Destilação da Micela I: modelagem e simulação da evaporação do hexano

Abstract

In the soybean oil extraction process make the Micella that is a mixture of oil and hexane. The separation process in both components is named Micella Distillation. It is composed mainly of the hexane evaporation and of the hexane stripping. In this work, it was developed a mathematical modeling of the hexane evaporation. This model is based in mass and energy balances and in equilibrium relations. The validity of the model was made comparing the obtained results with data from a industry of the COAMO (Cooperativa Agrícola Mouraoense). In following, with the elaborated model, it was made the simulation of the evaporation to study: the influences of the temperature of the heating fluid and of the feed flow in the outlet evaporator concentration; the effects of the feed temperature, concentration and pressure over operation results of the evaporators; and, the comparison between the results considering the micella as real and ideal solution.
