摘要： A process for extracting bitumen from oil sand, comprising: mixing oil sand with process water to produce an oil sand slurry containing bitumen, sand, water and entrained air; conditioning the oil sand slurry; optionally flooding the conditioned oil sand slurry with flood water to dilute the slurry, if required; introducing the slurry into a primary separation vessel wherein separate layers of primary bitumen froth, middlings and sand tailings are formed; removing a portion of the primary bitumen froth from the primary separation vessel and recycling the portion of primary bitumen froth to that step of the process upstream of the primary separation vessel to join and mix with the feed stream moving to the primary separation vessel; and thereafter retaining said feed stream in said primary separation vessel to produce primary bitumen froth.

摘要： A method and apparatus for measuring the flow rate of bitumen froth through a pipeline is provided. A flow meter device is provided including a conduit comprising an approach section having a diameter less than the diameter of the pipeline and a venturi section having in series a converging section, a throat section and, optionally, a diverging section, the converging section of the venturi section being disposed relative to the approach section, and a means for measuring the pressure difference ΔP between two points that are separate from one another in the flow direction, one point being on the approach section and the other point being on the throat section. In one embodiment, a heating means for heating the conduit is provided.
