Aprovechamiento energético de aceites usados y su contribución a la sustentabilidad ambiental mediante el coprocesamiento en hornos cementeros.

Abstract

The objective of this study was to evaluate the scope for energy recovery from waste oils generated by the Riobamba city car park and its contribution to environmental sustainability though co-processing in cement kilns. The substitution of used lubrication oils generated by automotive sources as part of the fuel handled in cement kilns is a strategy that improves processing against a final disposal of this type of highly contaminant hazardous waste. The study tested the characteristics of the used lubricating oils generated by the city of Riobamba determining that its physicochemical composition is suitable to an energy recovery, via a percentage being utilized in the fuel injection system of the cement kiln belonging to the Compañía de Economía Mixta (UCEM CEM) Chimborazo Plant. The results of the testing yielded a heat output of 9312 Kcal / kg of the mixture used oil and cement kiln fuel. The substitution of a percentage of the used lubricating oils from automotive sources in the city of Riobamba, will generate the least environmental impact before a final disposition of this type of waste, a management model that would be sustainable based on a policy in force at the national level. A medium-term projection of its investments is recommended to ensure that the project could obtains additional benefits that would justify its implementation.
