摘要：
Densities and solubilities for binary systems of carbon dioxide + water and carbon dioxide + Weyburn-formation brine were measured at a temperature of 59 degreesC and pressures up to 29 MPa. Density values were obtained for both the saturated and unsaturated aqueous carbon dioxide solutions at different pressures. A correlation in the literature was used to predict the solubility of carbon dioxide in the aqueous phase, and the results were compared with the measured data. The measured density of aqueous carbon dioxide solutions was correlated as a function of carbon dioxide concentration and pressure. A simple method for determining the density of aqueous carbon dioxide solutions was recommended.
