为了提高燃料乙醇生产企业的能量利用效率,本文针对以粮食为原料的典型燃料乙醇能量系统,以某企业为例开展了能流分析。首先运用e!Sankey软件绘制了详尽的企业能流图,在此基础上全面分析了能量流动和消耗的情况,计算出单耗及能量利用率等相关指标,识别出其中能耗高、能效低的薄弱环节。通过开展节能潜力分析,提出余热利用、工艺改进等系统节能的措施建议,预计可降低能耗约28%。以上分析方法对生物质能源产业的循环经济发展有指导意义。
In order to improve the energy efficiency of fuel ethanol producers, aiming at the typical fuel ethanol energy system using grain as raw material, an energy flow analysis is carried out in an enterprise. First, using e! Sankey software to draw a detailed enterprise energy flow diagram, on the basis of a comprehensive analysis of the energy flow and consumption, calculate the unit consumption and energy utilization and other related indicators, identify high energy consumption, low energy efficiency The weak link. Through the analysis of energy saving potential, proposed measures for energy saving of waste heat utilization and process improvement are estimated to reduce energy consumption by about 28%. The above analysis methods have guiding significance for the development of circular economy in biomass energy industry.
