Process for treating hydrocarbons containing mercaptans

Patent ·
OSTI ID:7160163
This patent describes a process for treating hydrocarbon streams containing mercaptans. It comprises contacting a first mercaptan-containing hydrocarbon stream with a first aqueous alkaline solution stream to form a mercaptide-rich aqueous alkaline solution stream and a reduced-mercaptan hydrocarbon stream; combining the mercaptide-rich aqueous alkaline solution stream with a second mercaptan-containing hydrocarbon stream and with oxygen to form a first mixture; oxidizing the mixture to form a second mixture of hydrocarbon, disulfides and aqueous alkaline solution; and separating the second mixture into a disulfide-containing hydrocarbon stream and a regenerated aqueous alkaline solution stream.
