Current research indicates that the nanoscale confinement effect can reduce the interfacial tension between gas and liquid, thereby increasing the likelihood of miscibility (Sun and Li, 2021, Song et al., 2021). Several studies have been conducted to investigate the phase behavior of hydrocarbon...
