“…It presents two dispersion mechanisms in crushed coal scenario. One is the gaseous dispersion with a faster rate due to lower density and viscosity, 36 and thus forming an initial vertical dispersion region in 30 seconds 9,14 . Another is the dispersion of gas‐solid co‐existing phase, which will lead to a significant mass transport of CO 2 in crushed coal by forced convection 26 .…”

“…In carbon capture and storage process, as an economical media for transporting, many studies concentrated on the dispersion characteristics when accidental releases of LCO 2 from high-pressure pipelines or vessels occur in the atmospheric. [11][12][13] Gant et al 14 conducted experiments to study CO 2 dispersion behaviors by testing the variations of temperature and concentration. It is found that significant cooling effect caused by phase transition occurred near the nozzle and a certain amount of dry ice is also observed.…”

Summary The safety issues are a major restriction on coal mining and growing efforts are being made in the search for solutions that will guarantee sustainable use of energy resources. Liquid carbon dioxide is attracting particular interest of coal fire‐fighting due to the promising efficiency of cooling and asphyxia. Our objective is to develop a valid model to simulate the dispersion and thermal behaviors of liquid carbon dioxide under crushed coal condition and assessment of liquid carbon dioxide injection for coal fire‐fighting. For this purpose, a numerical approach which requires an accurate state equation for calculating physical parameters of carbon dioxide, also accounts for appropriate description of energy transformation during the injection is presented. The validation of such a model against three experimental tests on temperature variation is proposed, and the model has proved capable of accurately predicting the heat and mass transfer process when liquid carbon dioxide is injected into crushed coal. Furthermore, the impact of nozzle diameter on the dispersion and thermal behaviors of liquid carbon dioxide is extensively investigated.

“…INERIS [14,15] built a 2 m 3 spherical vessel to measure temperatures and gas concentrations in the dispersion region during CO 2 releases. An important observation from this work was that significant solids are generated within the near-field of dense phase releases, despite the inventory initially containing no dry ice itself.…”

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.

“…Many experimental studies have been conducted to establish a clear understanding of the hazards associated with the failure of CO 2 pipelines. As part of the CO 2 PipeHaz project, INERIS [13][14][15] built a 2 m 3 spherical vessel connected to a 9 m long pipe with an inner diameter of 50 mm. This apparatus was used to measure temperatures and gas concentrations in the dispersion region during outflow from the pipe in order to guide large scale experimental CO 2 release studies.…”

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.
