SIMPLE EQUATION OF STATE ACCURATELY PREDICTS HYDROCARBON DENSITIES

Mohammad-Reza Riazi, G. Ali Mansoori University of Illinois at Chicago Chicago A simple, cubic equation of state (EOS) for hydrocarbon systems accurately predicts densities of a variety of hydrocarbons ranging from C1 to C40. The equation is simpler than typical industrial equations of state currently used. It produces an average error of 1.3% for density predictions of pure C1-C40 hydrocarbons and 1.7% for hydrocarbon mixtures (C1-C40) at pressures as high as 700 bar and temperatures of 1,000
