Extending Depletion Flocculation Phase Behavior Models to Partially Soluble and Aggregating Colloids—Asphaltenes
DownloadFall 2015
Mixtures of colloids + non-adsorbing polymers + good solvents are well known to exhibit multiphase behaviors that are driven by the depletion flocculation mechanism where one phase, designated a colloid gas, is largely comprised of polymer and solvent, while the other phase, designated a colloid...

Flocculation and dewatering of kaolinite suspensions and oil sands mature fine tailings using dual polymers
DownloadSpring 2015
The development of a method to consolidate and dewater Athabasca oil sands mature fine tailings (MFT) is one of the major challenges facing Alberta’s oil sands industry. This thesis presents studies performed on the flocculation and dewatering of kaolinite suspensions (the major clay component...

The oil sands are a vital part of the provincial economy in Alberta and oil production in this sector produces large amounts of waste called tailings. The tailings consist of a slurry of clay suspended in process water with residual bitumen present. Reclamation of the land that the tailings ponds...

Reclamation of oil sands fluid fine tailings (FFT) is a challenge for mine operators in Alberta because of their high water content and slow self-weight dewatering. Chemical additives, including polymer flocculants, are used by operators as a treatment technology to reduce volumes and increase...
