Progresses in Fluid Inclusion Synthesis in Quartz
Geofluids, Volume 2022, Issue 1, 2022., 2022 High‐temperature and high‐pressure (HTHP) fluids are one of the most extensive participants in geological events. The representative in situ sampling of the HTHP fluids, which is an essential prerequisite for precisely characterizing the HTHP fluids (including compositional and volumetric properties), has been a vital challenge.

Geofluids, Volume 2021, Issue 1, 2021., 2021 A novel density model for computing quartz solubility in H2O‐CO2‐NaCl hydrothermal fluids applicable to wide ranges of temperature and pressure is proposed. Based on the models of Akinfiev and Diamond (2009) and Wei et al. (2012), the effective partial molar volume of water (VH2O∗) is replaced by the partial molar volume of water (V¯H2O) by ...

Isochoric PVTx Measurements for the Carbon Dioxide + 1,1-Difluoroethane Binary System [PDF]
Journal of Chemical & Engineering Data, 2007 PVTx measurements for carbon dioxide (CO2, R744) + 1,1-difluoroethane (CH3CHF2, R152a) for both the two-phase and the superheated vapor regions are presented. The measurements were taken with a constant volume apparatus at temperatures ranging from (223 to 343) K and pressures from (60 to 3890) kPa along eight isochores.

Analysis of PVTx measurements for binary mixtures of R115 and R114 [PDF]
International Journal of Thermophysics, 1990 We have made PVTξ measurements of R115 and R114 at temperatures from 296 to 443 K, pressures from 0.4 to 9.8 MPa, and densities from 153 to 1387 kg·m−3, for four compositions, namely, 25, 50, 75, and 100 wt% R115. The data were obtained along isochores.

PVTx Properties of a Two-phase CO2 Jet from Ruptured Pipeline
Energy Procedia, 2013 AbstractSpan and Wagner equation of state (SW EOS) have been used to investigate changes in the thermodynamic properties of CO2 during a depressurization process from a pipeline into marine environment. The process is assumed to be isenthalpic, as only the thermodynamic change at the moment of depressurization is considered.
