sand slurry

Construction started in 1996 on the first production train using hydrotransport of oil sand slurry.

Others have since converted to this approach, which, when combined with pipeline hydrotransport of oil sands slurry, results in significant energy savings.

Laboratory flume deposition tests were carried out to study the physical phenomena associated with the deposition of a sand slurry to form a hydraulic fill.

The polder guide dams were built using the geotextile tube method, where porous sausage-shaped bags are pumped full of sand slurry.

At Aurora, oil sand slurry is hydraulically transported by pipeline at a rate of 8,000 tonnes of oil sand per hour.

Planned activities include mining with large-scale shovels and trucks, hydrotransport of oil sand slurry, a low energy extraction process, and froth pipelining.

A slurry pit will receive the sand slurry and concentrate the sand slurry to the required density.

About 6,300 gallons of a produced water-crude oil mixture spilled because of an overflow of a sand slurry tank at the field's central facility pad, the department said.

A hydrotransport pipeline feeds up to 8,000 tonnes of oil sand slurry per hour to the primary separation vessel (PSV) at Syncrude's Aurora Mine.

AsPen AC is a specially modified asphalt emulsion formulated for sealing, rejuvenating, beautifying and waterproofing asphalt pavements, chip seals, sand slurries, and other aggregate surface treatments.

A hybrid of sedimentation and filtration is the recent method in which a sand slurry moves down a tower, and water is passed from the centre to the perimeter across the sand stream.

Oil sand from the mine operation is mixed with hot water and caustic and the oil sand slurry is then transported by pipeline to the extraction plant where it feeds directly into the primary separation vessels.

Most of their work focuses on the behaviour of bitumen droplets in oil sand slurries, on the stability of water droplets in diluted bitumen, and on the interactions between mineral particles in fine tailings.

The use of cementitious grout to replace the sand slurry backfill resulted in greater pile load carrying capacity as the failure surface was transferred to the grout (backfill) – native soil interface instead of the pile–backfill interface.

Conventional measurement techniques are not suitable for fine tails, and a special slurry consolidometer, with a clamping device to prevent seepage-induced consolidation, was designed to determine the hydraulic conductivity of the fine tails and nonsegregating fine tails – sand slurries.
