Froth Treatment Explained | Oil Sands Magazine

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.

Process for Solvent Extraction of Bitumen from Oil S

Water-based bitumen extraction technology from mineable oil sands faces major challenges of high water usage and tailings disposal. In the present study, a process for solvent extraction of...

Froth Treatment in Athabasca Oil Sands Bitumen

Bitumen froth treatment is an integrated process step in the Athabasca oil sands bitumen recovery operations. Its objective is to separate mineral solids and water from the bitumen froth. The bitumen froth is diluted with naphthenic or paraffinic solvents to lower its viscosity to facilitate the separation; therefore, bitumen froth treatment is the removal of inorganics (mineral particles

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.

Paraffinic Froth Treatment | Oil Sands Magazine

Froth Treatment is a process by which water and fine solids are removed from bitumen froth produced in Extraction using hydrocarbon-based gravity separation. In a Paraffinic Froth Treatment facility, a paraffinic solvent is used as the diluent, producing a very clean final product that can be sold directly to market without an upgrading step.

Bitumen Extraction Explained | Oil Sands Magazine

Oil sands slurry produced in the Slurry Preparation Plant SPP contains about 50-55% sand and less than 10% bitumen. The purpose of Extraction is to recover the bitumen portion, while rejecting the heavy solids. This is achieved through a simple water-based gravity separation process, most of which

DILUTED BITUMEN SLURRY AND FROTH, SOLVENT

BITUMEN SLURRY AND FROTH, SOLVENT. Typical end products. Synthetic crude oil, upgraded bitumen. Chemical curve: R.I. per Solvent/Bitumen Ratio at Ref. Temp. of 20˚C. Introduction. Oil sands, tar sands or heavy oils are a mixture of water, sand, clay and bitumen. The bitumen can be. extracted from the mixture and be upgraded into a

US Patent for Solvent process for bitumen seperation

In a preferred embodiment, the invention involves a method for cleaning bitumen froth containing water and particulate solids contaminants, said froth having been produced by a water extraction process practised on oil sands, comprising: adding paraffinic solvent to the froth in sufficient amount to produce a solvent to froth ratio (“S/F...

Process for Solvent Extraction of Bitumen from Oil

Water-based bitumen extraction technology from mineable oil sands faces major challenges of high water usage and tailings disposal. In the present study, a process for solvent extraction of bitumen from Athabasca oil sands was investigated. In this process, oil sand is mixed with light hydrocarbon solvents, and the solvent–bitumen solution is separated from the mineral solids by centrifugal...

Stability and settling characteristics of solvent-diluted

1.. IntroductionBitumen from the shallow oil sands deposits in northern Alberta, Canada is recovered through surface mining, hot water extraction, and froth treatment,,,,.The froth from an oil sands extraction circuit typically contains 60. wt% bitumen, 30 wt% water, and 10 wt% solids.. To meet downstream process specifications, the water and solids in froth have to be removed.

Clay minerals in nonaqueous extraction of bitumen

Clay minerals in nonaqueous extraction of bitumen from Alberta oil... unlike the water extraction process, the solvent extraction procedure was not sensitive to the fines and clay contents of the oil sands ores or to the ore grade, at least for medium and high-grade ores....
