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 CO2 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 CO2 aqueous solutions. On the basis of the experimental results, expressions for the solubility of CO2 in sea water and density of the corresponding CO2 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.
