At different stages during the extraction of bitumen from the Athabasca oil sands, the removal of unwanted fine solids  whether suspended in aqueous or non-aqueous liquids  continues to present serious challenges to the oil sands industry. These fine solids are unique in that their colloidal...

A major challenge to any “solvent-based” bitumen extraction technology is the removal of suspended fine solids from the hydrocarbon medium (i.e. diluted bitumen). To address this problem, we examined how colloidal solids could be made to aggregate in a hydrocarbon medium and thus be separated by...

Environmental concerns about water-based extraction necessitate the development of an alternative non-aqueous extraction method. One of the challenges that any non-aqueous extraction process is encountered is the elimination of suspended fine solids from solvent-diluted bitumen. This study...

In many applications, it is desired to separate unwanted fine particulates from a liquid by gravity settling. An efficient separation, however, will be feasible only if a combination of aggregation and sedimentation occurs. To understand the kinetics of such a process, a mathematical model that...

Multiphase flows with a dispersed phase of micron-sized solid particles are common to many industrial applications, ranging from wastewater treatment to metal purification. These particles are in a size range where surface forces are significant, and thus are likely to form aggregates. When these...

Cifuentes, Gustavo A.

Micron-size particle suspensions are very common in industrial processes such as mineral extraction and wastewater treatment. These particles are difficult to separate from the fluid media due to their size. The formation of aggregates increases the effective size of these particles, increasing...

Treating contaminated hot streams is essential to reduce water cooling/re-heating needs and greenhouse gas emission in water reclamation processes, such as the Canadian in-situ oil-sand extraction processes that produce contaminated water at 80-90 C. Membrane separation processes have become one...
