EFFECT OF SOLVENT DEASPHALTING PROCESS ON THE PROPERTIES OF DEASPHALTED OIL AND ASPHALTENES FROM BITUMEN
DownloadFall 2017
Asphaltenes are a solubility class of bitumen known to have undesirable properties. As asphaltenes are insoluble in paraffinic solvents, they can be separated from bitumen by adding a solvent such as n-pentane or n-heptane to produce better quality deasphalted oil (DAO). This process is called...

Hydrothermal Treatment of Bitumen Froth at 250 °C: Impact on Bitumen Properties and Role of Clay Minerals
DownloadFall 2023
Bitumen froth produced in the hot water extraction process of mined oil sands consists of about 60 wt % bitumen, 30 wt% water and 10 wt% mineral solids. To convert the bitumen in bitumen froth into a marketable product, the water and solids need to be separated. Solvent-based froth treatment...
