The Thermodynamics of Supercritical Fluid Systems

Hydrothermal Solutions

“…PVT data for CO 2 were measured by Juza et al [85) to 4 kbar and 475°C and by Shmonov and Shmulovich [86) to 10 kbar and 1OO0°C. The latter authors also calculated fugacity coefficients from their PVT data for the same pressure and temperature ranges [87). Equations of state for carbon dioxide based on modifications of the Redlich-Kwong equation of state were developed by Bottinga and Richet [88) and by Kerrick and Jacobs [89].…”

“…PVTx data of homogeneous mixtures of water and carbon dioxide were determined by Franck and Todheide [91], Greenwood [92,93], Gehrig [94], and Shmulovich et al [95] up to 600°C and 5 kbar. Activity coefficients for water and carbon dioxide were calculated from the different data sets.…”

pVTx Properties of Hydrothermal Systems

“…Errors ranging between ±0.2% and ±0.7% were reported by some authors (Shmulovich et al, 1979) at 450-500 MPa using similar apparatuses.…”

Fluids in geological processes

“…Numbers indicate studies carried out in the past 10-12 years (for earlier reviews, refer to: Zharikov et al, 1973b;Zharikov, 1976b;Fyfe et al, 1978;Shmulovich et al, 1982;Carmichael and Eugster, 1987). It can be seen that the systems H2O-C02, H20-chloride, H2O-C02-NaCI have received extensive study over wide temperature-pressure ranges.…”
