“…16 Finally, Zambrano et al, reported densities at pressures up to 100 MPa, for a temperature domain of 283.15−393.15 K, at four CO 2 compositions from 0.3011 to 0.9517. 17 Equally important, the CO 2 + naphthalene binary system has been extensively studied regarding phase behavior, whereas a limited number of volumetric experimental data are available, focused on mixture saturation properties of the mixture. 18,19 Kalaga et al, studied the volumetric behavior CO 2 + naphthalene binary system for a molar fraction of naphthalene varying from 0.0083 to 0.0248, at two temperatures (308.15 and 318.15 K), and pressure up to 20 MPa.…”

Densities of the carbon dioxide + n-decane binary system and carbon dioxide + n-decane + naphthalene ternary system have been measured up to 130 and 100 MPa, respectively, by using a vibrating tube densitometer. The measurements covered the molar compositions of CO2 of 0.1182, 0.3050, 0.6271, and 0.9539 for the first system, at temperatures from 318.15 to 358.15 K. While for the ternary mixtures, the measurements were performed for four compositions: high alkane, high aromatic, high CO2, and one equimolar content, at a temperature range of 328.15–423.15 K. From these data, excess molar volumes were calculated for both systems, showing positive values at lower temperatures and higher pressures for the binary mixtures, while negative values were observed for the ternary mixtures over the entire composition range. For both systems, the density was correlated by using a modified Tammann–Tait equation, as a function of temperature and pressure, presenting a maximum deviation of 0.63 and 1.72% for the binary and ternary systems, respectively. Additionally, isothermal compressibility and isobaric thermal expansivity were calculated from the experimental density data. It was observed that higher compressibility values were found at lower pressures and at higher CO2 content for both binary and ternary systems. Rich aromatic systems are less compressible when compared to rich CO2 systems. Regarding isobaric thermal expansivity, temperature dependence could be neglected for all binary mixtures. However, for the ternary mixtures, this dependence was strongly related to mixture composition.

“… The calculated dynamic mole fraction of CO 2 ( x CO2 ) and mole fraction of n-decane ( x HC ) was further be used to obtain the density of the P d consisting of a binary mixture ( ρ Pd ) at every experimental time step by Eq. (5) [ [15] , [16] , [17] ].

where ρ CO2 and ρ HC are the densities of CO 2 and hydrocarbon in the drop, respectively (obtained from NIST webbook [ 11 ]).…”

“…Zhang et al 10 studied the volumetric behavior of this mixture at four carbon dioxide mole fractions: 0.2497, 0.5094, 0.7576, and 0.8610, at temperatures ranging from (313.55 to 353.55) K, and pressure up to 18 MPa. Moreover, Zambrano et al 11 also measured the experimental density data for the CO 2 + ndodecane binary mixture at a temperature range of (283.15− 393.15) K and p = (10−100) MPa. Recently, Bazile et al 12 measured densities of the CO 2 + n-dodecane mixture with CO 2 molar percentage ranging from 20 to 85% at pressures from (10 to 70) MPa and at two temperatures around the critical temperature of carbon dioxide (303 and 313) K. To the best of our knowledge, there are no available density data for the CO 2 + n-heptane + n-dodecane ternary system.…”

Density measurements of the n-heptane + n-dodecane binary mixture were performed with a vibrating tube densitometer in the temperature range of (293.15 to 363.15) K and pressure up to 70 MPa at six different n-heptane mole fractions: x 1 = 0, 0.1999, 0.3991, 0.5999, 0.7998, and 1. Densities of the CO2 + n-heptane + n-dodecane ternary mixtures were also measured at the same temperature and pressure ranges for two different isopleths: CO2 (0.4904) + n-heptane (0.2548) + n-dodecane (0.2548), and CO2 (0.7425) + n-heptane (0.1288) + n-dodecane (0.1288). The obtained experimental data were correlated by a polynomial model and by a Tait-based equation. Density values for pure n-heptane and n-dodecane were found to be in agreement with literature data within approximately 0.3%. The isothermal compressibility and thermal expansion values of these mixtures were obtained by differentiation from the models as a function of pressure and temperature. Analysis of these properties pointed out that the polynomial model provided more accurate results related to derived properties. The excess volume of the mixtures was also determined. In general, they are negative, but they become positive for binary mixtures in the heptane-rich region as well as at higher pressures for ternary mixtures.
