High pressure (solid + liquid) equilibria of n-alkane mixtures: experimental results, correlation and prediction

The main aim of this work was to predict the SLE of the mixtures using only pure components data in a wide pressure range, far above the pressure range in which cubic equations of state are normally applied. The fluid phase is described by the corrected SRK-EOS using van der Waals one fluid mixing rules. The results of the predictions are compared with the experimental data presented in this paper {n-alkanes (n-tridecane, n-hexadecane, n-octadecane) + n-hexane} and with experimental results presented previously {n-alkanes (n-tridecane, n-hexadecane, n-octadecane and n-eicosane) + cyclohexane}.
