    摘要: A process for recovery of hydrocarbon diluent from tailings produced in a bitumen froth treatment plant comprises introducing the tailings into a vacuum flash vessel maintained at a sufficiently low sub-atmospheric pressure to vaporize the major portion of the contained diluent and some water. The residual then pool near the bottom of the flash vessel. Steam is then introduced into the tailings pool for vaporizing residual diluent and some water.

    摘要: A method and a mix box for mixing oil sand and water to form a substantially uniformly mixed oil sand slurry is provided. The mix box has an open top end for receiving pre-crushed oil sand and water and a sloped bottom end having a discharge outlet and includes a plurality of profiled shelves positioned within the mix box. The substantially uniformly mixed oil sand has a substantially uniform flow distribution and therefore, when screened, reduces uneven wear on the screens.

    摘要: A process for flocculating and dewatering oil sands fine tailings is provided, comprising: adding the oil sands fine tailings as an aqueous slurry to a stirred tank reactor; adding an effective amount of a polymeric flocculant to the stirred tank reactor containing the oil sands fine tailings and operating the reactor at an impeller tip speed for a period of time that is sufficient to form a gel-like structure; subjecting the gel-like structure to shear conditions in the stirred tank reactor for a period of time sufficient to break down the gel-like structure to form flocs and release water; and removing the flocculated oil sands fine tailings from the stirred tank reactor when the maximum yield stress of the flocculated oil sands fine tailings begins to decline but before the capillary suction time of the flocculated oil sands fine tailings begins to substantially increase from its lowest point.
