Processes and apparatuses are disclosed for treating a naphtha stream from a FCC unit comprising passing the naphtha stream to a naphtha splitter column to provide a light naphtha stream and a heavy naphtha stream. The light naphtha stream is reacted in a mercaptan oxidation reactor to provide a demercaptanized naphtha stream. The demercaptanized naphtha stream is stripped in a light stripper column to provide a treated light naphtha stream and a bottoms stream.
