  • Patent number: 9956503
    Abstract: A solvent diluted bitumen is produced by a method that includes adding paraffinic solvent to bitumen froth to form a solvent diluted bitumen froth, and discharging the solvent diluted bitumen froth into a vessel, such that settlement of the solvent diluted bitumen froth in the interior of the vessel establishes a heavier phase zone, a lighter phase zone, and an interface. A discharge point is located above the interface and within the lighter phase zone. Lighter phases separate up toward an overflow outlet of the vessel while heavier phases separate down toward an underflow outlet of the vessel. The solvent diluted bitumen is collected from the overflow outlet, and a solvent diluted underflow stream is collected from the underflow outlet.

  • Patent number: 9919320
    Abstract: A flotation separation apparatus for separating particles in suspensions, feeds slurry containing the particles through an inlet into a contactor where gas is fed through an inlet to mix with the slurry, for example in a downwardly plunging jet, to form a gas-liquid bubbly two-phase mixture under pressure from an outlet restriction in a throttling duct. The mixture is passed through a flow manipulator configured to induce a high energy dissipation rate, for example by way of a Shockwave formed in a diverging section of the throttling duct reducing the size of the bubbles and brining those bubbles into intimate contact with particles in the mixture which is released into a separation cell where a flow manipulating draft tube is provided to reduce turbulence in the mixture. Alternative apparatus and methods for inducing the high energy dissipation rate and for reducing turbulence in the mixture are also described and claimed.

  • Patent number: 9908802
    Abstract: Treating an organic effluent is disclosed. The effluent is fed in a continuous flow at a rate q via a first chamber maintained at a first pressure and/or directly through a first narrowing to a second chamber or container maintained at a second medium pressure by the injection of air into the second chamber at a rate Q in order to obtain an emulsion in the second chamber. A head loss is generated in the emulsion optionally modified by a second and/or third narrowing or a feed valve for a third chamber maintained at a third pressure in the region immediately downstream of the second or third narrowing and/or valve. A flocculant is injected into the region of the third chamber. The emulsion at atmospheric pressure then being degasified and the emulsion thus degasified being recovered in a filtration or decanting device.
