Fuel compositions from light tight oils and high sulfur fuel oils
First Claim
1. A formulated combination useful as a fuel characterized in that said fuel is formed by combining a range of hydrocarbons constituents of (L)+(M)+(H) and the resulting combination is determined, based on 100 volume percent total, as follows:
- (a) (L) %+(M) %+(H) %=100% and(b) (L) %=(H) %=(100%−
(M) %)/2) and(c) if (M) % is zero or otherwise less than 100%, the remainder is (L) %/(H) % in ratio of 0.4/1 to 0.6/1,(d) wherein such combination has final (1) combination density within 820 to 880 Kg/M3 at 15°
C., (2) sulfur content of 0.5 wt. % or less and (3) metals content of 40 ppmwt or less, except if (M) % is zero or otherwise less than 100% and the remainder is (L) %/(H) % in ratio of 0.4/1 to 0.6/1, then sulfur content is 0.25 wt. % or less,(e) wherein (L) comprises components of naphtha and kerosene range materials, which are refined or partially refined, unrefined or extracted and used without being subject to any fractionation, hydrotreating or other treatment process, except optional separation of light gases or water, having an initial boiling point of 38°
C. (100°
F.) or less having a ninety percent (90%) plus final boiling point of 190°
C. (374°
F.) to about 205°
C. (401°
F.), where (L) range components contribute to (L) range bulk density and to final combination density even though individual constituents of (L) may fall outside said combination density range,(f) wherein (M) comprises refined or partially refined petroleum fractions having initial boiling point of about 190°
C. (374°
F.) to about 205°
C. (401°
F.) and a 90% plus final boiling point of about 385°
C. (725°
F.) to 410°
C. (770°
F.), where (M) range components contribute to (M) range bulk density and to final combination density, even though individual constituents of (M) may fall outside said combination density range, and(g) wherein (H) comprises refined or partially refined petroleum fractions having initial boiling point of about 385°
C. (725°
F.) to about 410°
C. (770°
F.) and a final boiling point of about 815°
C. (1499°
F.) or less, where final boiling point of (H) is highest boiling point of a component of a stream treated by solvent separation to reduce presence of asphaltenes and metals then recovered and subsequently treated by hydroconversion or hydrotreating to a level to enable addition of such stream to a combination of (L), (M) and (H) to meet final sulfur content for the combination fuel, and where (H) range components contribute to (H) range bulk density and to final combination density even though individual constituents of (H) may fall outside said combination density range.

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.
