Spring 2010
The technique of Inverse Gas Chromatography (IGC) was employed for the study of the interactions between various organic solvents with various types of the major inorganic materials (clay minerals and sand) found in Alberta’s oil sands. Heat of adsorption (-∆H) was measured for each solvent with...

Atomistic Approach towards Sodium Citrate Role on Surface Properties of Silica and Clay Minerals
DownloadFall 2022
The use of sodium citrate as a secondary processing aid in combination with caustic significantly improved bitumen recovery, specifically in poor oil sands ores. The role of sodium citrate on wettability alteration of solid surfaces, benefiting bitumen liberation as well as improving bitumen...

Centrifuge Modeling and Large Deformation Analyses of Axially Loaded Helical Piles in Cohesive Soils
DownloadSpring 2022
In the past decades, helical piles have gained increasing popularity in civil engineering practice as an option of deep foundations. The design of axial load capacity of these piles relies on an appropriate selection of failure mode. Currently, the axial failure modes of multi-helix piles...

Characterization of a landslide-prone glaciolacustrine clay from the Thompson River Valley near Ashcroft, British Columbia
DownloadFall 2017
Several large landslides have occurred in the Thompson River Valley near Ashcroft, British Columbia. The movement of these landslides have presented challenges for the operation of the two national railways that traverse this valley. The landslides are multiple retrogressive, translational,...

Effects of Surface Contamination and Water Chemistry on the Behaviors of Illite, Kaolinite and Montmorillonite in Organic and Aqueous Media
DownloadSpring 2016
Clays, due to their specific surface area and electrical charge density, are among the most active minerals in aquifers, oil and gas reservoirs, and tailings ponds. Clays, in tailings, are a significant ongoing environmental concern in the mining and oil sands production industries and clay...

Molecular Dynamics Study of the Interactions between Cations/Carbon Dioxide and Selected Mineral Surfaces
DownloadSpring 2018
Undoubtedly, we need to become increasingly aware of the changes and problems introduced to our environment. Oil sands industrial waste disposal and greenhouse gas emission are the two major by-products of the industrial processes that cause environmental concerns, such as huge tailing ponds and...
