Abstract
One exemplary embodiment can be a process for removing one or more disulfide compounds from a caustic stream. The process may include passing the caustic stream, previously contacted with a hydrocarbon stream for removing one or more thiol compounds, through a vessel containing a coalescing element to remove the one or more disulfide compounds downstream of a three-phase separator and a thiol oxidation zone.

A process for removing one or more disulfide compounds from a caustic stream, comprising:
- passing the caustic stream, previously contacted with a hydrocarbon stream for removing one or more thiol compounds, through a vessel containing a coalescing element to remove the one or more disulfide compounds downstream of a three-phase separator and a thiol oxidation zone.
A process for removing one or more disulfide compounds from a caustic stream, comprising:
- A) obtaining the caustic stream containing one or more thiol compounds from an extraction zone;
- B) passing the caustic stream to a thiol oxidation zone;
- C) obtaining an oxidized caustic stream and sending the stream to a three-phase separator;
- D) passing a separated caustic stream from the three-phase separator to a vessel containing a coalescing element to remove the one or more disulfide compounds;
- E) obtaining a disulfide stream from the vessel;
- and
- F) recycling the disulfide stream upstream of the thiol oxidation zone.

- D) passing a separated caustic stream from the three-phase separator to a vessel containing a coalescing element to remove the one or more disulfide compounds;
- E) obtaining a disulfide stream from the vessel;
- and
- F) recycling at least a portion of the disulfide stream to the vessel.
