Spring 2011
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...

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...

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...

Interactions of finely dispersed abrasive particles in chemical mechanical planarization (CMP) slurries play a vital role in determining the polishing performance. In this study, coupled influence of hydrodynamic and colloidal interactions on the attachment of nanosized ceria (CeO2) particles to...

Underground Coal Gasification (UCG) is a process in which coal is converted to syngas in-situ. UCG has gained popularity recently as it could be used to extract energy of deep-lying coal seams, and it reduces the footprints attributed to the gasification process. In this study, two models have...

Coal Liquefaction Liquid Quality: Influence of Temperature and Heating Approach on Solvent Extraction of Coal
DownloadFall 2014
This project evaluated the impact of reaction temperature and of additional heating steps on the quality of the liquids obtained from solvent extraction of a lignite coal with tetralin. The points of focus were the coal liquid yield, physical properties, aromatic content and iron pyrite...

Bitumen, as one of the most important unconventional sources of energy, has long been an attractive source for production of liquid fuels. It is important to improve the yield and quality of the useful products resulting from bitumen upgrading processes so that the best outcome can be achieved...

Spring 2015
Previous studies on the extraction of liquid products from coals have focused mainly on increasing the yield, with very little emphasis on the quality of the liquid products. The main goal of this study is to achieve a balance between the yield and quality of the coal derived liquids. The first...

The removal of solid particulates from crude oils and hydrocarbon streams is a common challenge in refining. Finding a method for efficient removal of the suspended solids in the oil streams is the main objective of this work. Paraffinic and aqueous treatment and the combination of these two...
