Phase behavior of binary mixture of asphaltene+solvent and ternary mixture of asphaltene+solvent+precipitant

Asphaltene precipitation is a perennial problem in producing and refining crude oils. To study asphaltene precipitation, it is useful to model the solubility of asphaltenes in petroleum fluids as a function of temperature and liquid-phase composition. In this work a polymer solution model is used for asphaltene precipitation in two cases. In the first case a binary mixture is considered which consists of asphaltene as a polymer component and...
