Vapor-liquid equilibrium of binary systems containing low GWP refrigerants with cubic equations of state

Different Cubic Equations of State (CESs) were used to represent Vapor-Liquid Equilibrium (VLE) of binary systems containing low Global Warming Potential (GWP) refrigerants. The calculated VLE data from some of the widely used CESs were compared with the experimental data collected from the literature. To extend CESs to binary systems, van der Waals one-fluid mixing rules with a single binary interaction parameter were used. Although the deviations between the experimental and calculated values are generally low, a comparison of the results was performed to find the most accurate CES for VLE of the studied binary systems.
