Surfactant demulsifiers

It is still unknown what the mechanism is behind the transition from rigid to flexible character of the layer on the water-oil interface mentioned above. There is a strong possibility that a phase transition takes place there, most likely of a type known for microemulsion systems. An attempt at getting some insight into the phase equilibria in the system of bitumen, diluent, water, and perhaps added surfactants (demulsifiers) will be the subject of our future studies.

EDLB, solubility, rate of diffusion into the interface, and effectiveness at destabilizing the interface [4,87], A wide range of properties and parameters are used to characterize surfactant demulsifiers and predict their performance, from physical properties to compositional and structural analyses [88,99-102], although in practice the degree of characterization needed to tailor a demulsifier based on first principles is prohibitive.

Chemical demulsification by adding surfactant demulsifiers is still one of the most frequently applied industrial method to break the crude oil emulsions (Sjdblom et al., 2001)-This process can be very difficult and non-efficient to demulsify W/O emulsions of heavy viscous crude oils, and it takes a long time.
