ABSTRACT:
A process for the treatment of light naphtha hydrocarbon streams is disclosed wherein the mercaptans contained therein are reacted with diolefins simultaneous with fractionation into a light stream and a heavy stream. The heavy stream is then simultaneously treated at high temperatures and low pressures and fractionated. The naphtha is then stripped of the hydrogen sulfide in a final stripper.
