Abstract

A new analytical hybrid method for calculating enthalpy difference in mixtures is presented in this paper. The method is based on the Peng-Robinson cubic equation of state (PR CEOS), it is a combination of two common enthalpy calculation methods, and it does not require any experimental data. The &agr; function of the PR CEOS for every component is selected among several models. The new hybrid method results of 8 different mixtures are compared to data from the REFPROP™ database, and a satisfying agreement is obtained.
