Application and challenges of liquid CO2
Carbon Capture and Storage (CCS) and maritime transportation
Projects around the world involve the capture of CO2 from industrial sources, its liquefaction, and transportation via LCO2 carriers to an onshore receiving terminal. From there, the liquid CO2 is transferred through pipelines to a subsea geological storage site sometimes over more than 2,500 meters (8,200 feet) beneath the seabed for permanent sequestration.
The challenges of handling liquid CO2
Liquid CO2 streams often contain a wide range of unwanted components, making it a significant challenge to provide a complete analysis while maintaining cost-effectiveness. Handling LCO2 in industrial applications like for Carbon Capture and Storage (CCS) involves exposure to trace impurities that can cause equipment corrosion, leading to unplanned downtime, and costly repairs. Another challenge is achieving proper impurity analysis, which relies on obtaining verifiably accurate and representative samples, even in low-pressure scenarios.
Key challenges and common pitfalls with in LCO2
Impurities and corrosion: Corrosive compounds and accurate impurity analysis in cryogenic conditions.
Reducing costs: Complete analysis while maintaining cost-effectiveness.
Accurate and representative samples: even in low-pressure scenarios.
Solutions for liquid CO2
Reliable analytical systems are essential for applications such as carbon capture and storage (CCS), maritime transport, and small-scale biogas plants. These systems should provide fast, high-resolution analysis of various CO2 impurities, ensuring reliable corrosion control and precise monitoring of critical components across different industrial processes.
Reliable liquid CO2 sampling in low-pressure conditions
The cryogenic sampling process begins with specialized probes designed to handle liquid CO2 sampling at pressures as low as 0.5 barg. This ensures accurate and representative samples even in low-pressure scenarios, making it suitable for applications such as ship-to-ship transfers, storage facilities, and truck loading operations.
Achieving cost-efficiency through analyzer technologies
Gas analyzers should be selected for comprehensive measurement capabilities for liquid CO2 streams. Technologies such as FTIR, Gas Chromatography, XRF, and electrochemical sensors enable detection of various impurities, including sulfur, oxygen, mercury, and hydrocarbons. A combination of the above technologies is needed for reliable impurity analysis, and in turn helps to manage corrosion risks to maintain process integrity.

Frequently asked questions about liquid CO2
Carbon capture is the process of capturing CO2 emissions from industrial processes, power plants, or directly from the atmosphere to prevent it from entering the atmosphere. This captured CO2 can then be stored underground in geological formations (carbon storage) or utilized in various applications (carbon utilization). Carbon capture is a key technology for reducing greenhouse gas emissions and combating climate change.
CO2 cannot exist as a liquid under normal atmospheric pressure because it transitions directly from a solid (dry ice) to a gas in a process called sublimation at standard atmospheric pressure. To form liquid CO2, it must be pressurized above 5.1 atmospheres (its triple point pressure) and kept at temperatures between -56.6°C and 31°C. These conditions are necessary to overcome the physical limitations of CO2’s phase behavior.
Long-term liability is a concern for carbon capture because stored CO2 must remain securely sequestered underground indefinitely to prevent it from leaking back into the atmosphere. Managing risks like containment failure, induced seismicity, or environmental damage requires robust monitoring, maintenance, and regulatory frameworks. Additionally, liability for future issues can create financial and legal challenges, discouraging investment and complicating the development of large-scale carbon capture projects.
