“…In particular, in chemical engineering thermodynamics subjects, students must to master not only the conceptual aspects of thermodynamic properties, but also how to estimate them with adequate thermodynamic models. Thus, one can find several computer programs that are excellent teaching tools, and many modern textbooks (Sandler, 2006) include some programs in user-friendly software or in spreadsheets (Castier, 1999) Several studies have implemented Mathematica programs to use or solve equations of state along the vapor-liquid equilibrium curve (Polishuk and Yona, 2009;Polishuk et al, 2009aPolishuk et al, , 2009b or to calculate different thermodynamic properties of interest (Castier, 1999;Domínguez and Castier, 2002;Macedo et al, 2008;Alfradique et al, 2002;Castier and Amer, 2011).…”

We present a simple program written in Mathematica 8.0 that permits using a general analytical expression to accurately correlate different thermodynamic properties of a saturated pure fluid. In particular, the program permits one to obtain simple analytical expressions for the liquid density, vaporization enthalpy, surface tension, and the inverse of the isobaric heat capacity of a saturated liquid as a function of the temperature along the entire vapor-liquid coexistence curve. The general expression used is the same for all four thermodynamic properties. It takes the values at both critical and triple temperatures as referents and four or fewer adjustable coefficients for each property. The program displays the absolute and relative errors together with wide information about the error distribution. It can be therefore used as a research or a pedagogical tool.

This study demonstrates that the overall reliability of a simplest cubic equation of state (EOS) might be improved by developing its accuracy in estimating the virial coefficients. In particular, it has been demonstrated that the progress can be achieved in predicting the sound velocities and, probably, the Joule−Thomson inversion curves. At the same time, the limitations of the simplest model are evident. In particular, it fails in predicting of the virial coefficients in the low temperature range. As a result, its predictions of the liquid phase properties are still imperfect. Further directions of development of the proposed EOS are discussed.
