... inconsistencies, or required special laboratory experiments to characterize the fluid. The approach developed in this study uses a cubic equation of state to solve for vapor/liquid/liquid equilibrium (VLLE), where asphaltene is the denser liquid phase. Precipitation from the liquid mixture occurs as its...

...-Huggins theory. They describe asphaltene stability in terms of reversible solution equilibrium and are based on the vapour-liquid equilibrium (VLE) that models the properties of the liquid phase and then, the liquid-pseudo-liquid equilibrium is described assuming that asphaltene precipitation does...

The beginning of the increase in the slope of the curve indicates an increase of the asphaltene content on the liquid phase. As consequence, reservoir and facilities plugging may...
