Abstract
The concept of energy efficiency when applied in industries can result in significant economic and environmental gains. In most of these plants, there is the demand for thermal and electric energy, making cogeneration systems an adequate application, especially when it comes to food industries. In its processes, there is the generation of waste and effluents with high organic load that need adequate treatment, which is often biodigestion with the formation of biogas. However, for existing cogeneration, the insertion of biogas as a fuel is possible under different energy arrangements, requiring an evaluation of the model that provides the highest energy efficiency. Thus, the present work seeks to determine the most technically adequate energy system for the existing cogeneration of a food industry considering the insertion of biogas as fuel through simulations in GateCycleTM software. In addition, the most cost-effective energy arrangement was evaluated considering the costs of implementation and maintenance. As a result, all the proposed arrangements are technically viable. However, the one that brings the best financial return to the investor is the insertion of the biogas in the existing boiler, having its co-combustion with biomass.
