A method was developed for varying the ratio of paraffinic/naphthenic and aromatic hydrocarbons in petroleum disperse systems by introducing a model dispersion medium and for noting the dynamics of change of petroleum disperse system composition in a triangular diagram. Data for the construction of the system phase equilibrium curves were derived and the phase equilibrium of atmospheric resids, cracked tars, and pyrolysis tars was evaluated. Disruption of phase equilibrium upon introducing a precipitant led to coagulation of the asphaltenes and their separation from the deasphalted product phase in precipitate form. The method can be used in determining the quantity of precipitant required to achieve the necessary depth of deasphalting or to determine deasphalting depth with a given precipitant consumption.
