摘要：This short communication introduces a phase-boundary tracking method that is tailored to capture the vapor-liquid-aqueous/liquid-liquid-aqueous three-phase boundaries in both pressure-temperature and pressure-composition phase diagrams. This method is applied to several reservoir fluid mixtures that exhibit fourphase vapor-liquid-liquid-aqueous equilibria. Our findings reveal that the phase boundaries identified by this tracking method converge at the apex of the vapor-liquid-liquid-aqueous four-phase region. At this apex, the compositions of the vapor phase and the CO 2 -riched liquid phase become identical, indicating the pinching out of the four-phase region.
