Implementación de un Biodigestor para producir Biogás a partir de los residuos orgánicos generados en el Centro de Faenamiento Municipal Tena, Napo

Abstract

A floating dome biodigester was implemented as one of the influential measures in the agricultural and environmental fields to produce biogas from organic waste generated by ruminants. The research was conducted in the facilities of Slaughtering Tena (CEFATE-CEM), Tena City, Napo Province, to develop the production of biogas from organic waste generated by 15 heads of cattle getting 30 % of the company which biogas will be used only to scorch the legs of cattle. To design efficient digester model, comparisons of various investigations are made, in different conditions such as temperature, humidity, pressure etc. Resulting in one ideal model called floating dome biodigester or Hindu which can capture a volume of organic matter of 18 m 3 with an output of 10 m 3 of biogas generating a total of 277,2 m 3 of biogas per month with a production of rumen and manure of 15 head of cattle. The operating conditions of the biodigester is performed with a temperature ranging from 25 to 35 degrees Celsius, a retention time of 30 days due to the experiments performed in situ and a pressure of 57,91 Kpa per month, these data are obtained by installing a flow meter and pressure gauge inside incurred in the operation where the exact amount that enters to the biodigester weighs 300 Kg and 300 L will be added corresponding, because 1 Kg of manure is equal to 1 L water, obtaining a mixture of 600 Kg a day, so once it enters to the biodigester proper control of pH, temperature, pressure, gas flow, laboratory analysis of organic matter and biological was performed as final product for irrigation in different areas. The biodigester had an effectiveness of 87 % which met the company ́s requirements with the production of biogas for singeing process, values represented with a volume of 277,2 m 3 per month, so it generates a total of 8 gas tanks monthly. Quality control and revision of the digester is recommended to maintain balance in the processes that are generated in it.
