摘要

Apparatus and process for converting sulfur compounds in a hydrocarbon stream, and apparatus for contacting the hydrocarbon stream containing sulfur compounds with alkali. A process and a device are described for extracting sulfur compounds from a hydrocarbon stream.A section of pre washing to convert hydrogen sulfide in a sulfide salt by reaction with an alkali, so that the caustic communicates with an extraction section disposed directly above the pre wash section to convert mercaptans in mercaptu00eddeos by reau00e7u00e3 The alkali.The product of the hydrocarbon out of the section extraction through a aglomerador that prevent the alkali skirt with the stream of the product of hydrocarbon. A section of the pre wash for converting hydrogen sulfide to sodium sulfide by reaction with an alkali such as caustic solution, preparing the stream of hydrocarbon extraction.The alkali is continuously removed and regenerated spent alkali is continuously added to the pre washing.
