  • Expansion of fuel streams using mixed hydrocarbons
    Patent number: 9388350
    Abstract: Methods and systems for blending multiple batches of mixed hydrocarbons into fuel streams downstream of the refinery are provided that do not compromise the octane value of the fuel and do not cause the volatility of the fuel to exceed volatilities imposed by government regulation.

  • METHODS FOR SPLITTING MIXED HYDROCARBON STREAMS
    Publication number: 20160137927
    Abstract: Methods of extracting and enriching high value pentane streams suitable for adding to refinery grade gasoline are provided by balancing the relative amounts of isopentane and n-pentane in the output stream of a depentanizer tower, and by balancing the sulfur fractions in the input and output streams of the tower.

  • LOW SULFUR MARINE FUEL
    Publication number: 20150353851
    Abstract: The invention pertains marine fuel compositions having a sulfur content of less than or equal to 1000 ppm and methods of producing the same. The low sulfur marine fuels are compliant for use in Sulfur Emission Control Areas beginning Jan. 1, 2015. The compositions comprise a blend of a residual fuel oil and a distillate fuel oil. The residual fuel oil can constitute from about 15% to about 50% by volume of the final blend and the distillate fuel oil from about 50% to about 85%. In some embodiments the residual fuel oil contains a vacuum tower bottoms component characterized by a flashpoint of 200 F or higher and the distillate fuel oil an ultra low sulfur diesel component characterized by a flashpoint of 120 F or higher. Methods of producing low sulfur marine fuel comprise blending a residual fuel oil with a distillate fuel oil.
