VTechWorks staff will be away for the Thanksgiving holiday beginning at noon on Wednesday, November 22, through Friday, November 24, and will not be replying to requests during this time. Thank you for your patience, and happy holidays!
Critical properties of the NaCI-H20 fluid system are of fundamental
interest to a variety of geochemical applications including fluid inclusion
studies, numerical modeling of hydrothermal systems, and development of
theoretical models for twoÂ·component fluid systems. Although many workers
have expressed interest in NaClÂ·H20 fluid critical properties, most studies
have been limited to small compositional ranges with little agreement among
data sets at higher salinities. Critical densities are recorded in only one of
these reports, and no studies have determined the locations of NaCl-H20
critical isochores (PT projections of critical densities). Furthermore, no
studies to date have determined critical properties of NaClÂ·H20 solutions in
excess of room temperature saturation (26.4 wt.% NaCl).
