Demulsification Mechanism of Asphaltene Model Compounds- or Bitumen- Stabilized Emulsions by EO-PO Copolymers
DownloadFall 2019
The formation of stable water-in-oil (W/O) emulsions in the oil sands industry is highly undesirable because it poses great threats to the downstream operations, such as downstream upgrader corrosion, catalyst fouling, increased pumping cost, etc. To break the stable emulsions and to assist the...

Probing the Molecular Interactions of an Asphaltene Model Compound in Organic Solvents and Aqueous Solutions by Surface Forces Apparatus (SFA)
DownloadSpring 2012
A fundamental understanding of the molecular interactions between asphaltene molecules in bulk and at oil-water interface is of great value in crude oil production. Yet, the chemical composition and molecular structures of asphaltenes are not fully understood. The objective of this study is to...
