In the soybean oil extraction process make the Miscella that is a mixture of oil and hexane. The separation process in both components is named Miscella 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 stripping. 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 stripping to study: the influences of the feed flow and the injection form of direct steam in the operation results of the stripper.
