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 (16)

1. A liquid fuel characterized by components of feed oil from which said fuel is formed, said fuel comprising

(a) untreated liquid fractions at or below sulfur breakpoint of said feed oil,

(b) hydrotreated liquid fractions over sulfur breakpoint of said feed oil, wherein said fuel

(1) comprises hydroconverted solubles over sulfur breakpoint of said feed oil and

(2) excludes hydroconverted fractions insoluble in one or more solvents used for solvent separation, and

(3) wherein highest boiling point of said fuel is the highest boiling point of said hydroconverted solubles.

2. A fuel of claim 1 wherein said feed oil comprises crude oil, either alone or combined with high sulfur fuel oil, vacuum residual oil or residual oils heavier than vacuum residual oil.

3. A fuel of claim 1 wherein said feed oil comprises light tight oil selected from the group consisting of one or more of well head condensate, non- associated natural gas condensates, shale gas condensate or other light crude.

4. A fuel of claim 1 wherein said feed oil comprises light tight oil having a sulfur content in the ranges of 0.1 wt. % to 0.2 wt. % and a density, API (Deg) in the range of 38 to 57 and distillation cut fraction ranges, in weight percent of mass, of (a) 5 to 20 wt. % liquefied petroleum gas range, (b) 10 to 35 wt. % naphtha, (c) 15 to 30 wt. % kerosene, (d) 15 to 25% diesel, (e) vacuum gas oils and (f) no (0%) to 10% heavy residuals.

5. A fuel of claim 1 comprising a combination of hydrocarbons ranging from

(a) lowest boiling point being that of low boiling portion of an untreated liquid fraction combined in said fuel to

(b) highest boiling highest boiling point being that of highest boiling soluble hydroconverted fraction over sulfur breakpoint combined in said fuel,

wherein said highest boiling soluble is soluble in one or more liquid solvents used for solvent separation.

6. A fuel of claim 1 having an initial boiling point in the range about 35° C. to about 315° C. and higher up to a maximum boiling point being the initial boiling point of soluble deasphalted oil within said fuel.

7. A fuel of claim 1 having a target sulfur content of 0.5 wt. % or less.

8. A fuel of claim 1 comprising a first hydrotreated stream which is a reduced sulfur stream having a sulfur content less than 10 ppmwt of sulfur, and a second hydrotreated fuel fractions which is a reduced sulfur stream having a sulfur content in the range of 0.12 to 0.18 wt. % sulfur.
