A method of generating power from residual fuel oil that is deasphalted with a flow of process steam to produce a deasphalted oil stream, a pitch stream, and a deasphalting condensate stream. The deasphalted oil stream is burned in a pressurized oxygen-bearing gas to produce a pressurized hot gas stream. This pressurized hot gas stream is expanded in a turbine that produces shaft power and an expanded gas stream. The expanded gas stream is cooled by transferring heat from it to a flow of feed water that becomes steam. A portion of the steam becomes at least part of the flow of process steam used to deasphalt the residual fuel oil, thus integrating the deasphalting and the steam generation.

[ We claim:] [1.] A method for separating a vanadium containing residual fuel oil into a substantially vanadium free oil stream and into a vanadium containing pitch stream, and for generating power to fuel the separating process by combustion of at least one of the oil stream and pitch stream, comprising the steps of:a) deasphalting said residual fuel oil with a flow of process steam, to produce a deasphalted, substantially vanadium free oil stream, the pitch stream, and a deasphalting condensate stream;b) burning at least a portion of said deasphalted oil stream in a pressurized oxygen-bearing gas so as to produce a pressurized hot gas stream;c) expanding said pressurized hot gas stream in a first gas turbine so as to produce shaft power and an expanded gas stream;d) cooling said expanded gas stream by transferring heat from said expanded gas stream to a first flow of feed water, comprising at least a portion of said deasphalting condensate stream, so as to generate a first flow of generated steam, wherein said flow of process steam comprises at least a first portion of said first flow of generated steam; ande) expanding another portion of said generated steam in a steam turbine to produce shaft power.
