  • Physics in the oil sands of Alberta

    To liberate bitumen from the sand grains, the slurry is pumped through a hydrotransport pipeline (shown in figure 3) for 3–5 km. Turbulence in the pipeline ablates the lumps and separates the bitumen from the sand grains. At the same time, bitumen droplets attach to entrained air bubbles. The slurry of sand and aerated bitumen then enters a

  • Oil Sands Processing

    Aug 06, 2020Oil sands are a combination of sand, clay and water that contain a heavy crude oil variant called bitumen. 1 But, this complex hydrocarbon is almost solid at room temperature and does not flow without extensive processing. 2 Subsequently, there are two ways to extract the bitumen: mining or in situ. 3 Both are complex, energyintensive and expensive processes. 3 As a result, oil sands

  • Factors Governing Friction Losses in Self

    The slurry is prepared for extraction in pipelines as it is being transported from the mine to the extraction plant. Bitumen, which is a very heavy crude (viscosity Pas at 50C), is released from the oil sand and subsequently separated from the other oil sand constituents (sand and clay) in large gravity settling vessels.
