The purpose of this study is to investigate the impact of solvent addition to bitumen froth on the wettability of froth solids. The wettability of solids determines the transportation/partitioning of the solids between phases, which in turn affects the solids and water rejection in a Clark hot...

The mining of oil sands ore and extraction of bitumen produces aqueous slurries containing bitumen, coarse sand and fine clays. The performance of key process units is highly dependent on the rheology of “carrier fluid”, which is comprised of the fine solids and water. Although viscosity is...

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...

Canadian oilsands bitumen represents one of the largest petroleum reserves in the world, but extraction of that resource raises significant environmental, operational and quality-related challenges. Current extraction processes are water intensive, generating high volume tailings ponds that are...

The objective of this dissertation was to find novel adsorbents addressing problems associated with acid gases. They are the most common contaminants in multiple aspects of petroleum processing and combustion gas clean up, which reduce the efficiency of petroleum refining and product quality....

Oilsands tailings are a waste product comprising primarily a stable alkaline suspension of clay in water. This waste product of oilsands mining is environmentally hazardous to store and expensive to safely dispose of. This work presents two novel ideas for dealing with the waste. The first is...

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...

Canada has the third largest oil reserves in the world where 97% of these reserves are located in the oil sands, Alberta province. The product resulted from the extraction of oil sands reserves is called bitumen which can be diluted and shipped to the market or it can be proceeded and upgraded...

Process industries involve processes that have complex, interdependent, and sometimes uncontrollable/unobservable features that are subject to a variety of uncertainties such as operational fluctuations, sensory noises, process anomalies, human involvement, market volatility, and so forth. In the...

Non-aqueous solvent extraction of bitumen from oil sands has the potential to replace the existing hot-water extraction process. The benefit of non-aqueous extraction process includes high bitumen recovery, reduction of fresh water demand for extraction and the elimination of resulting tailing...
