“…The study reveals that gas velocity significantly impacts bypass pig speed, followed by bypass area and friction force. Wu et al [20] conducted an experimental study on the pigging process at natural gas pipeline aerial crossings, including simulation and dynamic response. Due to the lack of empirical research, the main problem is the fluid-structure coupling vibration caused by two phases for more complex structures.…”

The initial running speed of the pig during gas–liquid two-phase pipeline pigging can significantly influence the velocities of both gas and liquid phases within the pipeline. However, due to the complexity and limited understanding of these velocity variations, developing an effective operational plan for pigging becomes challenging. To enhance pigging efficiency and effectively seal the pig, it is crucial to monitor the velocity variations in the gas–liquid phase within the pipeline. In this study, an experimental platform was established to facilitate precise observation of these variations. Particle image velocimetry (PIV) technology was employed for a comprehensive understanding of gas–liquid two-phase velocities during pig operation in the pipeline. The experimental results demonstrated that increasing both the velocity and the initial liquid level height of the pig resulted in a corresponding augmentation of velocity fluctuation range. Specifically, at a holdup rate of 30%, there was a 10% reduction in the maximum liquid-phase velocity, while at a holdup rate of 25%, this reduction amounted to 16% compared to the pigging velocity.

“…As a mixture containing complex substances, raw natural gas contains several impurities that can increase the gas transmission resistance, which affects its value and prospect in commercial application. [1][2][3] To meet the environmental standards and caloric value specications of renewable energy supplements, the undesirable constituents, such as CO 2 , must be removed before natural gas is delivered to the pipeline network. 4 To achieve this target, natural gas purication needs to be conducted before its commercial application, which involves the CO 2 /CH 4 gas mixture separation processes.…”
