Mechanisms of Aggregation and Separation of Water and Solids from Bitumen Froth using Cluster Size Distribution
DownloadFall 2016
The large-scale corrosion and equipment damage caused by water and solids respectively in bitumen froth necessitate their removal using various methods. This study is aimed at understanding how water and solids aggregate (water-water, water-solid and solid-solid) in bitumen froth and what the...

The impact of mixing on water removal from diluted bitumen and bitumen froth is studied, with the goal of maximizing demulsifier performance. The relative effects of bulk concentration, mixing intensity, mixing time and injection concentration on the demulsifier performance are evaluated. A...

Bitumen froth is an intermediate product of bitumen upgrading which must be treated to remove solids and water. De-mineralization and de-watering occur through a settling operation in which the addition of a diluent and a demulsifier are crucial to its success. This work explores the effect of...

The impact of mixing on diluted bitumen de-watering is studied in two stages using a fractional factorial design of experiments. The first stage evaluates the relative effects of bulk demulsifier dosage, local maximum energy dissipation, and mixing time. The second stage of experiments evaluates...

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...
