HERNANDEZ TOUSET, Juan Pedro  and  GUEVARA RODRIGUEZ, Jorge. Energy performance analysis at Heriberto Duquesne sugar mill. RTQ [online]. 2023, vol.43, n.2, pp. 421-436.  Epub May 30, 2023. ISSN 2224-6185.

One of the problems identified in the sugar industry is the deficient management of science and innovation. The objective of the research is to determine the potential savings of bagasse, fuel oil, steam and water in the raw sugar production process, through energy management, to increase energy efficiency indicators. A procedure is applied that includes the analysis methodologies of energy use analysis based on the energy review according to ISO 500001. The determination of 12 energy performance indicators, currently not reported for this industry, contribute to the definition of a line energy base and the systematic measurement of efficiency in industry. The general thermal efficiency, with a value of 77%, is affected by heat losses in the process, associated with heat recovery from hot streams, leaks and insulation, which can be reduced with energy integration to identify heat recovery potential. The modifications made to the energy system are of immediate economic recovery, given the significant potential savings of bagasse at the sugar mill and fuel at the distillery.
