A volume-translation function by the authors with arguments of reduced pressure and temperature was assessed for binary and multicomponent mixtures. The correlation is not a generalised function and reduced-pressure as an argument. Thereby, ensuring high performance at high pressure and temperature (HPHT) in the class of other volume-translation function for cubic equations of state. The function was compared to non-cubic equations of states (nCEoS) of PC-SAFT, GERG-2004, GERG-2008 and AGA8-DC92 for the prediction of molar-volume at HPHT with reasonable results.
