Solvent Extraction of Bitumen from Oil Sands

Oil sands, tar sands or, more technically, bituminous sands, are a type of "unconventional" oil/petroleum deposit. The oil sands are loose sand or partially consolidated sandstone containing naturally occurring mixtures of sand, clay, and water, saturated with a dense and extremely viscous form of petroleum technically referred to as bitumen (or colloquially tar due to its similar appearance ...

Bitumen Recovery - an overview | ScienceDirect Topics

At the extraction plant more hot water is added to this mixture of sand, clay, bitumen, and water in a large separation vessel where settling time is provided to allow the various components to separate. During separation, bitumen froth rises to the surface, where …

Waterless oil sands extraction | Engineering at Alberta

James G. Speight PhD, DSc, in Oil Sand Production Processes, 2013. 3.4 Other Processes. It is conceivable that the problems related to bitumen mining and bitumen recovery for the oil sand may be alleviated somewhat by the development of process options that require considerably less water in the sand/bitumen separation step. Such an option would allow a more gradual removal of the tailings …

Understanding Water‐Based Bitumen Extraction from ...

Mar 23, 2015· The Canadian oil sands (or tar sands) are a large area of petroleum extraction from bitumen, located primarily along the Athabasca River with its centre of activity close to Fort McMurray in Alberta, approximately 400 km northeast of the provincial capital, Edmonton.

Waterless oil sands extraction | Engineering at Alberta

In the present study, solvent extraction of bitumen from Xinjiang oil sands was investigated using solvents, such as alkanes, toluene, and chloroform, and mixed solvents, such as n-hexane–ethyl acetate and cyclohexane–methyl ethyl ketone (MEK). The n-heptane asphaltene content in the extracted bitumen was measured by saturate, aromatic, resin, and asphaltene (SARA) analysis, and the ...

Bitumen | The Canadian Encyclopedia

Roughly 500 km 2 of the 140,000 km 2 oil sands deposit in Northern Alberta is currently undergoing surface mining activity. This is about 3% of total oil sands surface area or 20% of oil sands reserves. Surface mining uses truck and shovel technology to move sand saturated with bitumen from the mining area to an extraction facility.

What Are Tar Sands? | Union of Concerned Scientists

The environmental impact of the oil sands is an issue that has been extremely divisive. As with the extraction and use of any fossil fuel, negative environmental effects arise as a result of the extraction, upgrading, and processing of bitumen from the oil sands. Although some steps are being taken to reduce the severity of these impacts - such as reclamation - there are still associated ...

sands) are being utilized. Oil sands contain bitumen, which can be processed into a synthetic crude oil. A region of boreal forest in Alberta, Canada, that covers a deposit of oil sands will be cut and removed during the process of bitumen extraction. It is estimated that the deposit contains 73 billion barrels of recoverable bitumen.
