Otimização energética em sistemas de combustão multicombustível

Abstract

This work addresses the energy optimization of a multi-fuel system based on environmental and economic paradigms. To achieve this, a multi-objective linear mathematical programming modeling is proposed, enabling optimal solutions for the problem. Additionally, a dedicated multi-criteria decision aid strategy is suggested to support decision-making. This strategy considers specific commercial attributes of the problem using the Analytic Hierarchy Process (AHP) method. The proposed global tool proved to be of great value for identifying solutions with low environmental impact, becoming essential for companies that want to be more efficient and competitive in the market. It is relevant to highlight that, in the case studied, this tool made it possible to notice a solution that, at first, could be mistakenly discarded if the observer were guided only by the final production. Indirectly, the solution achieved resulted in a gain of 9.0 Mcal/h compared to the standard solution, in addition to the potential reduction of 8.43 Ton/h in the emission of CO2 and the financial return from reducing the consumption of unnecessary inputs in the scope analyzed.
