Based on that, its possible to highlight hydrous ethanol, which is used as fuel for vehicles, the pharmaceutical industry, alcohol and beverages. However, the purification of hydrous ethanol becomes an important step for its applications. Therefore, for the development of hydrous ethanol purification a conventional distillation was used to physically separate miscible mixtures from each other. In order, to verify the dynamics of the distillation columns, Aspen Plus Dynamics was used to evaluate six control strategies and four tuning rules for three distillation columns, in order to verify the best strategy and apply to hydrous ethanol 92.5%, 93.6% and 94.6% by mass of ethanol, according to ANP. Thus, from the dynamic study using Aspen Plus Dynamics, it was possible to verify that the Ziegler-Nichols, Cohen Coon and ITAE methods showed good results, being similar, in which they chose to select the Ziegler-Nichols method. And among the control strategies, the double compositions presented better results to the disturbances performed in the flow and feed composition.Acesso AbertoEtanolDestilaçãoAspen plus dynamicsSimulação dinâmicaColuna de destilaçãoEthanolDistillationAspen plus dynamicsControlTuning rulesTrabalho de Conclusão de CursoEngenhariasEngenharia Química
