Beschreibung
Zusammenfassung:	A process for treating a bitumen froth comprising bitumen, solids and water to produce a deasphalted oil product is provided comprising optionally diluting the raw bitumen froth with a diluent to form a diluted bitumen froth; separating the raw or diluted bitumen froth into a light bitumen fraction and a heavy bitumen fraction comprising bitumen, fine solids and water; mixing the heavy bitumen fraction with a first solvent to form a solvent/bitumen mixture; and introducing the solvent/bitumen mixture into a first extraction vessel operating at a temperature and a pressure such that the solvent is at or near supercritical conditions to form a heavy phase comprising asphaltenes, solids and water and a light phase comprising deasphalted oil.
