“…6 and 7). As evidenced by earlier investigations (Tödheide and Frank 1963;Takenouchi and Kennedy 1965;Gehrig et al 1986), the presence of dissolved salts significantly raises the critical line of the CO 2 -H 2 O mixture.…”

“…For many studies, the range of experimental conditions extends beyond the range listed here for the conditions of interest Table 3 Experimental studies used for the parameterization of activity coefficients for saline solutions Cramer (1982) 25-144 8-21 0.5-2 m NaCl Drummond (1981) 20-305 35-206 1-6 m NaCl Malinin and Kurovskaya (1975) 25-100 48 0.36-5.9 m NaCl Malinin and Savelyeva (1972) 20-100 48 0.44-6 m CaCl 2 Takenouchi and Kennedy (1965) 150-300 100-600 1.1-4.3 m NaCl Prutton and Savage (1945) 76-121 15-610 1.1-4 m CaCl 2 Markham and Kobe (1941) 24-40 1 1-4 m NaCl For many studies, the range of experimental conditions extends beyond the range listed here for the conditions of interest a Excluding points above 4 mol% CO 2 in the critical region fall within a narrow scatter of experimental data points, with a root mean square difference (RMSD 1 ) of about 7% (left side of Figs.1 and 2). Note that at 300 • C, the dew point data of Blencoe et al (2001) are well reproduced up to pressures of about 500 bar, above which the model reliability should be questioned as full miscibility is approached (according to Blencoe et al 2001, the critical line at 300 • C occurs at about 567 bar).…”

“…J. T. Nash's estimate (written commun., March 1980) of 2-10 mol percent (5-20 weight percent) C02 in fluids that were trapped in inclusions in the recrystallized (milky) quartz seems reasonable. According to Takenouchi and Kennedy (1965, fig. 2), in the temperature range of 270°-290°C and pressure range of 240-280 bars, at which the recrystallized quartz formed, 6 weight percent NaCl solution could contain a maximum of 6-7 weight percent CO2.…”

“…The calculation results presented on Figure 6 can be favourably compared to the measurements of Takenouchi and Kennedy (1964). On the basis of the experimental data from Malinin and Kurovskaya (1975), we carried out other CO 2 solubility calculations in 0.44 M and 0.88 M CaCl 2 solutions for moderate temperatures (25 to 75°C).…”
