Ifill, Roy O.

Poor settling of solids increases land requirement for tailings containment and imposes severe constraints on the water balance. Consequent to these considerations, the alternating current electrocoagulation (AC/EC) technique emerged as a candidate for enhancing the settling behaviour of...

This work investigated different acid catalysts and olefinic alkylating agents for the alkylation of an industrial asphaltenes feed. The working hypothesis was that alkylation would change the solubility parameter and increase the H/C ratio of asphaltenes sufficiently to cause some asphaltenes...

Phase transitions of the alkali metal carboxylates have been explored by many researchers. A fair amount of scatter can also be observed in the published data. The aim of this study was to systematically study the thermal behavior of lithium, sodium, potassium, cesium and rubidium carboxylates,...

Oil sands industry, with the collaboration of its research partners, has been striving to come up with cost effective and environmentally friendly technology for de-watering of mature fine tailings (MFT). Overall objective of present study was to determine the optimum dosage of suitable polymer...

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...

Karkooti, Amin

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...
