A process for upgrading a hydrocarbon feed, such as crude oil or other heavy oils, may include hydrotreating a hydrocarbon feed in a hydrotreating unit to produce a hydrotreated effluent that includes asphaltenes, coke precursors, or both. The process further includes hydrocracking the hydrotreated effluent in a hydrocracking unit to produce a hydrocracked effluent, adsorbing at least a portion of the asphaltenes, coke precursors, or both, from the hydrotreated effluent, the hydrocracked effluent, or both, separating the hydrocracked effluent into at least an upgraded lesser-boiling effluent and a greater-boiling effluent in a hydrocracked effluent separation system, and steam cracking the upgraded lesser-boiling effluent to produce olefins, aromatic compounds, or combinations of these. The process may further include recycling the greater boiling effluent back to the hydrotreating unit and hydrocracking a middle distillate effluent from the hydrocracked effluent separation system. Systems for conducting the processes are also disclosed.

Conversion of crude oil to aromatic and olefinic petrochemicals

Methods of extracting 1-4 cycle heterocyclic compounds and 2-5 cycle polynuclear aromatic hydrocarbons from a hydrocarbon feedstock are described. The methods include providing a hydrocarbon feedstock containing crude oil fractions, and determining an A/R ratio and an asphaltene concentration of the hydrocarbon feedstock. Based upon the A/R ratio and the asphaltene concentration, the treatable hydrocarbon feedstock undergoes one or more of cracking and fractionating. Subsequently, at least one targeted portion of the heterocyclic compounds is extracted from the fractionated stream with an aqueous solvent. A stream containing the 2-5 cycle polynuclear aromatic hydrocarbons is transferred to an extractor and the 2-5 cycle polynuclear aromatic hydrocarbons are extracted with a solvent system comprising an aprotic solvent.

A method for co-processing HS and COin an electrolyzer includes feeding a first gas stream having HS to an anode and feeding a second gas stream having COto a cathode. The HS is split into hydrogen and elemental sulfur. The hydrogen is transferred from the anode to the cathode, and the COis hydrogenated with the transferred hydrogen. A method for producing electricity in a fuel cell includes feeding a first gas stream having HS and CO to an anode, and feeding a second gas stream having oxygen to a cathode. The HS and CO forms hydrogen and carbonyl sulfide. The hydrogen is transferred from the anode to the cathode. The transferred hydrogen is oxidized with the oxygen of the second gas stream, and electricity formed from the oxidation is collected.

Methods for co-processing carbon dioxide and hydrogen sulfide

Methods are provided for extracting heterocyclic compounds, organometallic compounds, and polynuclear aromatic hydrocarbons from a hydrocarbon feedstock such as crude oil or a crude fraction. The heterocyclic compounds and organometallic compounds are removed from the hydrocarbon feedstock through one or more successive extractions to form a first raffinate. The extractions use a first solvent system containing an ionic liquid formed from carbon dioxide and water. The polynuclear aromatic hydrocarbons are removed from the first raffinate using a second solvent system containing an aprotic solvent such as NMP, DMSO, aromatics, or combinations thereof. The extracted compounds remain chemically intact and may be fractionated for further applications. Further methods are provided for producing a hydrocarbon raffinate having reduced levels of heterocyclic compounds, organometallic compounds, and 2-4 cycle polynuclear aromatic hydrocarbons.
