41 yuan per ton higher than that of CVMTO process, and the energy consumption per unit industrial value added is 1 833.73 MJ per ton feedstock lower.
