Abstract: Embodiments of apparatuses and methods for conversion of mercaptans are provided. In one example, an apparatus comprises a vessel that is capable to receive a feed stream that comprises liquid hydrocarbons and the mercaptans. The vessel comprises a catalyst bed section that is capable of contacting the feed stream with a catalyst in the presence of oxygen (O2) and caustic at reaction conditions effective to oxidize the mercaptans and form a caustic-containing, sweetened liquid hydrocarbon-containing stream. A coalescing bed section is capable to coalesce and separate at least a portion of the caustic from the caustic-containing, sweetened liquid hydrocarbon-containing stream for forming a caustic-depleted, sweetened liquid hydrocarbon-containing product stream.

Abstract: Embodiments of apparatuses and methods for treating mercaptans are provided. In one example, an apparatus comprises a vessel capable of receiving a feed stream that comprises liquid hydrocarbons and the mercaptans. The vessel comprises an extraction section that is capable of extracting a portion of the mercaptans from the feed stream to form a mercaptan-reduced, liquid hydrocarbon-containing stream. A catalyst bed section is capable of contacting the mercaptan-reduced, liquid hydrocarbon-containing stream with a catalyst in the presence of oxygen (O2) and caustic at reaction conditions effective to oxidize a remaining portion of the mercaptans and form a sweetened liquid hydrocarbon-containing stream.

Abstract: One exemplary embodiment can be a process for purifying a disulfide oil. The process can include obtaining at least a portion of a disulfide oil coalesced from an alkaline stream, and passing the at least a portion of the disulfide oil through a mesh for recovering a purified disulfide oil stream.

Abstract: One exemplary embodiment can be a process for removing one or more sulfur-containing hydrocarbons. The process can include sending a stream including one or more alkaline compounds, one or more hydrocarbons, and one or more sulfur compounds to a stack of a disulfide separator, and sending a fluid downstream of a distributor to a vortex contacting device for providing a gas having no more than about 100 ppm, by weight, sulfur. Often, the stack includes one or more walls surrounding a void and the distributor positioned within the void, and is adapted to receive the stream having one or more phases.

Abstract: One exemplary embodiment can be a process for oxidizing one or more thiol compounds from an alkaline stream. The process may include passing a mixed stream having the alkaline stream to an oxidation vessel having a body and a neck. Often, the body contains one or more packing elements and the neck contains a packing, a distributor, and a mesh. The process can further include passing an oxidized alkaline stream to a separation vessel containing a first chamber and a second chamber. Usually, the first chamber contains a coated mesh.

Abstract: One exemplary embodiment can be a process for contacting an alkaline solution with kerosene or diesel. The process can include providing a stream of kerosene or diesel and at least one of a naphthenic acid and a salt thereof, with an additional alkaline solution to a prewash vessel, forming an emulsion interface between a kerosene or diesel phase and an alkaline phase in the prewash vessel, controlling an amount of the emulsion interface by withdrawing at least a portion of the emulsion interface between the two phases, and adding an acid to a withdrawn emulsion.
