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...

In oil sands extraction, the removal of heavy materials from a bitumen feed is often facilitated by solvent addition treatment processes. These processes mix solvent with bitumen feed to cause the precipitation of heavy products. The settling properties of these heavy products as they separate...

Oilsands bitumen produced from Alberta, Canada contains 14–20 wt.% n-pentane insoluble asphaltenes. Separation of asphaltenes from the bitumen by solvent deasphalting has the benefit of improving the properties of the deasphalted oil compared to the bitumen, for example, by decreasing its...
