PROCESSES AND SYSTEMS FOR SOLVENT EXTRACTION OF BITUMEN FROM OIL SANDS |
摘要 |
Processes and systems are described for solvent extraction of bitumen from oil sands. Fines agglomeration is employed to simplify subsequent separation. A high quality bitumen product can be formed, which meets or exceeds downstream processing and pipeline requirements. An embodiment comprises combining a first solvent and a bituminous feed to form an initial slurry, which is optionally separated into fine solids and coarse solids. Slurry solids are agglomerated. A low solids bitumen extract from the agglomerated slurry is mixed with a second solvent having a similar or lower boiling point than the first. The mixture is separated, solvent recovered, and a high grade bitumen product is formed. Exemplary systems comprise a mixbox, agglomerator, separator unit with optional countercurrent washer and deep cone settler, and TSRU. Processes are provided for fractionating a hydrocarbon fluid into heavier and lighter fractions. The lighter fraction may be used in solvent extraction of bitumen.
