Spring 2016
A technique to visualize miscible displacement in porous media using laser and the analysis of the results for different processes are presented in this thesis. After saturating the model made of different sized glass beads with oil, solvent was introduced either under dynamic (injection and...

A Molecular Dynamics Approach towards the Interfacial Properties of Sulfide- and Clay-Minerals
DownloadSpring 2019
Interfacial properties have a regulatory role in processes which involve the coexistence of different phases. Although such macro-scale properties are determined by the intrinsic nature of the interface-sharing phases, it is possible to alter them in favor of the process objectives. This,...

A Molecular Dynamics Study of the Dissolution of Asphaltene Model Compounds in Supercritical Fluids
DownloadSpring 2011
The demand for a new solvent to treat oilsands was behind the purpose of this project; molecular dynamics simulation was used in this study. Supercritical water, supercritical carbon dioxide and other selected organic solvents in their supercritical state were studied. Meso-tetraphenyl porphyrin...

A Preliminary Study on Pyrolysis and Gasification of Asphaltenes and Coal-Asphaltenes Slurry in Entrained Flow Reactor
DownloadFall 2012
The aim of this work is to study pyrolysis of coal-asphaltenes slurry in an atmospheric entrained flow reactor. Athabasca asphaltenes and Genesee coal, both from Alberta in Canada, were selected as the feedstock. Char characteristics and the structure of asphaltenes and slurry chars including...

Spring 2011
A Surface Forces Apparatus (SFA) was used in this study to investigate the fundamental surface forces in oil sand processing research. Asphaltene coated surfaces were chosen as the research topic due to the critical role of asphaltenes in oil sands processing, from bitumen extraction, froth...

Activation of Delayed and Fluid Petroleum Coke for the Adsorption and Removal of Naphthenic Acids from Oil Sands Tailings Pond Water
DownloadSpring 2011
Oil sands companies produce substantial quantities of tailings known to contain high concentrations of dissolved organic by-products. The use of petroleum coke was proposed as a potential adsorbent for organic contaminant removal from tailings pond water. Physical activation was used to create a...

Two alkyl-bridged aromatic compounds, with molecular weights of 899.70 g/mol and 1127.99 g/mol, were thermally cracked with 1-hexadecene, 1- octadecene, or trans-stilbene, in a batch microreactor at 375–430 °C for 15 to 45 min. The objective of the study was to investigate the kinetics of the...

Two separations are necessary to enable the post-combustion capture of CO2. The fraction of CO2 in a flue gas stream must first be separated from the diluents present and then the concentrated stream of CO2 must be thoroughly dried in order for it to be compressed for sequestration. This work...

Adsorbents for the Removal of Naphthenic Acids from Oil Sands Process Water: Investigation of Reclamation Materials from Surface Mining of Oil Sands and Development of Biochars from Biological Sludge and Peat
DownloadSpring 2023
Crominski da Silva Medeiros, Deborah C.
Oil sands process water (OSPW) is generated in high quantities during the extraction of the bitumen from the oil sands. Naphthenic acids (NAs) are recalcitrant compounds, corresponding more than 50% of all organics in OSPW. The efficient management of OSPW is of importance to guarantee efficient...
