“…The liquid densities reported by Shaver et al [21] are lower than those of Reamer and Sage [17] with the largest differences near the critical point. The liquid compositions reported by Shaver et al [21] agree with all of the published data sets within 0.005 mole fraction CO 2 except those of Chou et al [22]. The vapor phase compositions reported by Shaver et al [21] are in good agreement with those of Nagarajan and Robinson [18] at low pressures, but differences near the critical point are about 0.006 mole fraction CO 2 .…”

“…We have used the same apparatus to measure C V for the CO 2 + n-decane mixture. Prior to this work, some thermodynamic properties of CO 2 + n-decane mixtures have been reported by other investigators [20][21][22][23][24][25][26]. However, most of the available PVTx and VLE data cover only limited ranges of temperature, pressure, and concentration.…”

Isochoric Heat Capacity of CO2 + n-Decane Mixtures in the Critical Region

The isochoric heat capacity of two binary (CO 2 + n-decane) mixtures (0.095 and 0.178 mole fraction of n-decane) have been measured with a hightemperature, high-pressure, nearly constant volume adiabatic calorimeter. Measurements were made at nineteen near-critical liquid and vapor densities between 87 and 658 kg · m −3 for the composition of 0.095 mole fraction n-decane and at nine densities between 83 and 458 kg · m −3 for the composition of 0.178 mole fraction n-decane. The range of temperatures was 295 to 568 K. These temperature and density ranges include near-and supercritical regions. The measurements were performed in both one-and two-phase regions including the vapor + liquid coexistence curve. The uncertainty of the heat-capacity measurements is estimated to be 2% (coverage factor k = 2). The uncertainty in temperature is 15 mK, and that for density measurements is 0.06%. The liquid and vapor one-(C V 1 , C V 1 ) and two-phase (C V 2 , C V 2 ) isochoric heat capacities, temperatures (T S ), and densities (ρ S ) at saturation were measured by using the well-established method of quasi-static thermograms for each filling density. The critical temperatures (T C ), the critical densities (ρ C ), and the critical pressure (P C ) for the CO 2 + n-decane mixtures were extracted from the isochoric heat-capacity measurements on the coexistence curve. The observed isochoric heat capacity along the critical isochore of the CO 2 + n-decane mixture exhibits a renormalization of the critical behavior of C VX typical for mixtures. The values of the characteristic parameters (K 1 , K 2 ), temperatures (τ 1 , τ 2 ), and the characteristic density differences ( ρ 1 , ρ 2 ) were estimated for the CO 2 + n-decane mixture by using the critical-curve data and the theory of critical phenomena in 730 Polikhronidi, Batyrova, Abdulagatov, and Stepanov binary mixtures. The ranges of conditions were defined on the T-x plane for the critical isochore and the ρ-x plane for the critical isotherm, for which we observed renormalization of the critical behavior for the isochoric heat capacity.

“…In 1990, Laugier et al [26] reported (vapor + liquid) equilibrium data for the (carbon dioxide + tetradecane) system at three temperatures, (290, 295, and 300) K. Chou et al [27] measured the (vapor + liquid) compositions for the binary and ternary systems containing carbon dioxide, n-decane, tetralin at temperatures (344.3 and 377.6) K for pressures to near-critical pressure. Spee and Schneider [28] conducted experiments to obtain the isothermal pressure-composition diagram on the binary and ternary mixtures containing carbon dioxide, hexadecane, 1-dodecanol, 1,8-octanedlol, and dotriacontane at temperature 393.2 K and at pressures up to 100 MPa.…”
