Estudio técnico–económico de una planta de generación eléctrica a base de biogás

Abstract

The landfill, Huascachaca Mines Santa Isabel Canton, Azuay Province, operating since 2008, has implemented a system for burning biogas capture and avoid direct emissions to air. The objective of this project is to present an alternative to the direct burning of biogas and use their flammable characteristics to produce electricity through the use of internal combustion engine and its own generator. Currently the average landfill reach 20 ton / day of waste, which means that the year 7300 will have tons, with an estimated increase of 20% annually. With this amount of waste is obtained 40m3 / h of biogas. Given that 1m3 of biogas produced at the landfill contains approximately 50% methane (CH4), which is 10Kwh/m3 calorific value, is to start producing electricity in 2014 using a 60kw generator power in the 2017 will increase 194kW generator, to give a total installed capacity of 254kW, then in 2020 and finally reach 448kW to 642kW in 2023. Amount to deliver to the local power grid and thus, part of the waste is transformed into clean energy. Additionally, biogas capture a significantly decrease pollution and odors in the area, as well as reduce the potential greenhouse has methane when injected directly into the atmosphere.
