“…A typical highly under-expanded jet flow structure was observed near the orifice. DNV-GL [20] developed a 0.5 m 3 pressurized vessel equipped with an actuator valve to discharge liquid CO 2 . The measured CO 2 concentrations in the dispersion zone tended to increase continuously while saturated liquid was being discharged and then to drop with the transition to vapor outflow.…”

Pressurized pipelines represent a key way of transporting CO 2 from emitter to storage site. Leakage of CO 2 through a small puncture is the most common form of pipeline failure during normal operation; such failures could lead to fracture. The study of pipeline depressurization and dispersion behavior is of paramount importance for assessing the possibility of fracture propagation and the impact of CO 2 releases on the surrounding environment. A large-scale pipeline (258 m long, 233 mm i.d.) was constructed to study the flow characteristics and dispersion of gaseous, dense and supercritical phase CO 2 during vertical leakage through a 15 mm diameter orifice. The fluid pressures and temperatures in the pipeline were recorded to study the pressure response and phase transition inside the pipeline. Video cameras and CO 2 concentration sensors were used to monitor the formation of the visible cloud and the concentration distribution in the far-field. There was a "two cold, intermediate hot" phenomenon during the vertical leakage in the dense and supercritical release due to the dry ice particle accumulation near the orifice. The intersection of the jet flow and settling CO 2 mixture resulted in complex visible cloud forms in dense CO 2 release.

“…However, this structure disappeared as the orifice size increased. DNV-GL [18] investigated the discharge of liquid CO 2 from a 0.5 m 3 pressurized vessel equipped with an actuator valve. The results showed that the CO 2 concentrations near the orifice depend mainly on the jet shape rather than the mass flow rate.…”

The widespread implementation of Carbon Capture and Storage (CCS) in industry will require extensive long-distance CO 2 pipeline networks to integrate the component technologies. The potential for pipeline rupture and leakage, possibly resulting in catastrophic accidents, will inevitably increase as networks become more extensive. The study of near-field source terms and dispersion behavior after pipeline rupture is an essential foundation of CO 2 pipeline risk assessment and will provide effective technical support for the implementation of large-scale CCS projects and contribute to pipeline safety. In the CO 2 QUEST project under-expanded CO 2 jets, cloud dispersion characteristics and the formation of dry ice particles in the near field were investigated during releases from a 258 m long, fully instrumented pipeline. Experimental data including cloud temperature, CO 2 concentration and the visual evolution of the cloud (recorded on film), was gathered to investigate cloud behavior and to support future work in the field of CO 2 pipeline safety. Experiments included the release of gaseous and dense phase CO 2 through three orifice diameters: 15 mm, 50 mm and Full Bore Rupture (FBR). The lower limit of gaseous CO 2 concentration for adverse effects in humans is 5 % v/v. Safety distances from the release, based on this threshold concentration limit, are determined and reported for each experiment conducted.
