  • Method and system for generating power from residual fuel oil
    Patent number: 5911875
    Abstract: 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.
