The formation of stable water-in-petroleum emulsions is it costly challenge when transporting, processing, and refining heavy crude oil and bitumen. The stability of these emulsions is attributed to interfacial films with well-documented viscoelastic properties that are known to vary with concentration, solvent quality, and asphaltene chemistry. In this Study, we explore the impact of aqueous phase pH and salinity on the transient interfacial rheological properties of asphaltenic films. Using two chemically unique asphaltenes, interfacial shear rheology revealed an apparent salt-induced retardation of the interfacial consolidation processes that ultimately engender elasticity to the film. For Hondo asphaltenes at pH 7, it linear dependence of this retardation on the Debye parameter (kappa) suggested that shielding of electrostatic attraction was responsible. Further investigation with dynamic oscillating droll tensiometry at pH 3, 7, and 10 illustrated that intralayer repulsive and attractive electrostatic interactions call significantly influence the evolution of the interfacial structure. More specifically, the transient tension and dilatational modulus profiles indicated several interfacial processes were affected by the addition of salt, including (i) interfacial activity and the extent of adsorption, (ii) interfacial rearrangement and consolidation, and (iii) interfacial transport or displacement or both. Furthermore, the observed asphaltene interfacial behavior was consistent with those published for interfacial structure-forming amphoteric proteins, such as lysozyme and beta-casein.
