摘要:
One exemplary embodiment can be an apparatus for treating a hydrocarbon stream having one or more compounds with a boiling point of about 140° to about 450° C. The apparatus can include an extraction zone and a regeneration zone. The extraction zone can include at least one settler. Each settler can have a height and a length. Typically the length is greater than the height. Also, the settler can form a boot, which can be adapted to receive a feed at one end. The regeneration zone may include a regenerator for an ionic liquid. The regenerator can include a column adapted to provide a regenerated ionic liquid to the extraction zone.

摘要:
A novel liquid collector assembly has been developed for a reactor used in the sweetening of sour hydrocarbons (e.g. sour gasoline). This refinery process normally involves contacting a reaction liquid, comprising both aqueous (caustic solution) and organic (hydrocarbon) phases, with a fixed bed of oxidation catalyst. The collector assembly design, comprising a piping manifold and a plurality of dependent, vertically aligned, and perforated conduits, allows for improved separation of the reaction products into essentially pure treated hydrocarbon and spent alkaline reagent streams. If sodium hydroxide is used as caustic solution, for example, the treated hydrocarbon product will normally contain less than 1 ppm by weight of sodium.

Disclosed is an apparatus for extracting sulfur compounds from a hydrocarbon stream. A prewash section for converting hydrogen sulfide to sodium sulfide by reaction with an alkali such as caustic prepares the hydrocarbon stream for extraction. Spent alkali is continuously withdrawn and regenerated alkali is continuously added to the prewash section.

摘要:
Described is an apparatus and process for extracting sulfur compounds from a hydrocarbon stream. A prewash section for converting hydrogen sulfide to sodium sulfide by reaction with an alkali such as caustic communicates with an extractor section disposed directly above the prewash section for converting mercaptans to mercaptides by reaction with alkali. Hydrocarbon product exits the extractor section through a coalescer that prevents alkali from exiting with the hydrocarbon product stream.

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.
