Abstract (English): Introduction. Dielectric oil is classified as a hazardous material by the EPA (Environmental Protection Agency of the United States of America). The oil is composed primarily of naphthenic, aromatic, and paraffinic hydrocarbons. With the continuous use of these oils in power equipment such as transformers and cables, reactions occur that create deposits on the equipment, making their renaturation costly. This article proposes a solvent extraction technique. A compact treatment plant was proposed to allow for the cost-effective and environmentally safe management of this type of hazardous waste. Objective. The objective of this research was to develop a treatment system for Fuller's earth contaminated with dielectric oil using solvent extraction with ethanol and TRITON to reduce the carbon footprint for users in the electrical industry. Methodology. The properties of the solvent, such as chemical affinity and boiling point, were evaluated while the contaminant was being removed. After treatment with the proposed system, the contaminated Fuller's earth met the cleanup standards required by current Colombian environmental regulations. To this end, a pilot treatment system was built to test the treatment process on 1 kg of contaminated Fuller's earth and evaluate the best alternative found in the reactor, using ethanol extraction. Results. The results of the study show that extraction with industrial-grade ethanol (96% purity) removed the greatest amount of dielectric oil. The amount in the soil after treatment averaged 0.5 ppm, the maximum value permitted by law (Resolution 1170 of 1997 of the Department of Environmental Management). Conclusions. The ethanol extraction process offers a new solution for the final disposal of Fuller's earth contaminated with dielectric oil, which until now has been carried out by incineration, and constitutes an environmentally friendly option for the management of hazardous waste.

Abstract (Spanish): Introducción. El aceite dieléctrico está clasificado como un material peligroso por la EPA (Agencia de Protección Ambiental de los Estados Unidos de América). El aceite está compuesto principalmente de hidrocarburos nafténicos, aromáticos y parafínicos. Con el uso continuo de estos aceites en equipos de potencia como transformadores y cables, se presentan reacciones que crean depósitos en los equipos, por lo cual su re naturalización es costosa. Este articulo propone una técnica de extracción con solventes. Para lo cual se propuso una planta de tratamiento compacta que permitiría la gestión de este tipo de residuos peligrosos de manera económicamente competitiva y ambientalmente segura. Objetivo. El objetivo de esta investigación fue desarrollar un sistema de tratamiento para tierra Fuller contaminada con aceite dieléctrico mediante extracción por solventes con etanol y TRITON para la reducción de la huella de carbono para los usuarios de la industria eléctrica. Metodología. Se evaluaron las propiedades del disolvente, como la afinidad química y el punto de ebullición, mientras se eliminaba el contaminante. Después del tratamiento con el sistema propuesto, la tierra contaminada de Fuller cumplió con los estándares de limpieza requeridos por las regulaciones ambientales colombianas actuales. Para ello, se construyó un sistema piloto de tratamiento para probar el proceso de tratamiento de 1 kg de tierra de Fuller contaminada y evaluar la mejor alternativa encontrada en el reactor, con extracción con etanol. Resultados. Los resultados del estudio muestran que la extracción con etanol de grado industrial (96% de pureza) eliminó la mayor cantidad de aceite dieléctrico. La cantidad en el suelo después del tratamiento promedió 0.5 ppm, el valor máximo permitido por la ley (Resolución 1170 de 1997 del Departamento de Administración Ambiental). Conclusiones. El proceso de extracción con etanol ofrece una nueva solución para la disposición final de la tierra de Fuller contaminada con aceite dieléctrico, que hasta ahora se ha realizado mediante incineración y constituye una opción ecológica para la gestión de residuos peligrosos.
