Resumo: In the present work simulations were performed to compare the results obtained, in terms of product compositions, with those present in the literature for this type of reaction and also to evaluate the influence of these results on the energy capacity of the products. The simulations were performed with the aid of Aspen Plus® simulation software, simulating the operation in a Gibbs Reactor. The simulated pressure and temperature conditions, which corresponded to those used in the literature to enable the comparison of results, were altered in order to identify their influence on the process. The data generated in the simulations was analyzed and, based on it, we were able to determine as ideal conditions of pressure and temperature 382 ºC and 0.14 MPa; in addition to the ideal composition of each polymer to be fed into the reactor (51% PE, 41% PP and 8% PS); the energy self-sufficiency of the process, using the gaseous stream of pyrolysis products to generate energy capable of melting the reactor supply current and supplying the energy requirement of the reactor: and the system's ability to produce useful work, through the application of  an Otto cycle, in the amount of 3,615 kW / kg.

As simulações foram realizadas com o auxílio do software de simulação Aspen Plus®, simulando a operação em um Reator de Gibbs. As condições de pressão e temperatura simuladas, que corresponderam àquelas usadas na literatura para viabilizar a comparação de resultados, foram alteradas de modo a se identificar a influência das mesmas no processo. Os dados gerados nas simulações foram analisados e a partir deles foi possível determinar como condições ideais de pressão e temperatura 382 ºC e 0,14 MPa; além da composição ideal de cada polímero a ser alimentada no reator  (51% PE, 41% PP e 8% PS); a autossuficiência do processo, em termos energéticos, utilizando a corrente gasosa dos produtos da pirólise para gerar energia capaz de fundir a corrente de alimentação do reator e suprir a necessidade energética do mesmo e a capacidade do sistema de produzir trabalho útil, via aplicação de um ciclo Otto, no valor de 3,615 kW/kg.Universidade Federal de Viçosa - UFV2021-05-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/1257810.18540/jcecvl7iss2pp12578-01-19eThe Journal of Engineering and Exact Sciences; Vol. 7 No. 2 (2021); 12578-01-19eThe Journal of Engineering and Exact Sciences; Vol. 7 Núm. 2 (2021); 12578-01-19eThe Journal of Engineering and Exact Sciences; v. 7 n. 2 (2021); 12578-01-19e2527-1075reponame:The Journal of Engineering and Exact Sciencesinstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/jcec/article/view/12578/6646Copyright (c) 2021 The Journal of Engineering and Exact Scienceshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessAnunciato, Taiza CassiaCazarini, VitóriaFernandez, Yamila Guadalupe ToroMoraes, Nathalia Lara deFranco, Ivan CarlosMiraldo, Igor Ocasaque de Freitas Balieiro2021-07-05T18:18:27Zoai:ojs.periodicos.ufv.br:article/12578Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/oai2527-10752527-1075opendoar:2021-07-05T18:18:27The Journal of Engineering and Exact Sciences - Universidade Federal de Viçosa (UFV)false
