Abstract
A process is disclosed for producing very low sulfur content hydrocarbon streams by contacting a hydrocarbon feedstream with an aqueous alkaline treatment stream which has been regenerated by the biological conversion of sulfur compounds to elemental sulfur. The process is characterized by the step of contacting the partially regenerated aqueous treatment stream with a hydrocarbon wash stream to remove low levels of residual elemental sulfur suspended in the partially regenerated treatment stream.
