This report provides a non-confidential summary of FEnEx CRC research project Low Pressure, Low Temperature Liquified CO2 Transportation Technology for Carbon Capture, Utilisation and Sequestration Demonstrations: Phase 1.
The CCUS industry is considering transport of liquid CO2 (LCO2) at novel low pressure (LP) conditions of around 7 bar. This low storage pressure permits larger quantities of LCO2 to be shipped compared to the medium pressure (MP) standard currently used for LCO2 shipping.
Because LP conditions have been put forward as a regime for LCO2 storage and transport, technical issues resulting from this shift to LP conditions need to be identified.
The Phase 1 project used laboratory experiments and dynamic simulations to investigate three technical areas of importance to LP LCO2 storage and transport:
- Accuracies of equations of state (EoS) for predicting vapour and liquid compositions for CCS-grade LP LCO2 particularly, LCO2 with light-end impurities (N2, CH4, H2, Ar).
- LCO2 solidification resulting from the small margin between LP conditions and CO2 triple point.
- Boil-off gas (BoG) rates and compositions for LP LCO2 with light-end impurities.
