1. A method for treating a spent caustic stream comprising:
providing a source of the spent caustic stream; reducing a pH of a first portion of the spent caustic stream to provide an acidified stream; introducing a first portion of the acidified stream to a first inlet of a first vessel comprising adsorbent media to provide a polished stream; and introducing a second portion of the spent caustic stream to a second inlet of the first vessel to regenerate the adsorbent media in the first vessel.
