Assessing the performance of non‐associating <scp>SAFT</scp> ‐type equations of state to reproduce vapor pressure, liquid density, enthalpy of vaporization, and liquid heat capacity data of 1800 pure fluids

The performance of the PC-SAFT and I-PC-SAFT EoS in correlating P sat $$ {P}^{sat} , v liq {v}_{liq}^{sat} Δ vap H {\Delta}_{vap}H c {c}_{P, liq}^{sat} critical coordinates 1800 pure compounds that consist 1252 non-self-associating 548 self-associating is evaluated. equation able to reproduce data with a deviation close 1%, which meets highest standards. counterpart however large on pressure. exactly reproduces pressure temperature accurately correlates . Its weak point larger liquid density deviation. key conclusion this article absence correlation between strength association accuracy experimental were correlated. Regardless EoS, poor results are obtained for more than 15% but 60% correlated although no term was included considered EoS.
