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. [ABSTRACT FROM AUTHOR]

Se describe la evaluación tecnológica de la planta cubana de papel Papelera Pulpa Cuba a fin de estimar la factibilidad de un sistema para el procesamiento de sus aguas residuales. Se caracterizaron los procesos mediante diagramas fuente-sumidero y se simuló la recuperación de agua y fibra con el sistema propuesto de recuperación de aguas residuales. Los resultados indican buenos beneficios en materia de ahorro de agua fresca y energía.
