“…4(A) inset). The emulsion was stable without observable phase separation for at least 24 h. Such kinetic stability of the emulsion can be attributed to the presence of naturally occurring emulsifier such as asphaltenes, naphthenic acid, carboxylic acid, and other oil-soluble acids and bases in crude oil [65,66].…”

a b s t r a c tThe efforts of developing anti-oil-fouling membranes have so far been focusing on tailoring membrane surface wetting properties, whereas the impacts of surface charge are often eclipsed. In this study, we investigated the impacts of surface charge and wetting property on oil fouling kinetics in membrane distillation (MD). Two composite membranes with in-air hydrophilic and underwater oleophobic surfaces, one of positive charge and the other of negative charge, were fabricated by modifying a hydrophobic polyvinylidene fluoride (PVDF) membrane with hydrophilic polyelectrolytes with different charges. The modified composite membranes were compared with the reference PVDF membrane for their contact angles, adhesion force curves, and fouling kinetics in MD processes. It was found that the negatively charged composite membrane performed the best in mitigating fouling by the negatively charged oil emulsion, followed by the positively charged composite membrane, with the pristine PVDF membrane being the most susceptible to oil fouling in MD experiments. The results from underwater oil CA measurements and oil probe force spectroscopy corroborated the results in the fouling experiments. The impact of surface charges on oil-membrane interaction and associated mechanism were also discussed.

“…Hydrophilic particles stabilize O/W emulsions if they are small and their surfaces are not modified, but they stabilize W/O emulsions if dried and added to an asphaltenecontaining oleic phase [14]. Montmorillonite, kaolin and Fe 2 O 3 do stabilize W/O emulsions when predried.…”

Résumé -Propriétés des émulsions de pétrole brut et leurs applications au transport des bruts lourds -De nombreuses avancées ont été réalisées dans le domaine des émulsions ces dernières années.Le comportement des émulsions est en grande partie contrôlé par les propriétés des couches adsorbées qui protègent les surfaces entre l'huile et l'eau. La connaissance de la seule tension interfaciale n'est pas suffisante pour comprendre les propriétés des émulsions ; la rhéologie de surface joue un rôle important dans de nombreux phénomènes dynamiques. La complexité des émulsions pétrolières vient de la composition de l'huile en termes de molécules présentant un caractère tensioactif comme les acides gras de faible masse moléculaire, les acides naphténiques et les asphaltènes. Ces molécules peuvent interagir et se réorganiser aux interfaces huile/eau. Le caractère non linéaire prononcé de la rhéologie de surface obtenu avec des couches d'asphaltènes peut expliquer les différences de comportement entre les émulsions de tensioactif et les émulsions d'asphaltène. Cet article présente une revue des propriétés des émulsions pétrolières. L'application au transport d'hydrocarbures très visqueux sous forme d'émulsion aqueuse est ensuite considérée. Abstract -Crude Oil Emulsion Properties and their Application to Heavy Oil TransportationMany advances have been made in the field of emulsions in recent years. Emulsion behavior is largely controlled by the properties of the adsorbed layers that stabilize the oil-water surfaces. The knowledge of surface tension alone is not sufficient to understand emulsion properties, and surface rheology plays an important role in a variety of dynamic processes. The complexity of petroleum emulsions comes from the oil composition in terms of surface-active molecules contained in the crude
