Resumo
Com a preocupação da indústria em realizar processos com custos reduzidos, qualidade
elevada e de forma sustentável, a destilação reativa tem recebido bastante atenção, por reunir
em um só equipamento, as duas operações mais importantes para a indústria química: a
destilação e a reação. Em relação aos processos convencionais, a destilação reativa tem
inúmeros benefícios, entre eles: economia de capital, aumento da conversão do processo e
maior sustentabilidade, pois as emissões gasosas são menores. O presente trabalho teve como
objetivo simular o processo de obtenção do acetato de metila por meio da reação de
esterificação entre o ácido acético e o metanol, na presença de catalisador de ácido sulfúrico e
utilizando uma coluna de destilação reativa em dois diferentes softwares livres, o COCO
Simulator e o Scilab, a fim de realizar uma análise comparativa dos resultados. Para que essa
análise fosse possível, um artigobase
foi selecionado e seu modelo foi reproduzido em ambos
os softwares. Algumas mudanças no modelo foram realizadas com o objetivo de conseguir uma
comparação direta entre o Scilab e o COCO Simulator e os resultados de ambos os softwares
foram semelhantes aos dados experimentais de literatura utilizados na comparação, sendo que
os resultados obtidos via COCO Simulator foram mais rigorosos do que os obtidos pelo Scilab
devido à consideração dos efeitos de calor na simulação do processo.
With the concern of the industry to carry out processes with reduced costs and high quality, in addition to being sustainable, reactive distillation has received a lot of attention, for bringing together in a single piece of equipment, two very important operations for the chemical industry: distillation and reaction. Compared to conventional processes, reactive distillation has numerous benefits, including capital savings, increased process conversion and greater sustainability, as gaseous emissions are lower. This work aimed to simulate the process of obtaining methyl acetate through the esterification reaction between acetic acid and methanol, in the presence of a sulfuric acid catalyst and using a reactive distillation column in two different free software, the COCO Simulator and Scilab, in order to perform a comparative analysis of the results. For this analysis to be possible a base article was selected, and its model was reproduced in both software. Some changes in the model were carried out with the objective of achieving a direct comparison between Scilab and COCO Simulator and the results of both software were like to the experimental data from the literature used in the comparison. The results obtained via COCO Simulator were more rigorous than those obtained by Scilab due to the consideration of heat effects in the process simulation.
