“…At temperatures above 275 K the data of Bezanehtak et al [7] follow those Tsang and Street [6], while the data of Spano et al [4] and Kaminishi and Toriumi [3] agree with our results. As noted above, the vapor phase data are generally more scattered and this is especially evident at higher temperatures.…”

“…In comparison with the literature [3][4][5][6][7], there is generally good agreement at low temperatures in the liquid phase (see Figs 9a and 9c) with the exception of the results of Tsang and Streett [6] which deviate systematically from the other data in both phases. At temperatures above 275 K the data of Bezanehtak et al [7] follow those Tsang and Street [6], while the data of Spano et al [4] and Kaminishi and Toriumi [3] agree with our results.…”

“…The VLE region in the (CO2 + H2) system is bounded at low pressures by the vaporpressure curve of CO2, at high temperatures and pressures by the critical locus of the binary system and at low temperatures and high-pressures by the solid-vapor-liquid three-phase line. Different parts of this region have been studied by several authors [3][4][5][6][7]. Kaminishi and Toriumi [3] appear to have been the first workers to study this system and their measurements were made along five isotherms at temperatures between (233.15 and 298.15) K with pressures up to 20 MPa.…”

Vapor-liquid equilibrium data are reported for the binary systems (CO2 + H2) and (CO2 + N2) at temperatures between (218.15 and 303.15) K at pressures ranging from the vapor pressure of CO2 to approximately 15 MPa. These data were measured in a new analytical apparatus which is described in detail. The results are supported by a rigorous assessment of uncertainties and careful validation measurements. The new data help to resolve discrepancies between previous studies, especially for the (CO2 + H2) system. Experimental measurements of the three-phase solid-liquid-vapor locus are also reported for both binary systems.The vapor-liquid equilibrium data are modelled with the Peng-Robinson (PR) equation of state with two binary interaction parameters: one, a linear function of inverse temperature, applied to the unlike term in the PR attractive-energy parameter; and the other, taken to be constant, applied to the unlike term in the PR co-volume parameter. This model is able to fit the experimental data in a satisfactory way except in the critical region. We also report alternative binary parameter sets optimized for improved performance at either temperatures below 243 K or temperatures above 273 K. A simple predictive model for the three-phase locus is also presented and compared with the experimental data.

“…9(a)). There is no good agreement among the three available data sources [31,44,59], except the data of Bezhanetak [59] and According to the origin, equations of state may be classified into several families. The van der Waals family of cubic equations and the family of extended virial equations are examples.…”

The technologies for CO 2 capture and storage (CCS) differ much in design, operation conditions, and the amount and nature of impurities in the captured CO 2 . The presence of impurities affects the thermophysical properties of CO 2 significantly. In particular, properties such as phase equilibrium behavior, density, viscosity, thermal conductivity, and diffusion coefficient are much affected. The development and technical breakthrough of new CCS technology rely on a deeper understanding of the thermophysical properties of CO 2 mixtures. In this chapter, the available experimental data and theoretical models about the thermodynamic and transport properties of mixtures at conditions relevant to CCS have been summarized. Knowledge gaps have been identified; in particular, more measurements are needed to close the experimental gaps. In addition, the impacts of impurities on operation of different CCS processes have been discussed, including CO 2 conditioning, compression, liquefaction, transport, and storage. Recommended levels of impurities from different sources have been reviewed and compared.
