  • Post-conditioning oil sand slurry blending for improved extraction performance
    Patent number: 9068124
    Abstract: The invention is directed to a process for extracting bitumen from poor oil sand ore involving mixing the poor oil sand ore with heated water to produce a slurry, and conditioning the slurry to yield a poor ore stream. In a separate train, good oil sand ore is mixed with heated water to produce a slurry, and conditioned to yield a good ore stream. Both the conditioned poor ore and good ore streams are combined in specified proportions to yield a blended slurry which is then fed to a primary separation vessel to produce primary bitumen froth.

  • Bitumen froth storage and separation using an improved froth tank
    Patent number: 8919575
    Abstract: The invention is directed to a process for separating bitumen froth into an upper bitumen-rich, reduced-solids layer, and a lower concentrated solids layer using a cone-bottomed, raked froth tank. The process involves introducing bitumen froth into the froth tank; rotating at least one movable picket through the bitumen froth; recovering the upper bitumen-rich, reduced-solids layer; and withdrawing the lower concentrated solids layer from the tank.
