| titleOfInvention | Process for deasphalting bitumen |
| abstract | A process for upgrading heavy oil and bitumen includes deasphalting the bitumen by de-watering the bitumen/water emulsion to a water concentration of from about 0 to about 20% by volume. A surfactant is added to the de-watered bitumen/water emulsion to form a stable asphaltene-in-water emulsion as a separate phase from the deasphalted bitumen. The surfactant is preferably non-ionic and, more preferably, an ethoxylated alkyl phenol. In accordance with the present invention, the viscosity of the bitumen is significantly reduced and the quality of the bitumen is improved. The asphaltene is recovered in a useable form which can be used as a source of fuel at the production site and which additionally can be used to enhance the recovery of the bitumen from the rock formation. |
