Modelagem, Simulação, Análise de estabilidade e Estatística de um Reator Químico Não Isotérmico

Abstract

The modeling and simulation of processes, presents itself as a powerful tool of extreme importance within the field of chemical engineering. By exploiting these resources, it is possible to predict and observe phenomena with accuracy and precision. This work aims to model, simulate and evaluate the stability of the production process of polystyrene, a thermoplastic of high commercial relevance. To perform the system evaluation, some statistical tools were used, in line with other mathematical tools, so that interdisciplinarity can be worked on. The proposal to control the process present in this work is different from the majority, as it aims to be a low-cost and easy-to-apply proposal. The methodology consists of three basic points, to perform the modeling, to find a stable operation zone, which can guarantee that despite the disturbances the process returns to its normal, and the making of the control charts from data obtained in the simulation. The proposed methodology proved to be efficient, considering that all the objectives of the present work were achieved and all stages of the methodology were concluded. Statistical analyzes provided information consistent with the dynamic behavior of the process, as well as the control charts proved to be effective in terms of monitoring and controlling the process, showing the effectiveness of the statistical tools.
