“…Recently, much attention has been given to studies of the thermodynamic properties, such as vapour-liquid equilibrium (VLE) and density of CO2 mixtures with impurities. A number of research groups have studied some of these key binaries, such as CO2/N2 (Fandino et al, 2015;Mantovani et al, 2012;Tenorio et al, 2015;Westman et al, 2016b), CO2/Ar (Coquelet et al, 2008;Köpke and Eggers, 2007;Mantovani et al, 2012;Yang et al, 2015a), CO2/H2 (Cipollina et al, 2007;Fandino et al, 2015;Sanchez-Vicente et al, 2013;Tenorio et al, 2015), CO2/O2 (Mantovani et al, 2012;Westman et al, 2016a), CO2/SO2 (Coquelet et al, 2014;Köpke and Eggers, 2007), CO2/CO (Cipollina et al, 2007), CO2/H2S (Chapoy et al, 2013a) and CO2/H2O (Hou et al, 2013;Valtz et al, 2004), which either focused on the binaries with an insufficient amount of data under the conditions relevant to CCS or aimed at reducing experimental uncertainties. A comprehensive data survey of the available thermodynamic properties of binary systems with CO2 can be found in the monograph by Kunz et al (2007) and in the recent reviews by Munkejord et al (2016) and Li.…”

The p-T phase diagrams of two ternary systems (CO2 + Ar + N2 and CO2 + Ar + H2) have been measured at temperatures between 268 and 303 K using a fibre-optic phase equilibrium analyser. CO2, which is the major component, has a mole fraction ranging from 0.90 to 0.98 in both systems. The molar ratio of the two minor components is Ar:N2 = 1:1 and Ar:H2 = 2:3, respectively for the two ternary systems. In addition, the density of a ternary mixture with xAr =

“…However, to the best of our knowledge, the situation of accurate vapor-phase ( p , ρ, T, x ) data for binary carbon dioxide-rich mixtures is rather poor. In our present research project, we investigated the binary system (carbon dioxide + argon); the available experimental ( p , ρ, T, x ) data for this particular system were summarized by Yang et al No data are available with compositions of about 0.95 mole fraction carbon dioxide. To fill this data gap, accurate density measurements at temperatures T = (273.15, 283.15, 293.15, 308.15, and 323.15) K with pressures up to dew-point pressure or p = 9.0 MPa, whichever is lower, were carried out on a (0.05049 argon + 0.94951 carbon dioxide) mixture utilizing a two-sinker magnetic suspension densimeter.…”

Accurate density measurements on a binary (argon + carbon dioxide) mixture were carried out at temperatures T = (273.15, 283.15, 293.15, 308.15, and 323.15) K with pressures up to the dew-point pressure or 9.0 MPa, whichever was lower. A two-sinker magnetic suspension densimeter was utilized for the measurements. The composition of the gravimetrically prepared mixture was 0.94951 mole fraction carbon dioxide. Taking the measurement uncertainties in temperature, pressure, density, and composition into account, the relative combined expanded uncertainty (k = 2) in density was estimated to be less or equal 0.043% of the measured density value. Relative deviations of the new experimental data from the GERG-2008 equation of state (EOS) and from the EOS-CG (a recently developed multiparameter EOS optimized for combustion gases) were within 0.95% and 0.18%, respectively. Third-order virial equations were fitted to the new experimental data. The correlated molar masses at different isotherms agreed with the gravimetrically determined one within 0.02%. Values and uncertainties of the second and third virial coefficients and the second interaction virial coefficient for the binary mixture were determined.

“…For this particular binary mixture system, an obvious lack of accurate experimental data was observed. In this context, the available experimental ( p , ρ, T , x ) data before the year 2016 were summarized by Yang et al To fill the data gap for the binary (argon + carbon dioxide) system, and for the sake of improving the performance of mixture models, the ( p , ρ, T , x ) behavior of binary (argon + carbon dioxide) mixtures with 0.50000, 0.49975, and 0.75093 mole fraction carbon dioxide was investigated. We used the same two-sinker magnetic suspension densimeter as in our previous work within the same project.…”

A two-sinker magnetic suspension densimeter was used to carry out accurate density measurements on binary mixtures (argon + carbon dioxide) with carbon dioxide mole fractions of 0.50000, 0.49975, and 0.75093. The measurements cover a temperature range from T = (273.15 to 323.15) K with pressures up to 9.1 MPa or the dew-point pressure, whichever was lower. The mixtures were prepared gravimetrically. With all measurement uncertainties in temperature, pressure, density, and composition taken into account, the relative combined expanded uncertainty (k = 2) in density was estimated to be less or equal to 0.033%. Relative deviations of the experimental densities from the GERG-2008 equation of state were within 0.31% for the mixtures with 0.50000 and 0.49975 mole fraction carbon dioxide and up to 1.90% for the mixture with 0.75093 mole fraction carbon dioxide. In contrast, the relative deviations from a recently developed multiparameter equation of state (EOS) optimized for combustion gases (EOS-CG) were less than 0.30% for the three mixtures under study. Third-order virial equations were fitted to the measured density values. The correlated molar masses at different temperatures agreed within less than 0.01% with the molar masses determined from the gravimetric mixture preparation. Values and uncertainties of the second and third virial coefficients as well as of the second interaction virial coefficient were calculated.
