HERNANDEZ TOUSET, Juan Pedro et al. Energy analysis procedure for the conversion of sugar cane industries into biorefineries. Universidad y Sociedad [online]. 2021, vol.13, n.5, pp.277-288.  Epub 02-Oct-2021. ISSN 2218-3620.

The sugar mills present losses of energy resources in the generation, distribution, use of steam and in the administration of water, which affects the energy performance indicators and therefore the economy of the industry. An energy analysis procedure is shown and applied for the conversion of sugarcane industries into biorefineries. The aim of the study is to determine the energy performance indicators in an ethanol plant integrated into a biorefinery by means of a procedure for the analysis of energy use. Material and energy balances and Pinch Analysis method are applied with the use of HENSAD and Aspen Energy Analyzer for the design of the heat exchanger network. The procedure helps to meet important energy-related social and economic problems, still unresolved. Through energy integration, a recoverable energy potential is identified, which represents 71% of the maximum energy recovery in the ethanol plant. Fuel and water savings justify investment projects for improved heat recovery.

Palabras clave : Energy management; heat recovery; integration; ethanol.
