Carbon dioxide (CO2) ocean sequestration technologies, such as dissolution into seawater, are important to promote protection of the global environment. In this study, the solution process of CO2gas in seawater and pure water was experimentally studied under various pressures and temperatures to evaluate the solubilities of CO2in seawater. The solubilities of CO2in seawater and pure water were measured by the change in pressure due to absorption at pressures up to 1500 kPa and temperatures ranging from 20°C to 60°C. We found that the solubilities of CO2were between 0.27×10-3and 5.45×10-3in seawater, and between 0.26×10-3and 0.6×10-3in pure water near atmospheric pressure. They increase with an increase in pressure, but decrease with an increase in temperature. The Henry's law constant of CO2was about 200 MPa at a temperature of 20°C in seawater under 500 kPa, and increased with an increase in temperature. The solubility of CO2in seawater was lower than that in pure water. We obtained empiri-cal correlations for solubilities of CO2in seawater and pure water at various temperatures under atmospheric pressure, based on the experimental data.
