O'Carroll and Sleep [, ] examined the effect of temperature on interfacial tension and viscosity during hot water flushing, showing that heat can have a significant impact on contaminant removal. However, changes in groundwater hydraulics and contaminant transport due to buoyant flow were not by:
Nearly half of the global oil sands reserves, approximately trillion barrels, are located in northeastern Alberta, Canada (Morgan, ). Athabasca oil sands consist of ~10 wt.% bitumen (1) while the remaining constituents are mainly inorganics such as silica sands and, to a lesser extent, fine clays and water (Shaw et al., ). (see "Surface and Interfacial Phenomena Related to the Hot Water Processing of Athabasca Oil Sands," J. G. Special and S. E. Moschopedis, Alberta .
Tar sands’ water allocations accounts for 65% of the water withdrawals from the Athabasca River every year. Tar Sands water use requirements are resulting in lower water levels in freshwater aquifers, rivers, streams, lakes, ponds and wetlands. LINK. It takes three to five barrels of water to produce one barrel of oil. This banner text can have markup.. web; books; video; audio; software; images; Toggle navigation.

CrossRef Google Scholar Author: Victor P. Janule. The Clark hot water bitumen extraction process generates several water types with differing chemical qualities (Wallace et al., ).
The Athabasca River and on-site aquifers are the primary sources of raw water to the oil producers in the Athabasca deposit (Allen, ).
Raw water undergoes chemical alteration once it contacts the ore due to. Abstract: A special kind of nonaqueous foam known as bituminous froth is produced during the application of the hot-water flotation process to Athabasca oil sands, a large-scale commercial application of mined oil sands technology.
These froths are multiphase. Studies of the processibility of a variety of types of Athabasca oil sands have been carried out to further elucidate the physical action of natural surfactants in the hot-water flotation process.
In particular, the interfacial tensions between bitumen and aqueous phases were measured at process temperature Cited by: Bitumen, separated from oil sands by the hot water extraction process, contains ultra‐fine (inorganic solids (BS).
Surfaces of BS particles are coated with toluene insoluble organic matter (TIOM). This organic material is polar and aromatic with contributions from both humic and asphaltene‐like by: The hot water flotation process separates bitumen from the associated minerals by exploiting differences in their bulk-and surface-physical properties.
In the ‘conditioning’ step, oil sand is slurried with the addition of heat, mechanical shear, air (by entrainment) and sodium by: The conceptual model is illustrated schematically in Figure first, second, and fourth columns are from Hockley and Omotoso (, this volume, figure 1), with the fourth column simplified to show only the pathways of mineral solids, including clays, through oil-sands of the operations takes advantage of or is affected by one or more of the fundamental physical processes.
Abstract. Bubble size is an important factor in the flotation of oil and other contaminants from industrial wastewater. A novel cyclone flotation technique—the air-sparged hydrocyclone (ASH) technology—offers fine bubble size distribution required for the efficient removal of dispersed oil and has a specific capacity times greater than conventional flotation by: 5.

Management and reclamation of large inventories of legacy and fresh mature fine tailings (MFT) represent a continuing and significant challenge to surface mine operators in the Alberta Oil Sands because of the complex chemical and physical behavior of these tailings.

when first organized as a. Oil sands are significant unconventional oils [9,10], and the utilization of unconventional oil is a hot research issue.
The methods of obtaining bitumen from oil sands consist of the hot water-based extraction (HWBE) process [12,13,14,15], the solvent extraction process [16,17], and Cited by: 1. A process suitable for operation at a mine site for recovering a hydrocarbon from a hydrocarbon bearing sand comprising the steps of mixing a chemical additive with a chemical composition and with a hydrocarbon bearing sand containing hydrocarbon and residual solids including clay, at a temperature to form a : Armand A.
Gregoli, John A. Hamshar, Daniel P. Rimmer, Erdal Yildirim. To recover bitumen from the oil sands, water‐based processes derived from the pioneering Clark Hot Water Extraction (CHWE) technology (Clark and Pasternack, ) are widely used in the industry.
In these processes, hot or warm water is added to oil sands to form a slurry from which bitumen is liberated from the sand grains and recovered as Cited by: The slurry is aerated to produce essentially sludge-free tailings and a mixture of hydrocarbon, aqueous phase and residual solids including clay.
The process further comprises the step of separating the mixture of the hydrocarbon, the aqueous phase and the residual solids including clay from the essentially sludge-free by: Solubility of water in Athabasca Bitumen Satyro, Shaw, Yarranton, Fluid Phase Equilib ;– API Technical Data Book: Petroleum Refining, 6th ed.

You can.Eight oil sands ores were tested in order to quantify the levels of humic acids in these samples through the alkali extraction test originally developed to determine the oxidation of bituminous metallurgical coals.
The test gives a concentration of humic acids released from ores, which in combination with the measurement of the total organic carbon content in the alkali extracts provides a.
