Resumo: | Adequate knowledge of biodiesel’s physical properties is necessary to simulate and optimize its process obtaining, mainly the chemical reactor. The objective of this work was to evaluate predictive models of physical properties of methyl and ethyl esters that compose biodiesel to model reactor. Although some experimental data are available, their determination for all the existing biodiesel components can be expensive and complex. Thus, this work investigated the performance of group contribution and approach by fragments in the calculation of these properties. The properties evaluated in this study were: normal boiling temperature, critical temperature, critical pressure, critical volume, acentric factor, saturation pressure, liquid density, enthalpy and Gibbs energy of formation, viscosity, cetane number, cold flow properties and flash point. For each property evaluated was recommended of the most feasible model by comparing estimated values to experimental data available in the literature. Therefore, a database of these properties was created to use in engineering applications. |

O conhecimento adequado das propriedades físicas do biodiesel é necessário para simular e otimizar seu processo de obtenção, principalmente o reator químico. O objetivo deste trabalho foi avaliar modelos de predição de propriedades físicas de ésteres metílicos e etílicos que compõem o biodiesel para modelagem de um reator. Embora alguns dados experimentais estejam disponíveis, a determinação para todos os componentes existentes no biodiesel pode ter alto custo e ser uma tarefa complexa. Portanto, este trabalho investigou modelos de contribuição de grupos e abordagem por fragmentos no cálculo dessas propriedades. As propriedades avaliadas foram: temperatura normal de ebulição, temperatura crítica, pressão crítica, volume crítico, fator acêntrico, densidade, entalpia de vaporização, entalpia e energia de Gibbs de formação, viscosidade, número de cetano, propriedades de fluxo a frio e ponto de fulgor. Para cada propriedade avaliada, foi recomendado o modelo mais viável, comparando-se os valores estimados aos dados experimentais disponíveis na literatura. Assim, foi criado um banco de dados dessas propriedades para uso em aplicações de engenharia.Universidade Federal de Viçosa - UFV2020-06-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/1003110.18540/jcecvl6iss2pp0179-0188The Journal of Engineering and Exact Sciences; Vol. 6 No. 2 (2020); 0179-0188The Journal of Engineering and Exact Sciences; Vol. 6 Núm. 2 (2020); 0179-0188The Journal of Engineering and Exact Sciences; v. 6 n. 2 (2020); 0179-01882527-1075reponame:The Journal of Engineering and Exact Sciencesinstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/jcec/article/view/10031/5717Copyright (c) 2020 The Journal of Engineering and Exact Sciencesinfo:eu-repo/semantics/openAccessSilva, Gisele Cristina RabeloCaño de Andrade, Maria Helena2021-02-23T20:11:24Zoai:ojs.periodicos.ufv.br:article/10031Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/oai2527-10752527-1075opendoar:2021-02-23T20:11:24The Journal of Engineering and Exact Sciences - Universidade Federal de Viçosa (UFV)false |
