Clay minerals such as montmorillonite and kaolinite are considered as fine solids that could adversely affect bitumen extraction from oil sands. Colloidal forces between bitumen and fine clays and between bitumen and bitumen in the presence of montmorillonite clays were measured with an atomic force microscope.

It is demonstrated that bitumen can be separated from "water-wet" Alberta oil sands and "oil-wet" Utah oil sands using a so-called analogue ionic liquid (IL) based on deep eutectic mixtures of choline chloride and urea (ChCl/U) together with a diluent such as naphtha.

The change in colour of the black tar sand is an indication of high extraction efficiency. Hence, owing to high demand for conventional oil supply in the country and the urgent need for an alternative source of oil, the bitumen extract can serve as an alternative source of unconventional oil supply in Nigeria and feedstock in refineries.

Crude bitumen/tar sand is obtained from the processing of crude oil, and is often further refined by solvent extraction to obtain high-quality bitumen. It is an affordable option due to its high availability, but quality is not consistent as it depends on the quality of crude oil used in its production. ... For example, if you are looking for ...

2.2 Past Studies on Bitumen Extraction in Nigeria . A study on Solvent extraction of bitumen from Nigerian tar sands using toluene was investigated [5]. Pulverization of the tar sands followed by agglomeration in a mechanical shaker resulted in spherical agglomerates having higher bitumen contents than the mined tar sand.

Canada has the world's third largest oil reserves, mostly located in the oil sands. Although oil sands and shale deposits are found all over the world, the Alberta oil sands are water-wet, making bitumen extraction feasible using just hot water.Learn more about this unique deposit, and some of its chemical and physical properties.

Bitumen is a dark brown to black colour glue material majorly used in the construction of bound layers of pavements. It is treated as a hazardous material because of its higher PAH (polycyclic aromatic hydrocarbons) content and presence of hydrogen sulphide. These characteristics of conventional bitumen affect humans as well as the …

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 …
