Abstract
Systems and methods for producing olefins and/or aromatics are disclosed. Methods disclosed includes aqua-processing hydro-processing of crude oils and/or heavy oils and/or residue, in an aqua-processing hydro-processing unit, to produce intermediate products, which can then be used to make valuable chemicals such as olefins and aromatics.
Claims20
A method of processing hydrocarbons, the method comprising:
- subjecting a mixture comprising (1) a feedstock of crude oil and/or heavy oil and/or residues, (2) steam, (3) hydrogen, (4) a catalyst, and (5) a solvent selective for dissolving asphaltene, in a processing unit, to conditions sufficient to convert at least some hydrocarbon molecules of the feedstock to molecules that have less carbon atoms than the at least some hydrocarbon molecules;
- recovering, from the processing unit, intermediate product streams comprising:
- (1) a gas stream that comprises primarily Ci to C4 hydrocarbons and (2) a liquid stream that comprises primarily saturates;
- and
- cracking the liquid stream to produce one or more of ethylene, propylene, butene, and benzene.
