Abstract

Methods are provided to prepare a low sulfur fuel from hydrocarbon sources, such as light tight oil and high sulfur fuel oil, often less desired by conventional refiners, who split crude into a wide range of differing products and may prefer presence of wide ranges (C3 or C5 to C20 or higher) of hydrocarbons. These fuels can be produced by separating feeds into untreated and treated streams, and then recombining them. Such fuels can also be formulated by combinations of light, middle and heavy range constituents in a selected manner as claimed. Not only low in sulfur, the fuels of this invention are also low in nitrogen and essentially metals free. Fuel use applications include on-board large marine transport vessels but also on-shore for large land based combustion gas turbines, boilers, fired heaters and transport vehicles and trains.

Claims (13)

1. A fuel characterized in that said fuel comprises components from feeds

(i) of one or more light tight oil selected from group consisting of well head condensate, non-associated natural gas condensates, or shale gas condensate and

(ii) of high sulfur fuel oil, said fuel further comprising:

(a) one or more non-hydrotreated components selected from group consisting of components from

(1) non-hydrotreated unstabilized wild straight run naphtha and

(2) non-hydrotreated distillation fractions of said feeds

(i) of light tight oil and

(ii) of high sulfur fuel oil,

wherein said (a)(1) non-hydrotreated naphtha and said (a)( (2) non-hydrotreated distillation fractions of said feeds of (i) light tight oil and of (ii) high sulfur fuel oil are characterized in that sulfur content of all components of said) (a)(1) non-hydrotreated naphtha and (a)(2) said non-hydrotreated distillation fractions are at or below sulfur breakpoint cut of said feeds of (i) light tight oil and of (ii) high sulfur fuel oil, and all said components of (a) are combined in said fuel without treatment by hydrogen, and

(b) one or more hydrotreated components from hydrotreated distillation fractions above sulfur breakpoint cut selected from group consisting of

(1) hydrotreated wild naphtha above sulfur breakpoint cut,

(2) hydrotreated heavy oil range distillation fraction and

(3) hydroconverted oils comprising hydroconverted high sulfur fuel oil.
