Simulation of Change in Density and Viscosity of Crude Oil When Mixing

The deviation of density and viscosity values oil mixtures from those calculated according to the additivity rule has been examined. Mathematical models have developed for determining properties with different compositions taking into account group composition source components. Mixtures containing components a high content alkanes low arenes found be characterized by extreme deviations towards maximum kinematic minimum. created were validated compared existing methods describing physicochemical properties. An approach creation optimal technological point view formulation compounding types is proposed.
