N2 - Hydrofluoroolefins(HFOs) have been proposed as promising candidates for alternative refrigerants. In this work, a comprehensive comparison of the performance of the Cubic Plus Association (CPA) and (perturbed-chainstatistical associating fluid theory) (PC-SAFT) equations of state for six thermodynamic properties of HFOs is presented, in which 11parameter estimation methods are considered and analyzed. On the basis of the comparison with experimental data and a theoretical analysis, a method meeting both satisfactory results and simplicity is recommended for parameter estimation for this type of compounds. The results show that both CPA and PC-SAFT perform equally well for the prediction of vapor pressure, liquid density, and speed of sound in the gas phase. CPA provides better isobaric heat capacity predictions compared to PC-SAFT irrespectively of the estimation method used, but PC-SAFTpresents the best overall performance when all properties are considered.
