PERFORMANCE ASSESSMENT OF TAO-MASON EQUATION OF STATE: RESULTS FOR VAPOR-LIQUID EQUILIBRIUM PROPERTIES
The present work assesses the performance of a molecular based equation of state known as Tao-Mason (TM) equation of state in predicting thermodynamic properties of fluids in a very wide range of temperatures encompassing 100K<T<1100K and pressures ranging from zero to 3200 bar. The twenty one fluids including: argon (Ar), krypton (Kr), xenon (Xe), nitrogen (N2), oxygen (O2), carbon dioxide (CO2), methane(CH4), ethane (C2H6), propane(C3H8), normal butane (n-C4H10), isobutene (i-C4H10), ethen (C2H4), benzene (C6H6), toluene (C7H8) as well as refrigerants including 1,1,1,2 tetra fluoroethane (R134a), Tetrafluoromethane (R14), chlorodifluromethane (R22), 1,1,1 Trifluoroethane (R143a), 1,1,1trifluoro, 2,2dichloroethane (R123), Octafluoropropane (R218), and 1,1 difluoroethane(R152a) are selected and compared with literature data. The calculations cover the ranges from the dilute vapor or gas to the highly compressed liquid and supercritical region. The thermodynamic properties are the vapor and liquid densities and the vapor pressure. It is found that the overall agreement with literature in all phases especially the vapor/gas phase is remarkable.
