Considering nonideal behavior of fluids and its effects on hydrodynamic and mass transfer in multiphase flow is very essential. Simulations were performed that takes into account the effects of mass transfer and mixture nonideality on hydrodynamics reported by Irani et al. In this paper, by assuming the density of phases to be constant and Raullts law instead of using EOS and fugacity coefficient definition, respectively for both the liquid and gas phases, the importance of nonideality effects on mass transfer and hydrodynamic behavior was studied. The results for a system of octanepropane (T323 K, P 445 kpa) also indicated that the assumption of constant density in simulation had major role to diverse from experimental data. Furthermore, comparison between obtained results and the previous report indicated significant differences between experimental data and simulation results with more ideal assumptions.
