Abstract
Nickel and/or vanadium can be removed or transferred from a hydrocarbon phase to a water phase using an Extractant Composition selected from an isocyanate, a thiocyanate, a cyanides, mercaptides, nitrites, and mixtures thereof. The Extractant Composition may also include at least one mineral acid, a solvent, and other additives. The invention permits transfer of vanadium and nickel from a hydrocarbon into an aqueous phase with little or no hydrocarbon phase undercarry into the aqueous phase. The composition is particularly useful in treating crude oil.

A process for removing nickel and vanadium from a nickel and/or vanadium containing hydrocarbon (Hydrocarbon) comprising admixing the Hydrocarbon with an Extractant Composition and separating the Extractant Composition from the Hydrocarbon wherein some or substantially all of the nickel and/or vanadium is transferred from the Hydrocarbon to the Extractant Composition.
A process for removing nickel and vanadium from a nickel and/or vanadium containing hydrocarbon (Hydrocarbon) comprising admixing the Hydrocarbon with an Extractant Composition and separating the Extractant Composition from the Hydrocarbon wherein some or substantially all of the nickel and/or vanadium is transferred from the Hydrocarbon to the Extractant Composition and further comprising isolating the nickel and/or vanadium from the Extractant Composition.
