Abstract
A process is presented for the removal of contaminants like oxygenates from hydrocarbons. The contaminant oxygenates are removed from hydrocarbons that may be feed to cracking units. A crude feed stream is fed to a water wash column along with water to remove oxygenates and is subsequently treated with an adsorbent to effectively remove all the oxygenates from the crude hydrocarbon. A regenerant medium from a naphtha hydrotreating unit is used to regenerate the adsorbent.
Claims18
A process for removing contaminants from hydrocarbon streams comprising:
- splitting a hydrocarbon feed stream into a light hydrocarbon stream and a splitter bottoms hydrocarbon stream;
- contacting the splitter bottoms hydrocarbon stream with an adsorbent at first operating conditions to remove a portion of at least one contaminant to produce an effluent stream;
- and
- taking a slip stream from a naphtha stripper bottoms hydrocarbon stream to regenerate the adsorbent.
A process for removing contaminants from hydrocarbon streams comprising:
- splitting a hydrocarbon feed stream into a light hydrocarbon stream and a splitter bottoms hydrocarbon stream;
- contacting the splitter bottoms hydrocarbon stream with an adsorbent at first operating conditions to remove a portion of at least one contaminant to produce an effluent stream;
- contacting a light hydrocarbon stream from overhead of a naphtha splitter with the adsorbent to regenerate the adsorbent;
- and
- wherein the hydrocarbon feed stream comprises crude naphtha.

- splitting a hydrocarbon feed stream into a light hydrocarbon stream and a splitter bottoms hydrocarbon stream;
- contacting the splitter bottoms hydrocarbon stream with an adsorbent at first operating conditions to remove a portion of at least one contaminant to produce an effluent stream;
- contacting a syn gas stream with the adsorbent to regenerate the adsorbent;
