Water Solubility in High-Pressure CO2 for Carbon Capture Applications

A synthetic-dynamic method using ATR-FTIR spectroscopy measures water solubility in high-pressure CO2. The dataset provides dew point data at three pressures (4.05, 5.05, and 6.03 MPa) across water mole fractions from 0.01 to 0.04. This research, funded by UKCCSRC Grant UKCCSRC-C2-185, addresses a literature gap critical for Carbon Capture and Storage pipeline integrity.

Use Cases

• Model phase behavior of CO2 + H2O mixtures using dew point data at specified pressures and mole fractions.
• Analyze the relationship between pressure and water solubility for pipeline corrosion risk assessment in CCS.
• Validate thermodynamic models against experimental dew point measurements across the 0.01 to 0.04 mole fraction range.

Strengths

• Data addresses a known literature gap for pressures between 4.05 and 6.03 MPa.
• Experimental conditions are precisely defined with three distinct pressure levels and a mole fraction range.

Limitations

• The dataset scope is limited to three specific pressures and a narrow mole fraction range (0.01-0.04).
• Sample data and structural details like row and column counts are unavailable for assessment.
