PVTx measurements for H2O+D2O mixtures in the near-critical and supercritical regions

The Journal of Supercritical Fluids, 2003
Abstract The PVTx relationships of H 2 O+D 2 O mixtures were measured in the near-critical and supercritical regions. Measurements were made using a constant-volume piezometer immersed in a precision thermostat. The volume of the piezometer V PT was corrected for both temperature and pressure expansions.

Measurements of gas phase PVTx properties for the ternary HFC-161/125/32 system

Fluid Phase Equilibria, 2006
Abstract As one of the promising alternative refrigerants to replace HCFC-22, the gas phase PVTx properties of the ternary mixture HFC-161/125/32 have been studied. A total of 140 gas phase PVTx properties for the ternary system was obtained at nine different compositions by using the isochoric method.

Crystallization of mixed clathrate hydrates under equilibrium and non-equilibrium conditions : PVTx measurements and thermodynamic modeling

, 2018
Dans ce travail, afin d'étudier la formation à l’équilibre et hors équilibre des hydrates mixtes de gaz, deux procédures de formation, rapide et lente, ont été appliqué à des mélanges de CH4-C2H6-C3H8-nC4H10-CO2-N2.

Experimental Determination of PVTX Relations of Fluids in the Diamond-Anvil Cell

Mineralogical Magazine, 1994
PVTX relations of geological fluids are of primary importance to many geological applications. However, accurate experiments performed above 6 kbar and 800~ are scarce, and therefore, uncertainties arise when different versions of equation of state (EOS) are used to extrapolate.

Measurements of PVTx properties for the binary refrigerant HCFC 142b + HCFC 22 system

Journal of Chemical & Engineering Data, 1991
This paper reports PVTx properties for the HCFC 142b + HCFC 22 system in a wide range of temperatures from 297 to 443, of pressures from 0.5 to 10.0 MPa, and of densities from 72 to 1079 kg/m[sup 3]. For 4 compositions, i.e., 20, 40, 60, and 80 wt % HCFC 142b, 422 PVTx measurements have been made along 31 isochores. The uncertainties of the temperature,
