This project was initiated to study the H2S removal process from liquid sulfur and later extended to generic liquid degassing scenarios. Enersul HyspecTM Degassing Process was first field tested so that comparison could be made with new units to be engineered. Two new degassing units were...
Commercial Magnafloc 1011and in-house synthesized Al-PAM were used as flocculants for model tailings, laboratory extraction tailings and tailings from paraffin froth treatment unit. The polymers were tested for their flocculation ability in settling and filtration. For model tailings, both...
A study of the colloidal stability of mixed abrasive slurries of silica and ceria nanoparticles for chemical mechanical polishingDownload
Slurry stability is an important factor in Chemical Mechanical Polishing (CMP) efficiency. However, few studies have been done in this respect. In settling tests at pH 4, adding various amounts of ceria to colloidal silica slurries was shown to change the stability of the resulted mixed abrasive...
Interfacially Active Magnetic Nanoparticles for Efficient Oil/Water Separation from Oil-in-Water or Water-in-Oil EmulsionsDownload
The emulsions, either oil-in-water (O/W) or water-in-oil (W/O) emulsions, are inevitably formed during the industrial production processes and the daily household activities. The O/W emulsions such as crude oil-in-water emulsions or oily wastewaters generated from the industrial fields, oil...
Filtration performance of mineral concentrate is mainly controlled by solid particle size and surface hydrophobicity. Filtration of coarser particles with more hydrophobic surfaces produces better filtration performance characterized by higher filtration rate (U) and lower final moisture content...
Management of oil sands tailings from bitumen extraction operations remains a challenge for mineable oil sands producers. Promoting fine solids settling in tailings ponds is key to treating oil sands tailings. Present study explores two methods of tailings treatment – ATA process and polymer...
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,...
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...
The spontaneous displacement of a fluid in another immiscible one on a solid surface is essential for many technical applications, such as painting, detergency, bitumen extraction and enhancing oil recovery. This project was motivated by exploring a process of high viscosity bitumen displaced by...
Caustic is the most commonly used process aid to improve processability of mineable oil sands ores in the Athabasca region. The addition of caustic adjusts the pH of the extraction process, disperses clays, and acts as a water softener. Understanding how these changes affect the fundamental...
