A procedure was developed to characterize the C/sub 7+/ fraction of bitumen for the Peng-Robinson (PR) equation-of-state (EOS) and to predict multicomponent diluent/bitumen mixture phase behavior. The results showed that the procedure can predict accurately not only the bubble-point pressures but also the atmospheric flash compositions at surface facilities and reservoir conditions. In this procedure, new correlations for the acentric factor and the PR EOS interaction coefficients for high molecular weight components were developed. The sensitivities of the EOS predictions to the number of pseudocomponents and the corresponding critical properties and acentric factors were analyzed. The results also indicated that the critical temperature and the acentric factor of the C/sub 7+/ fraction have a strong influence on the bubble-point pressure predictions. As for the prediction of the flash compositions, the number of pseudocomponents and the interaction coefficients have the strongest influence.
