Solubility of Liquid CO2 in Synthetic Sea Water at Temperatures from 278 K to 293 K and Pressures from 6.44 MPa to 29.49 MPa, and Densities of the Corresponding Aqueous Solutions

Measurements are reported on the solubility of liquid CO 2 in synthetic sea water at temperatures from 278 to 293 K and pressures from 6.44 to 29.49 MPa and on the corresponding densities of the CO 2 aqueous solutions. On the basis of the experimental results, expressions for the solubility of CO 2 in sea water and density of the corresponding CO 2 aqueous solution as functions of temperature, pressure, and salinity were obtained. The resultant equations well represented experimental data: the average differences are 3% for solubility and less than 0.05% for density.
