Abstract

The solubility of CO₂ in pure water was investigated under high-pressure conditions, from 7 to 12 MPa. Temperature varied between 2.5-20 °C. CO₂ clathrate hydrate formed at temperatures below approximately 10°C. Saturated concentrations of CO₂ were determined from expanding dissolved gas. The solubility in the presence of the hydrate decreased with decreasing temperature and with decreasing pressure, although some researchers reported it decreased with higher-pressure conditions at about 7°C. Many other researchers reported that the pressure conditions did not affect the solubility in the presence of the hydrate. Although this is mostly correct, we did confirm a small difference in solubility due to pressure conditions.
