Resumo: | Non-ionic surfactants are important chemical products, they are raw materials in the production of solvents, detergents, paints etc. They are produced through the ethoxylation reaction, that takes place in semi-batch reactors, by reacting between ethylene oxide with an organic substrate in the presence of a basic catalyst such as KOH. Due to the instability and reactivity of ethylene oxide, ethoxylation is a highly exothermic reaction, which requires the presence of a heat exchange system, with strict control of temperature and pressure that prevents explosions. In this paper, the ethoxylation of nonylphenol to obtain nonylphenol 9 EO (nonoxynol 9) was simulated in Aspen Plus Dynamics® where temperature, pressure, and batch flow controls were implemented and evaluated. The results obtained showed that the control from the response of ∆P (difference between the operating limit pressure and the real reactor pressure) is effective, consequently, the reactor pressure remains controlled and lower than the limiting pressures of the system throughout the reaction process. |

Debido a la inestabilidad y reactividad del óxido de etileno, la etoxilación es una reacción altamente exotérmica, que requiere la presencia de un sistema de intercambio de calor, con un estricto control de temperatura y presión, que evite explosiones. En este trabajo, se simuló la etoxilación de nonilfenol para obtener nonilfenol 9 EO (nonoxinol 9) en Aspen Plus Dynamics®, donde se implementaron y evaluaron controles de temperatura, presión y flujo de lote. Los resultados obtenidos mostraron que el control a partir de la respuesta de ∆P (diferencia entre la presión límite de operación y la presión real del reactor) es efectivo, en consecuencia, la presión del reactor se mantiene controlada y por debajo de las presiones límite del sistema durante todo el proceso de reacción.Os surfactantes não iônicos são importantes produtos químicos, pois são matéria-prima na produção de solventes, detergentes, tintas etc. São produzidos através da reação de etoxilação, realizada em reatores semi-batelada, a partir da reação entre o óxido de etileno e um substrato orgânico, na presença de um catalisador básico como o KOH. Devido à instabilidade e reatividade do óxido de etileno, a etoxilação é uma reação altamente exotérmica, onde se faz necessário a presença de um sistema de troca térmica, com um rigoroso controle de temperatura e pressão para que explosões não ocorram. Neste trabalho, a etoxilação do nonilfenol, para obtenção do nonilfenol 9 EO (nonoxynol 9) foi simulada no Aspen Plus Dynamics® onde foram implementados e avaliados controles de temperatura, pressão e vazão da batelada. Os resultados obtidos mostraram que o controle a partir da resposta de ∆P (diferença entre a pressão limite de operação e a pressão real do reator) é eficaz, fazendo com que a pressão do reator permaneça controlada e menor que as pressões limites do sistema ao longo do processo de reação.Research, Society and Development2022-01-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2569210.33448/rsd-v11i2.25692Research, Society and Development; Vol. 11 No. 2; e27511225692Research, Society and Development; Vol. 11 Núm. 2; e27511225692Research, Society and Development; v. 11 n. 2; e275112256922525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/25692/23027Copyright (c) 2022 Heloísa do Nascimento Souza; Karoline Dantas Brito; Carla Gabriela Azevedo Misael; Renata Caroline de Farias Gonçalves; Romildo Pereira Britohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSouza, Heloísa do Nascimento Brito, Karoline Dantas Misael, Carla Gabriela Azevedo Gonçalves, Renata Caroline de Farias Brito, Romildo Pereira 2022-02-07T01:42:50Zoai:ojs.pkp.sfu.ca:article/25692Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:43:55.026715Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
