摘要

"APPARATUS AND PROCESS FOR EXTRACTiNG SULFUR COMPOUNDS FROM A HYDROCARBON STREAM" 5 A process for converting sulfur compounds in a hydrocarbon stream comprising: mixing a hydrocarbon stream and an alkaline stream; feeding said hydrocarbon stream mixed with said alkaline stream to a prewash section containing alkali to convert hydrogen sulfide to a sulfide salt; continuously withdrawing a spent alkaline stream containing sulfides from said prewash section; recirculating at least part of said spent alkaline steam to be mixed with said 10 hydrocarbon stream; continuously adding a regenerated alkaline stream to said prewash section; withdrawing a prewashed hydrocarbon stream from said prewash section; and feeding said prewashed hydrocarbon stream to an extractor section discrete from said prewash section, said extractor section containing alkali. owo 0) 5((9 'I rr-
