An Electrochemical Impedance Spectroscopic Diagnostic Device for Characterization of Liquid-Liquid Systems and Phase Separation Detection in Emulsions
DownloadFall 2013
Rapid characterization of complex fluids, especially sensing emulsion stability, is crucial for many industrial applications, ranging from pharmaceutical industry to petroleum production. Electrochemical impedance spectroscopy (EIS) is a powerful tool for electrical characterization of such...

Fall 2014
The formation of stable water-in-oil emulsions during bitumen extraction poses problems for water separation from diluted bitumen, which leads to equipment corrosion and catalyst fouling in downstream operations. Demulsifiers are used to break the stable emulsions and assist the separation of...

Electrocoalescence of Water Droplets in Oil Emulsions: Effect of Electric Fields, Surfactants, and Chemical Demulsifiers
DownloadSpring 2019
Stabilization of water-in-oil droplets during bitumen extraction and refining process poses a major challenge in the oil sands industry. These crude oil emulsions are stabilized by rigid films at water droplet-oil interfaces. The salty water remaining in oil causes equipment corrosion, catalyst...

Emulsification and Emulsion Flow in Thermal Recovery Operations with a Focus on SAGD Operations A Critical Review
Download2019-11-11
Steam assisted gravity drainage (SAGD) is a thermal hydrocarbon recovery method by which extra-heavy oil is produced through steam injection and bitumen heating. The presence of emulsions in the produced fluid has been detected from the very beginning of SAGD deployment. However, this...
