“…The outflow near-field is also instrumented with pressure transducers and thermocouples (up to 50 cm from the orifice) to investigate the expansion zone. The measurement of the mass flow-rate is of great importance for the validation exercise of the models (Martynov et al, 2013). To do this, electronic measuring load cells were installed at six locations between the top of the supporting masts (in blue on Figure 8) and the bottom of the pipe.…”

This paper provides an overview of the aims, objectives and the main findings of the CO 2 QUEST FP7 collaborative project, funded by the European Commission designed to address the fundamentally important and urgent issues regarding the impact of the typical impurities in CO 2 streams captured from fossil fuel power plants and other CO 2 intensive industries on its safe and economic pipeline transportation and storage. The main features and results recorded from some of the unique test facilities constructed as part of the project are presented. These include an extensively instrumented realistic-scale test pipeline for conducting pipeline rupture and dispersion tests in China, an injection test facility in France to study the mobility of trace metallic elements contained in a CO 2 stream following injection near a shallow-water qualifier and fluid/rock interactions and well integrity experiments conducted using a fully instrumented deep-well CO 2 /impurities injection test facility in Israel. The above, along with the various unique mathematical models developed, provide the fundamentally important tools needed to define impurity tolerance levels, mixing protocols and control measures for pipeline networks and storage infrastructure, thus contributing to the development of relevant standards for the safe design and economic operation of CCS.Dedication: This paper is dedicated to the memory of our friend and colleague, Dr. Robert M. Woolley, who made a significant input to the CO 2 QUEST project and whose expertise, commitment and support inspired many of those around him.

“…Central to the efficient utilization of LCO 2 injection for cooling coal is the accurate prediction of thermodynamic phenomenon caused by phase transition in the event of unpressurized release. 15 Because of the high density, LCO 2 was always used as a transport medium during carbon capture and storage application. For the purpose of risk assessment, numerous studies focused on the phase transition and atmospheric dispersion behavior of LCO 2 after the rupture of the transporting pipeline.…”

Using liquid carbon dioxide (LCO2) as a medium for underground coal fires prevention and control, while reducing the emissions of CO2, is a promising option for CO2 utilization worldwide. However, the mechanism of LCO2 flow with phase transition on coal temperature is still not clear. In this work, an experimental system was designed and fabricated to investigate the phase transition behavior and temperature variation during injecting LCO2 into pulverized coal and the impact of mass flow rate, nozzle diameter, and injection pressure on cooling effect. The results indicate that when LCO2 was injected into the pulverized coal, the instantaneous phase change into solid and vapor occurred just after leaving the release port. An intensive heat transfer process occurred because of the throttling effect, flashing effect, and sublimation and thereby formed a cooling area (<−56.6°C), which was the main area of cooling effect and phase transition; as injection time increases, the range of this area increases in the form of logarithmic function. In addition, the cooling area exhibited a strong dependence on the injection conditions, and its correlation with mass flow rate, nozzle diameter, and injection pressure are identified as exponential, logarithmic, and linear relationship by dimensionless analysis, respectively. Meanwhile, an empirical formula was developed for calculating the cooling effect under various injection conditions. In summary, the experiments provided fundamental data and regime for predicting the effect of LCO2 injection on the temperature of pulverized coal, which can be used to guide the utilization of LCO2 for coal fires prevention. © 2020 Society of Chemical Industry and John Wiley & Sons, Ltd.

“…Fredenhagen and Eggers [8] considered the vessel blow-down model as a limiting, zerodimensional, version of the pipeline release model where the momentum of the fluid upstream of the release point is neglected. For experimental investigation of the flow properties of releasing from high-pressure CO 2 pipelines, Martynov et al [5] performed the experimental validation of a three-phase flow model for predicting the transient outflow following the failure of pressurised CO 2 pipelines and vessels. Han et al [9] investigated the flow properties in the jettisoning flow line of a liquid CO 2 carrier.…”

Transportation safety of supercritical CO 2 pipeline is a key aspect of carbon capture and storage (CCS). For reducing the high pressure in supercritical pipeline when accidental cases arise, man-made release will be applied using chocking process. The downstream parameters of chocking process can be predicted based on the adiabatic process assumption. In the critical chocking process, the critical velocity at outlet is sonic. A chocking pipe can be designed for buffering between different chocking orifices according to the length of turbulence area produced by jetting momentum. For the effect of noise hazard produced by large jetting velocity, a muffler can be applied at the outlet of final stage orifice to atmosphere. For the influence of impurities on the chocking process of anthropogenic CO 2 pipeline, the presence of SO 2 as an impurity is helpful for increasing the downstream temperatures through the chocking device to prevent the frozen hazard, whereas the presence of N 2 as an impurity indicates a lower downstream temperature. The higher initial temperature can prevent the dry ice formation at the outlet of vent pipe when the multistage chocking is applied.
