摘要：
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 Spent alkali is continuously withdrawn and regenerated alkali is continuously added to the prewash section.
