More Information
Summary:The invention relates to naphtha hydrodesulfurization incorporating either high temperature depressurization or controlled heating for mercaptan removal. More particularly, the invention relates to a naphtha hydrodesulfurization process, wherein the hot naphtha exiting the desulfurization reactor (12) contains mercaptans, most of which are removed without olefin loss, by depressurizing the hot naphtha (14), thermally treating the hot naphtha, or some combination thereof. The desulfurized naphtha may be cooled and condensed to a liquid, separated (16) from the gaseous H2S, stripped and sent to a mogas pool.
