Abstract
Processes for hydrotreating a hydrocarbon stream in which a separation zone and a stripping zone is disposed between two hydrotreating reactors. The stripping zone may comprise a portion of the second hydrotreating reactor. The separation zone may comprise two separator vessels. A separator vessel may include the scrubbing zone to receive a scrubbing fluid, for example, steam, hydrogen, or heated effluent, and remove HS and NH. A divided wall separator may be used. Vapor from the separator vessels can be recycled in the system.
