Evaluación del potencial de aprovechamiento energético del biogás residual generado por el relleno sanitario complejo ambiental Chasinato de la EPM-GIDSA

Abstract

Intergovernmental organizations in the fight against climate change developed several tools for estimating the production and emission of biogas in landfills. Focused on evaluating the energy using that the biogas produced in the Ambato’s landfill could provide this technical project searched to determine the estimated flow of biogas proposing alternatives for energy use and exposing the benefits in the generation of useful energy that the landfill gas should have for the city of Ambato. The estimation of the biogas flow generated by the landfill was determined through the application of the LandGEM model and the Ecuadorian model. Subsequently, a field measurement was carried out with a portable gas analyzer ÓPTIMA7 BIOGAS to determine the content of the biogas compounds and the calorific value of that. The Ecuadorian model was modified with the methane rate measured in-situ and the results of the three models were averaged obtaining an estimated flow of biogas recovered for the year 2021 of 365.40 cubic meters per hour and for the year 2029 of 522.33 cubic meters per hour. The potential for recovery of biogas for the year 2021 was 820 kW and 1180 kW for the year 2029. Several alternatives for energy use were proposed highlighting the ECOMAX5 BIOGAS cogenerator capable of producing 499 kW of useful electrical energy and 610 kW of total thermal energy in recovered water for industrial processes with a total efficiency of 83.1 percent.
