Abstract
For the shipping industry, these fuels provide solutions to long outstanding technical problems that heretofore hindered supply of low sulfur marine fuels in quantities needed to meet worldwide sulfur reduction goals. When ships on the open seas burn cheap low grade heavy bunker oils high in sulfur, nitrogen and metals, the SOx, NOx, and metal oxides go to the environment. This invention converts essentially all of each barrel of crude feed to a single ultraclean fuel versus conventional refining where crude feed is cut into many pieces, and each piece is sent down a separate market path meeting various different product specifications. When in port, ships can generate and sell electricity to land based electrical grids to offset fuel cost in an environment-friendly manner.
Claims1
A fuel characterized in that the highest boiling point of said fuel is the highest boiling portion of effluent from solvent separation which is subsequently treated by hydrogen and forms a portion of said fuel, wherein said fuel has further comprises components of a blend of light tight oil with hydroprocessed high sulfur fuel oil or other heavy residual, and said fuel has a sulfur content in range of 0.05 m/m (wt. %) to 0.5 m/m (wt. %).
