Thermodynamic modeling of several alcohol-hydrocarbon binary mixtures at low to moderate conditions
2021
Abstract This study aims to precisely model vapor phase concentration and bubble pressure in correlating alcohol-hydrocarbon mixtures to accurate assessment with effects from literature by employed Patel-Teja equation of state and together with Wong-Sandler mixing rules. Even though other intricate equations have been used for some selected systems, it is the first time that a systematic approach for measuring hydrocarbon-alcohol mixtures in the range of low to moderate pressures has been practiced by this research. Results show that models employed in this work, average-absolute deviations are fewer than the previous EoSs for alcohol-hydrocarbons binary mixtures. The complex models calculate bubble pressure and vapor phase concentration respectively with 2.25% and 3.25% of average-absolute deviations, whiles our models show a better result for them (respectively, 0.00 % and 0.47% averagely).
