A Study on the Effect of Temperature and Pressure on the Removal of Cyclohexane from Non-Aqueous Extraction Gangue
DownloadSpring 2015
Solvent based extraction has the potential to supplant the current hot water based extraction process as the industry standard method for recovering bitumen from mined oil sand. It has the potential for higher bitumen recovery that is less sensitive to the grade of oil sand ore being processed....

Organically-Modified Clay Minerals in Oil Sands: Characterization and Effect of Hydrothermal Treatment
DownloadFall 2017
The intimate association between bitumen components and clay minerals is an important feature of oil sands fine solids. These organically-modified clay minerals cause serious problems in Canadian oil sands production: hindering bitumen extraction, stabilizing water-in-bitumen emulsions, fouling...

The use of solvents for extraction of bitumen is attractive because no wet tailings are produced. Studies have already shown that hydrocarbon solvents can achieve the same level of bitumen recovery as the current aqueous extraction method. However, solvent recovery must be very efficient to avoid...
