Analysis of biogas production from agricultural waste by monitoring the variables of temperature, pressure and pH in an Anaerobic Biodigester in the rural area of Ocaña Análisis de la producción de biogás a partir de desechos agrícolas mediante la supervisión de las variables de temperatura, presión y pH en un Biodigestor Anaeróbico en la zona rural de Ocaña

Abstract

Colombia faces an environmental problem due to population growth, generating an increase in agricultural and organic waste. The methodology of this research focuses on a supervision system that allows identifying key variables such as temperature, pressure and humidity contained in the production of biogas. To determine the analysis of these variables, an energy balance is carried out in the biodigester. The main objective of this project is to regulate the organic load from agricultural components, which is usually released directly into water courses and open fields. The study allowed finding pressure values ​​that ranged between 0.8 to 1 PSI, according to the amount of biomass contained in the biodigester, the pH ranged around 0.6 to 0.8 to maintain the microorganisms that produce the biogas and The temperature increases due to the charging time between 35 to 40°C, contributing to greater efficiency and energy balance. In conclusion, if these values ​​are maintained in the production of biogas, it allows a positive impact on the environment and a great contribution to the energy transition process that is implemented in the country.
