Document Type and Number:
Japanese Patent JP2003516464
Kind Code:
A
Abstract:
A process for upgrading a hydrocarbon oil is provided which comprises introducing the oil and an aromatic extraction solvent containing 0.1 to 10 vol % water into an extraction zone for contact of the oil and solvent therein whereby an extract solution is formed; and injecting water into the extraction zone at a point below that at which the extraction solvent is introduced. The injected water is injected substantially countercurrent to the extraction solvent at a velocity of about 0.5 to 3 ft/sec in an amount ranging from about 0.1 to about 10 LV% based on the amount of extract solution being processed.
