Abstract
A reaction system and method for removing heteroatoms from oxidized-heteroatom-containing hydrocarbon streams and products derived therefrom are disclosed. An oxidized-heteroatom-containing hydrocarbon feed is reacted in a reaction system thereby forming non-ionic hydrocarbon products. The products derived therefrom are useful as transportation fuels, lubricants, refinery intermediates, or refinery feeds.
Claims18
A reaction method for reducing a heteroatom content, reducing a total acid number, and increasing API gravity of an oxidized-heteroatom-containing hydrocarbon feed stream comprising:
- providing an oxidized-heteroatom-containing hydrocarbon feed stream through a first feed inlet region;
- providing a caustic and selectivity promoter stream, wherein the selectivity promoter stream includes an alcohol, a polyol, or mixtures thereof;
- providing a contact region receiving the oxidized heteroatom-containing hydrocarbon feed stream from the first inlet region and the caustic and the selectivity promoter stream from a second inlet region;
- contacting the oxidized-heteroatom-containing hydrocarbon feed stream with the caustic and selectivity promoter stream in the contact region thereby producing a substantially non-ionic hydrocarbon product having a reduced concentration of oxidized-heteroatom compounds than the oxidized-heteroatom-containing hydrocarbon feed stream that entered through the first feed inlet region;
- and
- removing the substantially non-ionic hydrocarbon products from the contact region.
A reaction method for reducing a heteroatom content, reducing a total acid number, and increasing API gravity of an oxidized-heteroatom-containing hydrocarbon feed stream comprising the steps of:
- providing an oxidized-heteroatom-containing hydrocarbon feed stream through a feed inlet region;
- providing a contact region, the contact region having at least one caustic and at least one selectivity promoter operatively positioned therein;
- contacting the oxidized-heteroatom-containing hydrocarbon feed stream in the contact region thereby producing a substantially non-ionic hydrocarbon product having a heteroatom content less than the oxidized-heteroatom-containing hydrocarbon feed stream that entered through the feed inlet region and a sulfate salt;
- removing the substantially non-ionic hydrocarbon product having a heteroatom content less than the oxidized-heteroatom-containing hydrocarbon feed stream that entered through the feed inlet region from the contact region through a first outlet region;
- and
- removing the caustic, selectivity promoter and sulfate salt from the contact region through a second outlet region.
