Froth treatment (Athabasca oil sands) - Wikipedia

Froth Treatment is a process by which water and fine solids are removed from bitumen froth using hydrocarbon-based gravity separation. There are two different types of hydrocarbons used in Froth Treatment: a naphtha-based hydrocarbon and a lighter paraffinic solvent. Both produce a relatively clean bitumen product but only a paraffinic process produces a marketable product stream.

The curse of Fort Hills is finally lifted | Oil Sands Magazine

The Secondary Extraction plant will employ a High-Temperature Paraffinic Froth Treatment (HT-PFT) process, very similar to the one used by Imperial Oil and Shell. The Fort Hills deposit is relatively good grade with a slightly high strip ratio (indicating a larger volume of overburden needs to be removed in order to access the bitumen-rich ore).

Froth Treatment | Natural Resources Canada

Froth treatment is the process of eliminating the aqueous and solid contaminants from the froth to produce a clean bitumen product. The froth is first diluted with a hydrocarbon solvent to reduce the viscosity and density of the oil phase, thereby accelerating the settling of the dispersed phase impurities by gravity or centrifugation.
