Method for extracting bitumen from an oil sand stream |
摘要 |
The present invention provides a method for extracting bitumen from an oil sand stream, the method comprising at least the steps of, a) providing an oil sand stream; b) contacting the oil sand stream with a liquid comprising a solvent to obtain a solvent-diluted oil sand slurry; c) separating the oil sand slurry to obtain a first solids-depleted stream and a first solids-enriched stream; d) filtering the first solids-enriched stream obtained in step c) to obtain bitumen-depleted sand and at least a first filtrate; e) separating at least a part of the first filtrate to obtain a second solids-depleted stream and a second solids-enriched stream; and f) contacting at least a part of the second solids-enriched stream from step e) with solvent to obtain a solvent-diluted second solids-enriched stream; and g) separating the solvent-diluted second solids-enriched stream to obtain a third solids-enriched stream and a third solids-depleted stream. |

1. A method for extracting bitumen from an oil sand stream, the method comprising at least the steps of:
(a) providing an oil sand stream; (b) contacting the oil sand stream with a liquid comprising a solvent thereby obtaining a solvent-diluted oil sand slurry; (c) separating the solvent-diluted oil sand slurry, thereby obtaining a first solids-depleted stream and a first solids-enriched stream; (d) filtering the first solids-enriched stream obtained in step (c), thereby obtaining bitumen-depleted sand and at least a first filtrate; (e) separating at least a part of the first filtrate thereby obtaining a second solids-depleted stream and a second solids-enriched stream; and (f) contacting at least a part of the second solids-enriched stream as obtained in step (e) with solvent thereby obtaining a solvent-diluted second solids-enriched stream; and (g) separating the solvent-diluted second solids-enriched stream thereby obtaining a third solids-enriched stream and a third solids-depleted stream. |
