Asphaltene is a component of crude oil that has been linked to serious production and
transportation issues. It is a solid oil component with various shapes and molecular …

We review the existing literature on asphaltenes at various types of interfaces: oil–water, air–
water, gas–oil and solid–liquid, with more emphasis on the oil–water interfaces. We address …

Asphaltenes are the heaviest components in crude oil. It is generally believed that
asphaltenes adsorbed at oil/water interface can form a protective layer to stabilize the water …

Crude oils are complex mixtures of organic molecules, of which asphaltenes are the
heaviest component. Asphaltene precipitation and deposition have been recognized to be a …

In a refinery, undesired high levels of salt concentration in crude oils are reduced by the
contact of water with crude oils, where an emulsion is formed. Later, the separation of the …

Emulsions, microemulsions, and foams are dispersions of two immiscible fiuids stabilized by
surface-active species. Emulsions and microemulsions are dispersions usually made with …

The sorption and rheological properties of an acidic polyaromatic compound (C5PeC11),
which can be used to further our understanding of the behavior of asphaltenes, are …

Asphaltenes have been suggested to play an important role in the remarkable stability of
some water-in-crude oil emulsions, although the precise mechanisms by which they act are …

Asphaltenes are a solubility class of crude oils comprising polyaromatic and heterocyclic
molecules with different interfacial activities. The previously neglected effects of …

Unconventional heavy oil ores (UHO) have been considered an important part of petroleum
resources and an alternative source of chemicals and energy supply. Due to the …
