Initially, biogas was generated with organic wastes (whey, meat, cereals) produced in the Agroindustrial complex by characterizing the mixture of experimental raw materials in an accredited laboratory, obtaining a pH 6; COD 5855; BOD5; 1148; dissolved solids 4345; PM biodegradability of 0.19, complying with the basic stimulating standards for anaerobic fermentation/digestion. An A*B factorial design was carried out, with three study factors Factor A: Agroindustrial waste S+L, Factor B: Hydraulic retention time (HRT), Factor C: Temperature (T), giving us a design of 12 treatments with three replicates each, working with 36 experimental units. An ANOVA analysis was used to determine the three best treatments T4, T16, T28 with a mixture of (10% S + 90% L), a HRT of 30 days and a temperature of 20ºC. he three best treatments were replicated in the field and subjected to a physical-chemical analysis with specialized equipment (GA5000). The parameters measured were CH4 and CO2, resulting in the best treatment T16: 73.77% methane gas and 22.5% CO2, H2S hydrogen sulfide gas and water vapor are no longer present because iron filings and bio carbon filters were used. With the percentage of methane available from the three best treatments, the calorific value T4 2429.88 MJ/m3, T16 2640.85 MJ/m3, T28 2226.93 MJ/m3 and the power T4 0.32kWh/year, T16 0.35kWh/year, T28 0.29kWh/year were calculated. The electricity obtained was analyzed economically based on the cost of implementing the best Biodigester and the cost of a generator to transform the mechanical energy into electrical energy, giving us a total of $235 and compared with an average plant energy consumption of $30 per month; the useful life of a Biodigester built with the materials used can last approximately 5 years in which the electrical energy consumption would be $.. |
