To improve the energy efficiency of fuel ethanol manufacturers, in this paper, taking an enterprise as an example, energy flow analysis was carried out based on a typical fuel ethanol energy system which used foodstuff as feedstock. By utilizing e! Sankey software, a detailed enterprise energy flow was drafted to analyze the direction and consumption conditions of energy comprehensively. And the weak links of large consumptive and inefficient energy utilization were identified through relevant index like unit consumption and utilization rate of energy. By means of the conducting potential analysis of energy saving, a 28% diminution system consumption of energy was estimated according to relevant suggestions and practices on utilizing wasted heat, production process improvement and etc. And all these analyses are about to guide the circular economy development of biomass energy industry.
