Abstract: The processing of national petroleums causes many operational problems due to the asphaltene aggregation phenomena. To evaluate the behavior of these phenomena, a study based on optical scan technique was carried out to understand the behavior of pure oils and their mixtures. The evaluation according to criteria established by ASTM D7061-06 1 gives a result of asphaltene flocculation of according to the separability number. In this study, the aspects related to the existence of colloidal forms of peptized asphaltenes in distinct solvents present in petroleums can cause changes in the kinetics of asphaltene flocculation.
