Estimation of binary interaction parameters of different equations of state using ethane experimental solubility data in N-methyl-2-pyrrolidone (NMP) solvent

Application of CP-PC-SAFT and PC-SAFT for Simultaneous Prediction of LLE and High-Pressure VLE with Universal k12 Values in Systems of Gases and n-Alkanes with N-Methyl-2-pyrrolidone and Some Substituted Aromatic Compounds

“…Such references are Murrieta-Guevara et al, 21 Lazzaroni et al, 22 and Tian et al 23 Thus far, some of these data were modeled using different thermodynamic approaches. In particular, several studies 16,[18][19][20][21][22]24 correlated the experimental VLE data of the considered systems using various cubic equations of state (EoSs) and mixing rules. Gonzaĺez et al 25 demonstrated that although the DISQUAC model is more accurate than UNIFAC in estimating the LLE of alkane−NMP systems, it still incorrectly represents a dependence of their upper critical solution temperatures (UCSTs) on the n-alkane carbon numbers and cannot yield simultaneously accurate results for the VLE and LLE with the same sets of interaction parameters.…”
