N2 - This study compares accuracies of PC-SAFT and its critical point-based revision (CP-PC-SAFT) with k12 = 0 along with the predictive 1978 Peng-Robinson EoS (PPR78) in estimating the available high-pressure phase equilibria data in binary systems of methane, ethylene, ethane, propane, and n-hexane with heavy branched, alkylbenzoic, bicyclic aliphatic and aromatic substances represented by squalane, n-dodecylbenzene, cis-decalin, tetralin, and naphthalene. Predictions of the pure compound properties of the considered heavy substances are evaluated as well. It is found that some data were predicted more accurately by CP-PC-SAFT and others-by Peng- Robinson EoS and PPR78. At the same time, the overall performance of PC-SAFT in predicting these data is found inferior in comparison with two other considered approaches.
