In this investigation, two alternatives to improve a pilot plant for the integral use of oranges were evaluated from the exergetic point of view. The case study was based on information provided by the project "Integrated Evaluation with Sustainability Criteria, of the Process of Extraction by Steam Drag of Essential Oil from Orange Peel (Citrus Sinensis) of the Valleys of the Province of Arequipa, in the Perspective of its Commercial Use”, in which the improvement of the pilot plant was recommended. In the best scenario (using two preheaters), there was a greater decrease in the exergy destroyed both in the plant and in the equipment associated with the stages of the process, and an even greater decrease in fuel consumption. As a complement to this research, a thermoeconomic analysis was carried out in order to establish the effects of the proposed plant configurations on exergetic costs.

En esta investigación se evaluaron desde el punto de vista exergético dos alternativas para mejorar una planta piloto para el aprovechamiento integral de la naranja. El estudio de caso se basó en información proporcionada por el proyecto “Evaluación Integrada con Criterios de Sostenibilidad, del Proceso de Extracción por Arrastre a Vapor de Aceite Esencial de Cáscara de Naranja (Citrus Sinensis) de los Valles de la Provincia de Arequipa, en la Perspectiva de su Uso Comercial”, en el que se recomendaba la mejora de la planta piloto. En el mejor de los escenarios (utilizando dos precalentadores) se presentó una mayor disminución de la exergía destruida tanto en la planta como en los equipos asociados a las etapas del proceso y una disminución aún mayor en el consumo de combustible Como complemento a esta investigación, se realizó un análisis termoeconómico con el fin de establecer los efectos de las configuraciones de planta propuestas sobre los costos exergéticos.
