Resumo: | HighlightsSimulation of acrylonitrile production processes.Simulation of utilities for more realistic results.Analysis of the gain in eco-efficiency considering five eco-indicators.The process with partial condensation step proved to be the most sustainable option.ObjectiveTo evaluate the gain in eco-efficiency by introducing a partial condensation step in the conventional acrylonitrile production process.MethodologyThe conventional and modified acrylonitrile production process, as well as the associated utilities plant, was simulated computationally using the UniSim Design Suite R390.1 software. Based on the results, five eco-indicators were developed (water, fuel and energy consumption, CO2 emission and liquid effluent generation), which were simultaneously evaluated through the Eco-efficiency Comparison Index of the considered processes.ResultsThe modification of the conventional process of acrylonitrile production, from the introduction of a partial condensation stage with the main purpose of reducing the consumption of process water, resulted in a 76% increase in eco-efficiency, considering the eco-indicators used in the study. The reduction in water consumption was evidenced by the calculation of the corresponding eco-indicator, which was 47% lower for the modified process.Limitations of researchEco-efficiency was evaluated, disregarding social and safety factors. In addition, the few data provided on the process and scaling of recovery section equipment, by the reference authors, limited the comparison of results.Practical implicationsThe paper presents a practical example of the use of eco-indicators in the analysis of the increase of eco-efficiency by the modification of industrial processes, mainly for the reduction of water consumption. Although the modification evaluated in this work has been implemented in an acrylonitrile production plant, the methodology can be applied in a similar way to other industrial processes.OriginalityThe present work shows a quantitative evaluation of the gain in eco-efficiency (notably with regard to water consumption) by the introduction of a partial condensation stage in the conventional acrylonitrile production process. |

Com base nos resultados, desenvolveram-se cinco ecoindicadores (consumo de água, combustível e energia, emissão de CO2 e geração de efluentes líquidos) que foram simultaneamente avaliados por meio do Índice Comparativo de Ecoeficiência dos processos considerados.ResultadosA modificação do processo convencional de produção de acrilonitrila, realizada a partir da introdução de uma etapa de condensação parcial com o intuito principal de reduzir o consumo da água de processo, resultou em um aumento de 76% na ecoeficiência considerando-se os ecoindicadores empregados no estudo. A redução no consumo de água foi evidenciada pelo cálculo do ecoindicador correspondente, que se mostrou 47% menor para o processo modificado.Limitações da investigaçãoA ecoeficiência foi avaliada desconsiderando-se fatores sociais e de segurança. Além disso, os poucos dados fornecidos sobre o processo e dimensionamento dos equipamentos da seção de recuperação, por parte dos autores de referência, limitou a comparação de resultados.Implicações práticasO trabalho apresenta um exemplo prático do uso de ecoindicadores na análise do aumento da ecoeficiência pela modificação de processos industriais, principalmente para a redução do consumo de água. Embora a modificação avaliada neste trabalho tenha sido implementada em uma planta de produção de acrilonitrila, a metodologia pode ser aplicada de maneira similar a outros processos industriais.OriginalidadeO presente trabalho apresenta uma avaliação quantitativa do ganho em ecoeficiência (destacadamente no que se refere ao consumo de água) pela introdução de uma etapa de condensação parcial no processo convencional de produção de acrilonitrila.ABEC2019-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/othertext/htmltext/htmlapplication/pdfapplication/pdfhttps://www.revistasg.uff.br/sg/article/view/145510.20985/1980-5160.2019.v14n1.1455Sistemas & Gestão; v. 14 n. 1 (2019): MARÇO 2019; 39-491980-516010.20985/1980-5160.2019.v14n1reponame:Sistemas & Gestãoinstname:Universidade Federal Fluminense (UFF)instacron:UFFporenghttps://www.revistasg.uff.br/sg/article/view/1455/htmlhttps://www.revistasg.uff.br/sg/article/view/1455/html_1https://www.revistasg.uff.br/sg/article/view/1455/pdfhttps://www.revistasg.uff.br/sg/article/view/1455/pdf_1Copyright (c) 2019 Sistemas & Gestãoinfo:eu-repo/semantics/openAccessBastião, Danyelle SoaresCaxiano, Igor NardiPrata, Diego Martinez2020-05-29T17:17:20Zoai:ojs.www.revistasg.uff.br:article/1455Revistahttps://www.revistasg.uff.br/sgPUBhttps://www.revistasg.uff.br/sg/oai||sg.revista@gmail.com|| periodicos@proppi.uff.br1980-51601980-5160opendoar:2020-05-29T17:17:20Sistemas & Gestão - Universidade Federal Fluminense (UFF)false |
