Resumen en español

Cogeneration systems are now increasingly appearing in the industrial and commercial sector, since their implementation brings with it a number of energy, economic and environmental benefits. This makes a study of the general operation of the cogeneration system implemented with a biogas-fueled ICM and coupled to an absorption refrigeration system, which is a very useful application of this type of system. The objective of this work was to perform an energy analysis of the entire cogeneration system. The development of this strategy begins with the definition of the operating parameters in the engine, and then the modeling of the system using the ASPEN HYSYS® computational tool. Subsequently, a parametric analysis of the output variables in the system is presented. The results show that if an adequate selection of the methane composition in the fuel is made and the optimal operating parameters are adjusted in the ICM, good results can be obtained, being possible to implement them in real industrial applications.
