Claim 0:
1. A method for creating a stable asphaltene containing residuum based marine fuel oil blend that meets International Marine Organization (IMO) fuel specifications, the method comprising:
in response to reception of an IMO fuel specification:
determining a first selection of one or more of an asphaltene containing residuum with an aromaticity of less than about 50% the first selection to thereby define one of a plurality of blend components;
determining a second selection of one or more of a high aromatic distillate, a hydrocarbon fraction, or a cracked stock with an aromaticity of greater than about 50%, the second selection to thereby define one of the plurality of blend components;
determining a third selection of one or more of an intermediate aromatic distillate, a hydrocarbon fraction, or a cracked stock with an aromaticity greater than the first selection and less than the second selection, the third selection to thereby define one of the plurality of blend components;
determining a sequence of addition for each one of a plurality of blend components into a blend tank to prevent asphaltene precipitation;
adding each one of the plurality of blend components to the blend tank at a specified time based on the sequence of addition until each of the one of the plurality of blend components have been added to the blend tank;
mixing each added blend component in the blend tank for a specified period of time prior to addition of a next one of the plurality blend components, each added blended component to thereby define a stable asphaltene containing residuum based marine fuel oil blend; and
providing the stable asphaltene containing residuum based marine fuel oil blend for use.
