Implementation of the critical point-based revised PC-SAFT for modelling thermodynamic properties of aromatic and haloaromatic compounds

摘要: Abstract The current study aims at assessing universality of the recently proposed generalized predictive critical point-based PC-SAFT EoS (CP-PC-SAFT). Phase equilibria and single phase thermodynamic properties aromatic compounds their mixtures are compared with available experimental information in a wide range reaching times pressures 6000 bars super-critical temperatures, while covering nearly 9000 data points. It is demonstrated that spite significant density variations, under consideration can be included applicability CP-PC-SAFT. In addition, this model an effective estimator mixtures. However major drawback CP-PC-SAFT underestimation vapour away from A conceptually different approach, namely Hybrid Group-Contribution (H-GC-PC-SAFT, Burgess et al., 2014) considered as well. Although often less precise than CP-PC-SAFT, several cases, such low temperature pressures, it exhibits noticeable advantages.
