Aprovechamiento energético de aceites usados y su contribución a la economía circular mediante elcoprocesamiento en hornos cementeros

Abstract

The aim of this research was to evaluate the energetic utilization of waste-oils, generated by the Riobamba city car park and its contribution to environmental sustainability, through co-processing in cement kilns. On the other side, to realize an energy valorization identifying the technology of co-processing in cement kilns, proposing alternatives of environmental sustainability, through a system of management before the final disposition of used oils in plants of cement production. The research employed the Variance Analysis (ANOVA) as the methodological strategy, as a suitable alternative for the development of variables of the physical-chemical composition of waste oils above co-processing and environmental sustainability criteria. The results show an optimum mixture that complies with physico-chemical properties for the proposed co-processing in the rotary Clinker kiln of UCEM CEMC Chimborazo Factory.In addition, ananalysis of the income of the project was made, proving that it is a profitable project and therefore financially feasible.
