This work assesses the ability of the Mattedi-Tavares-Castier (MTC) equation of state (EOS) in representing the liquid phase density, sound speed, and vapor pressure of linear alkanes (C6-C20). It is found that its deviations from experimental data for liquid phase density, liquid phase sound speed, and vapor pressure are similar to, yet slightly higher than, those of the PC-SAFT EOS for the same compounds. Using only experimental data points at reduced pressures smaller than 20 for parameter fitting, a condition observed in most commercial chemical processes, leads to smaller deviations from the experimental values. Adopting for the lattice cell volume the value of 15 cm(3)/mol, which is the molar volume of the methylene group in the lattice-based UNIQUAC model, all the adjustable MTC EOS parameters follow regular trends with respect to the number of carbon atoms in the linear alkane chains. These parameters could be fitted to empirical expressions. When used, they produce deviations in pure-component liquid phase density, liquid phase sound speed, and vapor pressure equal to 0.6, 2.8, and 9.8%, respectively. The results for binary mixtures are generally in good agreement with the experimental data.
