| Descripción: |
A new vapor-liquid equilibrium apparatus was constructed to measure temperature, pressure, and phase compositions up to 8 MPa. Systems of CO(,2) with 2-methyl-1-pentene, 1-hexene, 1-heptene and m-xylene were studied at 303.15 K, 323.15 K, and 343.15 K. A general method was proposed for equation of state construction. Two equations of State were constructed. Using critical temperature, critical pressure, critical compressibility factor and acentric factor, these equations can predict saturation properties of normal fluids. The equations were extended to mixtures using van der Waals' one fluid theory, Lee-Kesler corresponding state approach and a virial-like approach. They had limited predictive abilities compared to cubic equations. A correlation for third virial coefficients of nonpolar gases was developed. The correlation requires the knowledge of critical temperature, critical pressure and acentric factor and is applicable to mixtures of nonpolar gases including quantum gases. Predictions are in good agreement with reported experimental data. |
