“…Guo et al, and Cao et al 25,26 investigated the phase, pressure, temperature, and wall temperature responses of gas-phase and dense-phase CO 2 during instantaneous release under initial conditions with different vent orifices through an industrial-scale experimental pipeline with a length of 258 m. The Nusselt number was calculated, and the heat-transfer mechanism of the transient depressurization process in the CO 2 pipeline was analyzed for different initial conditions. Quinn et al 27 visualized the rapid decompression process of dense phase and supercritical CO 2 using conventional high-speed photographic and spectroscopic techniques. The study analyzes the pressure response during rapid decompression and discusses the properties of decompression waves, evaporation waves, and oscillatory phase transitions during medium expansion.…”

Pipelines transporting impure supercritical carbon dioxide in the carbon capture, utilization, and storage (CCUS) chain exhibit varying decompression characteristics due to engineered emissions or accidental leakage, resulting in diverse temperature drops and heat transfer mechanisms in the media and pipe walls. Therefore, studying heat transfer characteristics during slow and instantaneous decompression is crucial to investigating pipeline operational risks. In this work, supercritical CO2 pipeline valve release and rupture disc release experiments were performed with a 1.5% molar ratio of N2 content in an experimental pipeline (16 m long, 100 mm inner diameter). The evolution of the medium and pipe wall's physical properties was measured and discussed. Two methods of depressurization were employed to analyze the phase changes and heat transfer processes in the pipe. The instantaneous decompression process has a shorter decompression time and undergoes fluctuating and stable decompression stages. The slow decompression process has a slower temperature drop rate, but the wall during the process can reach a lower minimum temperature. Both release methods cause a larger temperature drop and Nusselt number at the bottom of the pipe wall due to evaporation heat transfer compared to the middle and top. The slow decompression process demonstrates a higher peak Nusselt number at the bottom, resulting in superior heat transfer efficiency compared to the instantaneous decompression process. © 2023 Society of Chemical Industry and John Wiley & Sons, Ltd.
