Thermodynamic modeling of wax disappearance temperature in n-alkane mixtures by perturbed hard sphere chain equation of state

In this study, the perturbed hard sphere chain equation of state (PHSC EoS) has been used for the prediction of the wax disappearance temperature (WDT) in n-alkane mixtures. The PHSC EoS can thermodynamically predict the properties of high-molecular-weight compounds and chain-like molecules. The WDT of binary and ternary n-alkane mixtures have been predicted thermodynamically without using any fitting parameter. The liquid and solid phases are described by PHSC EoS based on multi-solid phase theory. The results have shown that the PHSC EoS is capable to predict the WDT of a n-alkane mixture by reasonable accuracy in comparison with experimental data.
