The non-aqueous extraction process involves dilution of mined oil sand with an organic solvent (the “diluent”), followed by separation of unwanted materials (clays, silica sand, connate water, etc.) from the diluted bitumen. The main focus of this research is on the removal of fines solids from...

Dewatering of the oil sands mature fine tailings (MFT) is studied through pressure filtration following treatment by dual polymer flocculants. Polymer pairs consisting of anionic polyacrylamide (A3335) and cationic polyDADMAC (Alcomer 7115), and A3335 and non-ionic polyethylene oxide (PEO) are...

Water-mediated adhesion of oil sands on solid surfaces at low temperature and possible solutions to mitigate adhesion
DownloadSpring 2022
Adhesion of frozen granular materials on solid surfaces creates various problems for surface cleaning, reduces the carrying capacity of vehicles, and increases energy consumption for inland transportation. Here in the first part of this thesis, water content demonstrates to determine the adhesion...
