**4.2 Effect of temperature on CO2 solubility in brine**

CO2 solubility decreases with increasing temperature as shown in Figure 4. Experimental data relevant for CCS and simulated data are displayed. The computational data curve (open diamonds) was calculated with Duan et al. (2003+2006)'s solubility calculator setting the pressure to 10 MPa and salinity to 1 mole NaCl/kg.

Fig. 4. CO2 solubility versus temperature at high pressures. The substantially lower value measured by Rumpf et al. (1994) is caused by the high brine salinity (cp. section 4.3). Duan et al.'s (2003+2006) data is simulation data (open diamonds); the other points are experimentally measured values
