Resumo: | In order to integrate different processes for the reuse of agricultural waste, the production of biogas and biofertilizer, produced by anaerobic digestion, are essential for the sustainable development and diversification of the Brazilian energy matrix. As the analysis of the thermodynamic performance of these systems is scarce in the literature, this work aimed to associate the physicochemical parameters of dairy cattle residues with the value of their respective chemical exergy. And thus, evaluate the efficiency of the biodigester based on real operational data from Starmilk, located in the municipality of Céu Azul in the west of the State of Paraná, Brazil. The results show that the exergy content of fresh manure was 16.03 MJ/kg, 15.35 MJ/kg for the biofertilizer and 29.55 MJ/m³ (CNTP) of biogas exergy. Based on the analyzes carried out, it is inferred that the analyzed biodigester has an overall exergy efficiency of 72.82%, being able to recover 27.29% of the exergy of cattle manure in the form of biogas. |

Dado que el análisis del desempeño termodinámico de estos sistemas es escaso en la literatura, este trabajo tuvo como objetivo asociar los parámetros fisicoquímicos de los residuos de ganado lechero con el valor de su respectiva exergía química. Y así, evaluar la eficiencia del biodigestor con base en datos operacionales reales de Starmilk, ubicado en el municipio de Céu Azul en el occidente del Estado de Paraná, Brasil. Los resultados muestran que el contenido de exergía del estiércol fresco fue de 16,03 MJ / kg, 15,35 MJ / kg para el biofertilizante y 29,55 MJ / m³ (CNTP) de exergía de biogás. De los análisis realizados se infiere que el biodigestor analizado tiene una eficiencia exergética global del 72,82%, pudiendo recuperar el 27,29% de la exergía del estiércol bovino en forma de biogás.No intuito de integrar diferentes processos de reaproveitamento de resíduos agropecuários, a produção de biogás e biofertilizante, produzidos pela digestão anaeróbia, são essenciais para o desenvolvimento sustentável e diversificação da matriz energética brasileira. Como a análise do desempenho termodinâmico desses sistemas é escassa na literatura, este trabalho teve por objetivo associar os parâmetros físico-químicos de resíduos da bovinocultura leiteira ao valor de suas respectivas exergia química. E assim, avaliar a eficiência do biodigestor com base em dados operacionais reais da Starmilk, localizada no município de Céu Azul no oeste do Estado do Paraná, Brasil. Os resultados mostram que o conteúdo exergético do dejeto fresco foi de 16,03 MJ/kg, 15,35 MJ/kg para o biofertilizante e 29,55 MJ/m³ (CNTP) de exergia do biogás. Com base nas análises feitas, infere-se que o biodigestor analisado possui uma eficiência exergética global de 72,82%, podendo recuperar 27,29% da exergia do estrume bovino na forma de biogás.Research, Society and Development2021-10-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2117010.33448/rsd-v10i13.21170Research, Society and Development; Vol. 10 No. 13; e276101321170Research, Society and Development; Vol. 10 Núm. 13; e276101321170Research, Society and Development; v. 10 n. 13; e2761013211702525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/21170/18906Copyright (c) 2021 Victor Vaz; Fabiane Mariah Bissani; Eric Valero Carvalho da Silva; Samuel Nelson Melegari de Souza; Bruna Bissani; Juliano de Souzahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessVaz, VictorBissani, Fabiane Mariah Silva, Eric Valero Carvalho da Souza, Samuel Nelson Melegari de Bissani, BrunaSouza, Juliano de 2021-11-21T18:26:28Zoai:ojs.pkp.sfu.ca:article/21170Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:40:39.088429Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
