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.

“…The VLE of the binary system of CO 2 + N 2 has been extensively studies in the literature (Arai et al, 1971;Brown et al, 1989a,b;Ke et al, 2004a;Muirbrook and Prausnitz, 1965;Somait and Kidnay, 1978;Xu et al, 1992;Yorizane et al, 1970;Yorizane et al, 1985;Yucelen and Kidnay, 1999;Zenner and Dana, 1963), whereas only a few studies have been published for the CO 2 + H 2 system (Bezanehtak et al, 2002;Kaminishi and Torimumi, 1966;Spano et al, 1968;Tsang and Streett, 1981;Yorizane et al, 1970). No experimental VLE studies can be found for the ternary mixtures of CO 2 + N 2 + H 2 at high pressures.…”

Gas adsorption rates of H 2 , CO 2 , and H 2 -CO 2 gas mixture (H 2 /CO 2 5 3.4) with tetra-n-butyl ammonium salt (bromide, chloride, and fluoride) semi-clathrate hydrate particles were measured at 269 K to assess their properties for gas separation. Equilibrium gas occupancies in the S-cages of the particles were in order of (high to low) for hexagonal structure-I, tetragonal structure-I, and superlattice of cubic structure-I structures with the maximum fractional occupancy by CO 2 being about 40%. The CO 2 diffusion rate depended on the anion size of the salt, which is attributed to distortion of the S-cage that is close to the molecular size of CO 2 . Simulations of semi-clathrate hydrate particles with theory showed that H 2 /CO 2 selectivities could be as high as 36 (3.0 mol% TBAF) and that selectivities for an ideal membrane (3.3 mol% TBAF) could be >100 (269 K, 0.3-4.5 MPa). Semi-clathrate hydrates have wide application as separation media for gas mixtures.
