<p>The present invention is an apparatus and process for oxidizing mercaptans in a preferably kerosene stream. By using a catalyst promoter, sufficient separation of hydrocarbon and aqueous alkali occurs in the reactor vessel (54) to obviate the need for a settling tank. Hence, the sweetened kerosene can be withdrawn from the reactor vessel and sent directly to a residual alkali removal unit (94) such as a sand filter vessel or to a water wash vessel if jet grade fuel is desired. In an embodiment, the reactor vessel used for this purpose includes a reaction section (56) and a separation section (58) in the same reactor vessel and an aqueous alkali outlet (72) and a sweetened hydrocarbon outlet (66) in the separation section.</p> |
