Water Solubility in CO2+N2 Mixtures for CCS Pipeline Safety

UKCCSRC research data on water solubility in carbon dioxide and nitrogen mixtures, measured at 25 and 40°C and pressures between 8 and 18 MPa. The study was conducted by the British Geological Survey using FTIR spectroscopy to aid the safety of CO2 transport for carbon capture and storage. The paper associated with this data was published in 2015.

Use Cases

• Modeling water solubility in CO2 transport pipelines based on measured ternary mixture data.
• Calibrating thermodynamic models for CCS fluids based on temperature and density parameters.
• Assessing pipeline corrosion risk based on water concentration data in CO2+N2 mixtures.
• Evaluating FTIR spectroscopy as a monitoring technique for CCS pipeline safety.

Strengths

• Data includes specific experimental conditions: two temperatures (25 and 40°C) and a pressure range (8-18 MPa).
• Quantifies the effect of nitrogen, showing it lowers water concentration in CO2 by up to 42% for a given pressure.
• Provides a direct link to a peer-reviewed paper with a DOI (10.1016/j.ijggc.2015.02.002).

Limitations

• Row count and column-level documentation are unknown, which may limit suitability assessment.
• Data may reflect the specific experimental bias inherent to the laboratory study conditions.
