Potential of biogas production in an anaerobic digester solar assisted

Abstract

This article discusses an installation of anaerobic biodigestion aided by a heating system using solar energy to maintain the temperature inside the digester above the ambient temperature and thus increase the production of methane which can be used as fuel. The facility is located in Mexico City. In experimental tests a temperature difference of 10.14 ° C between the temperature inside the digester and room temperature was obtained. These results imply a potential for improvement in the production of biogas and methane yield of 16.6%. This improvement was achieved due to the use of the solar collector. The implementation of this technology involves stop issuing 13983.15 kg (CO2) per year for a 150 l digester volume operation.
