| dc.description | A thermodynamic method to check the consistency of phase equilibrium data developed by the authors and applied to several situations by different researchers is analyzed to determine the effect of the equation of state employed to correlate the data on the final response of the consistency test. The consistency test method, in fact, uses an equation of state to correlate the equilibrium data and to calculate some properties such as volume, fugacity and compressibility factor. After these properties are determined the Gibbs-Duhem equation is applied to determine data consistency. If the data fulfill the Gibbs-Duhem equation the data are considered to be consistent and if the data do not fulfill de Gibbs-Duhem equation the data are of doubtful thermodynamic consistency. The equation of state dependency of the method has been recognized by the authors and other researchers but discussion of the real effects of the equation of state used on the results of the consistency method has not been presented. This work demonstrates that after a good and accurate thermodynamic model is used to correlate the data, the consistency test can be considered equation-of-state independent. (C) 2017 Elsevier B.V.
