摘要：

In this work, the Group Contribution Associating Equation of State (GCA-EoS) parameter table is extended in order to represent phase equilibrium behavior of aromatic compound mixtures, which contain the aromatic ether (ACOCH(3)), the phenol (ACOH) and the aromatic acid (ACCOOH) groups. Pure-group parameters and interaction parameters between these groups and the paraffin (CH3, CH2) and aromatic (ACH, AC, ACCH(3)) groups were estimated using experimental phase equilibrium data on binary mixtures. Also, their interaction parameters with water and carbon dioxide are reported. The extended parameter table is applied to predict high-pressure phase equilibria in binary and ternary mixtures containing high value complex aromatic compounds and carbon dioxide.
