US 11,377,604 B2 · Fuel compositions from light tight oils and high sulfur fuel oils

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.

Dependent claims

A fuel derived from combining

(a) light tight oil and
(b) hydroconversion reaction effluent comprising treated soluble deasphalted oil and lighter materials derived from hydroconversion of high sulfur fuel oil, or other residuals processed by residue hydroconversion to form said effluent comprising treated liquids and unconverted oils,
(1) said unconverted oils passed to solvent separation to remove insoluble remaining metals and asphaltenes to form soluble deasphalted oil, and
(2) said soluble deasphalted oil subsequent treated either by additional hydrotreating or additional hydroconversion to form said treated soluble deasphalted oil,
said fuel having
(i) an actual sulfur content of 0.5 wt. % or less, and
(ii) initial boiling point being that of lowest boiling component of light tight oil or lighter materials from said hydroconversion so combined and
(iii) highest boiling point being that of highest boiling component of said treated soluble deasphalted oil derived from high sulfur fuel oil or other residuals so combined.

5 more elements

A fuel derived from light tight oil and high sulfur fuel oil, either alone or with crude oil, said fuel having an actual sulfur content of 0.5 wt. % or less, and characterized by:

(a) highest boiling point being that of a highest boiling portion of effluent from a solvent separation of a hydroconverted high sulfur fuel oil or of a hydroconverted vacuum residual of high sulfur fuel oil, either alone or with crude oil, which effluent is subsequently treated by either by hydroconversion alone or hydroconversion followed by hydrotreating, and combined to form a portion of said fuel, and
(b) an initial boiling point being that of a lowest boiling point hydrocarbon within:
(i) directly combined light tight oil combined in said fuel, or
(ii) fractionated light tight oil combined in said fuel, or
(iii) a lightest component from said effluent of (a) combined in said fuel, wherein said 5.(b)(i) or (ii) is not treated by hydrogen in presence of catalyst.
