HERNANDEZ TOUSET, Juan Pedro  e  SOSA GOMEZ, Eliani. Energy performance analysis in a raw sugar refinery. RTQ [online]. 2022, vol.42, n.3, pp. 590-606.  Epub 15-Out-2022. ISSN 2224-6185.

Process Integration combine several processes to reduce consumption of resources and harmful emissions, becoming an important asset in ensuring the sustainability of industrial processes. This paper aims to set energy performance indicators of a cane sugar refinery. A procedure that includes the energy analysis and Pinch Analysis methodologies is applied, with the use of HENSAD. Targets and energy performance indicators, currently not reported for this refinery, contribute to the definition of an energy baseline and the systematic measurement of efficiency.

There is an excess in thermal power duty of 32,5 MW with respect to the minimum heating duty, which determines the research into retrofit designs of the heat exchanger network. Annual savings of 1 010 571 USD estimated in energy analysis and heat integration make the evaluation of investment projects in the energy area feasible.

Palavras-chave : heat integration; sugar cane; energy; pinch analysis.
