Measurement and correlation of solubility of water in carbon dioxide-rich phase

The solubility of water in carbon dioxide-rich phase was measured over temperature range of 283.2–312.0 K and pressure of 8.1, 10.1 and 20.1 MPa. An indirect method was used to determine the solubility of water at given pressure and temperature. Measured experimental data were compared with literature data at similar conditions and correlated using Cubic Plus Association (CPA) equation of state which takes into account of association of water molecules and solvation between water and carbon dioxide.

► The solubility of water in carbon dioxide-rich phase was measured by an indirect method. ► Measured data were correlated by a CPA EoS Model. ► The measured data and optimum values of binary parameters are reported.
