A high temperature equation of state for the H2O-CaCl2 and H2O-MgCl2 systems
An equation of state (EOS) is developed for salt-water systems in the high temperature range. As an example of the applications, this EOS is parameterized for the calculation of density, immiscibility, and the compositions of coexisting phases in the CaCl2-H2O and MgCl2-H2O systems from 523 to 973 K and from saturation pressure to 1500 bar. All available volumetric and phase equilibrium measure...
متن کاملExtraction of Thermodynamic Data from Ternary Diffusion Coefficients of Lysozyme Chloride in Water and Aqueous Na2SO4
This paper presents, for ternary lysozyme-Na2SO4-water system, the thermodynamic data extracted from the measured values of four ternary diffusion coefficients and the Onsager reciprocal relations. The calculation for derivatives of solute chemical potentials with respect to solute molar concentrations was made using the method presented in [1]. This method is applicable to systems in which the...
متن کاملSTUDY OF TWO STRUCTURAL POLYMORPHS OF MgSO4·H2O BY RAMAN, IR, XRD, AND HUMIDITY BUFFER EXPERIMENTS – IMPLICATION FOR MARTIAN KIESERITE
Mystery of martian kieserite: Kieserite (MgSO4· H2O) was identified on Mars based on NIR reflectance spectra obtained by OMEGA instrument on the Mars Express and CRISM instrument on the MRO [1, 2, 3]. Nevertheless, the pathway of forming kieserite on Mars is quite perplexing. Laboratory experiments [4, 5, 6, 7] have demonstrated that if epsomite (MgSO4. 7H2O) or hexahydrite (MgSO4.6H2O) precipi...
متن کاملH2O diffusion in dacitic melts
We report the first experimental study of the diffusion of H2O in dacitic melts. Dehydration experiments were conducted at 551–637 8C and 1–1450 bars for samples with ~0.8 to ~2.5 wt.% total dissolved H2O. The H2O diffusivity is proportional to total H2O contents at V0.8 wt.%, but increases exponentially with total H2O at higher H2O contents. The diffusivity of the total dissolved H2O (in Am /s...
متن کاملH2O diffusion in dacitic and andesitic melts
The diffusion of water in dacitic and andesitic melts was investigated at temperatures of 1458 to 1858 K and pressures between 0.5 and 1.5 GPa using the diffusion couple technique. Pairs of nominally dry glasses and hydrous glasses containing between 1.5 and 6.3 wt.% dissolved H2O were heated for 60 to 480 s in a piston cylinder apparatus. Concentration profiles of hydrous species (OH groups an...
