Process for removing metals from crude
First Claim
1. A process for removing metal from a metal-containing hydrocarbon oil which comprises:
- (a) contacting a hydrocarbon oil phase containing at least one metal selected from the group consisting of vanadium and nickel with an aqueous phase of dissolved phosphorous compound capable of forming a compound or a complex with said metal, said aqueous phase containing from about 0.1 to about 20 parts by weight of water per part by weight of hydrocarbon oil contacted therewith, said contacting resulting in the removal of a substantial quantity of the metal from the hydrocarbon oil phase to the aqueous phase; and
,(b) separating the metal-containing aqueous phase from the demetalated hydrocarbon oil phase prior to subjecting the latter to downstream catalytic processing.

Abstract
A process for removing metal from a metal-containing hydrocarbon oil such as a heavy crude is disclosed which comprises:
(a) contacting a hydrocarbon oil phase containing at least one metal selected from the group consisting of vanadium and nickel with an aqueous phase of dissolved phosphorous compound capable of forming a compound or a complex with said metal, said aqueous phase containing a substantial quantity of water relative to the amount of liquid hydrocarbon contacted therewith, said contacting resulting in the removal of a substantial quantity of the metal from the hydrocarbon oil phase to the aqueous phase; and,
(b) separating the metal-containing aqueous phase from the demetalated hydrocarbon oil phase prior to subjecting the latter to downstream catalytic processing.
