Solvent based extraction has the potential to supplant the current hot water based extraction process as the industry standard method for recovering bitumen from mined oil sand. It has the potential for higher bitumen recovery that is less sensitive to the grade of oil sand ore being processed....

This research comprises four integral parts. Each part focuses on one aspect of the general problem of drug delivery by respiration. The morphological features of human respiratory tract, the dynamics of inhaled pharmaceutical particles, and the mechanics of inhaler devices are particularly taken...

The bitumen production from oil sands surface-mining operations produces large volumes of mineral wastes called tailings. Characterization of the oil sands tailings is of importance to monitor their state for trafficability and reclamation issues, to assess the tailings operation performance, and...

A study was implemented to evaluate different alternatives of soil cover systems for the closure of approximately 1539 Mt of waste rock at the Antamina Mine (Peru). The soil covers were designed to limit water percolation to the underlying waste rock, by combining a store/release and low...

The minable oil sands extraction process can be understood on a scale of a single oil sand grain. When the oil sand ore is mixed with warm water, each sand granule is initially covered with bitumen film which ruptures under the composite effect of shear and interfacial forces, while water...

The current water-based method of bitumen extraction requires withdrawal of fresh water from the Athabasca River — a practice which leads to the continual buildup of tailings ponds and other environmental concerns. As Alberta’s bitumen production is expected to more than double by 2020, there is...

This thesis aims to demonstrate the feasibility of using System Dynamics (SD) techniques to develop a transparent, open-source and reproducible model capable of simulating long-term soil water dynamics in a tailings-cap system subject to upward flux from a consolidating tailings substrate. The...

Feng, Y., Li, X.

Oil sand processing in northern Alberta generates a large amount of water saturated fine-grained material (or fine tails) as a byproduct. Fine tails are a mixture of fine mineral particles (<44µm in diameter), small amounts of bitumen, and a large amount of water. Some consolidation of the...

Removal of a drop from its substrate may be gradually (e.g. evaporation) or all at once (e.g. shedding). In this thesis, drop adhesion force as a base for understanding the all at once removal of a drop from its substrate, and drop evaporation in room temperature as one of the gradual removal...

We investigate experimentally the early time dynamics of spontaneous spreading of silicone oils with various viscosities at elevated surrounding pressures. The surrounding medium pressure is increased in a monotone fashion starting from atmospheric pressure to a maximum value of 30 megapascal...
