Abstract

The PT equation of state is used in this paper to calculate the thermodynamic properties of propane and carbon dioxide binary mixture. The properties of the mixture of propane and carbon dioxide with three different composition are also studied using PT equation of state and van der Waals mixing rules. The calculating data are compared with the data obtained using software NIST REFPROP 8.0. Results show that the maximum relative error of properties for both saturated liquid and saturated gas is less than 1.471%. And the minimum average relative error is 0.177%. And the maximum average relative error is 0.799%. The computation is accomplished by the program with Visual interface, which makes the calculation process more convenient. And the results are with high precisions.
