Treatment of sour hydrocarbon distillate
An apparatus for use in sweetening a mercaptan-containing sour hydrocarbon distillate by the catalytic oxidation of the mercaptans therein to disulfides is described comprising: a vertical reaction vessel including a vertical conduit within the reaction vessel, the conduit having an upstream end and a downstream end; a fiber bundle secured within the conduit at the upstream end thereof and extending out the downstream end into a separation zone defined within the reaction vessel; a catalyst bed in annular arrangement about the conduit above the separation zone; means for introducing a first liquid caustic stream onto an upstream end of the fiber bundle; means for introducing the sour hydrocarbon distillate into the upstream end of the conduit; means for introducing a second liquid caustic stream into the catalyst bed; and means for removing the sweetened hydrocarbon distillate from the top of the catalyst bed.
