To understand the role of caustic addition and its effect on the bitumen extraction process, a novel flow cell and a Denver Cell extraction unit were utilized. This allowed for the comparison of sodium hydroxide and ammonium hydroxides effect on real oil sands ores. Several ores (A1, C-ore,...

Properties of thin liquid films between two approaching droplets or between a droplet and a solid surface are critical for emulsion stability and for mineral flotation. If the thin liquid film is stable, no coalescence occurs, while an unstable film will lead to rupture and coalescence or the...

Interactions of finely dispersed abrasive particles in chemical mechanical planarization (CMP) slurries play a vital role in determining the polishing performance. In this study, coupled influence of hydrodynamic and colloidal interactions on the attachment of nanosized ceria (CeO2) particles to...

In previous studies, nontoxic and biodegradable ethylcellulose (EC) was shown to be capable of breaking water-in-diluted bitumen emulsions. Nevertheless, the demulsification mechanism of EC has not been correlated to its effect on the physical properties of stabilizing interfacial asphaltene...

The formation of stable water-in-oil emulsions during oil sands extraction process causes a number of operational issues, such as equipment corrosion, storage and transportation problems. One common method for emulsion breakup in industry is to use chemical demulsifiers. The chemical demulsifiers...

The emulsions, either oil-in-water (O/W) or water-in-oil (W/O) emulsions, are inevitably formed during the industrial production processes and the daily household activities. The O/W emulsions such as crude oil-in-water emulsions or oily wastewaters generated from the industrial fields, oil...
