Resumo: | Biogas has high potential to be used in the generation of electricity and heat and as a replacement for vehicular fuel, favoring the reduction of dependence on fossil fuels. In order for biogas to be used safely and effectively, H2S needs to be removed at levels tolerated for its intended purpose. The objective of this work was to evaluate the potential of a pilot scale scrubber to promote biogas desulfurization using the photosynthetic process with microalgae and the absorption process by washing with water at atmospheric pressure. The crude biogas presented H2S concentration above 1.000 ppm, by gas chromatography analysis. For the photosynthetic system with microalgae, the concentration of H2S in the purified biogas was reduced to 11 ppm with 30 minutes of operation and at 180 minutes it was completely removed, remaining so until the end of the daily cycle of system operation. For the water washing system, despite the concentration of hydrogen sulphide in the purified biogas having decreased considerably in the studied interval, an increase in the content was noticed over time, with readings ranging from 37,8 ppm to 188,4 ppm, indicating that there may be total saturation of this component, if the system works uninterruptedly. Thus, the removal of hydrogen sulphide through the biological process with microalgae was successfully performed in a pilot scale purifier, and its performance was classified as promising, providing appropriate conditions for desulfurization of biogas. |

Para que el biogás se use de manera segura y efectiva, el H2S debe eliminarse a niveles tolerados para el propósito previsto. El objetivo de este trabajo fue evaluar el potencial de un lavador a escala piloto para promover la desulfuración de biogás mediante el proceso fotosintético con microalgas y el proceso de absorción por lavado con agua a presión atmosférica. El biogás crudo presentó concentración de H2S superior a 1.000 ppm, por análisis de cromatografía de gases. Para el sistema fotosintético con microalgas, la concentración de H2S en el biogás purificado se redujo a 11 ppm con 30 minutos de operación y a los 180 minutos se eliminó por completo, permaneciendo así hasta el final del ciclo diario de operación del sistema. Para el sistema de lavado de agua, a pesar de que la concentración de sulfuro de hidrógeno en el biogás purificado disminuyó considerablemente en el intervalo estudiado, se notó un aumento en el contenido con el tiempo, con lecturas que van desde 37,8 ppm a 188,4 ppm, lo que indica que puede haber total saturación de este componente, si el sistema funciona ininterrumpidamente. Así, la remoción de sulfuro de hidrógeno a través del proceso biológico con microalgas se realizó con éxito en un purificador a escala piloto, y su desempeño fue catalogado como prometedor, brindando las condiciones adecuadas para la desulfuración del biogás.O biogás apresenta alto potencial para ser usado na geração de eletricidade e de calor e em substituição ao combustível veicular, favorecendo a diminuição da dependência por combustíveis fósseis. Para que o biogás possa ser utilizado com segurança e eficácia, o H2S precisa ser removido a níveis toleráveis para o fim a que se destina. O objetivo deste trabalho foi avaliar o potencial de um purificador em escala piloto para promover a dessulfurização do biogás, usando o processo fotossintético com microalgas e o processo de absorção por lavagem com água à pressão atmosférica. Os resultados das análises de cromatografia gasosa do biogás bruto mostraram concentrações de H2S acima de 1.000 ppm. Para o sistema fotossintético com microalgas, o teor de H2S no biogás purificado foi reduzido para 11 ppm com 30 minutos de operação e aos 180 minutos houve a remoção completa, permanecendo assim até o final do ciclo diário de funcionamento. Para o sistema de lavagem com água, apesar do gás sulfídrico no biogás purificado ter diminuído consideravelmente no intervalo estudado, percebeu-se o aumento do teor ao longo do tempo, com as leituras variando de 37,8 ppm a 188,4 ppm, indicando a possibilidade de ocorrência de saturação total deste componente, caso o sistema trabalhe ininterruptamente. Assim, a remoção do gás sulfídrico por meio do processo biológico com microalgas foi realizada com sucesso em purificador em escala piloto, sendo seu desempenho classificado como promissor, fornecendo condições apropriadas para dessulfurização do biogás.Research, Society and Development2022-08-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/3289110.33448/rsd-v11i10.32891Research, Society and Development; Vol. 11 No. 10; e388111032891Research, Society and Development; Vol. 11 Núm. 10; e388111032891Research, Society and Development; v. 11 n. 10; e3881110328912525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/32891/27899Copyright (c) 2022 Aline Antonia Castro; Estevan Luiz Junges; Munique Marder; Joice Mörs; Odorico Konradhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCastro, Aline AntoniaJunges, Estevan Luiz Marder, MuniqueMörs, JoiceKonrad, Odorico2022-08-12T22:23:03Zoai:ojs.pkp.sfu.ca:article/32891Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:48:43.762347Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
