Abstract

The sugar mill lacks a process to identify the potential for thermal energy recovery and to define energy performance indicators. The objective of the research is to evaluate the use of thermal energy and the potential for heat recovery for the definition of improvements in the energy scheme of the sugar mill. A procedure is applied that includes methods of energy use analysis according to ISO 50001 standard and process integration methodologies using Aspen Energy Analyzer software. The current energy scheme satisfies both the demand for waste steam and secondary steam for the technological equipment and allows the distribution of 24 t/h of waste steam for the alcohol distillation process. The definition of 15 energy performance indicators which are not currently reported for this industry, contribute to the definition of an energy baseline and the systematic measurement of industry efficiency for continuous improvement. The current network of heat exchangers recovers 100 % of the energy and its thermal design is appropriate.
