Abstract

An apparatus for the treatment of a multiphase fluid, comprising a rotatable shaft having a fluid flow path coaxial with the shaft. A fixed guide member surrounds the shaft and comprises annular plural helical channels for imparting centrifugal forces to the fluid to concentrate heavier fluid into an outer annular flow path around an inner flow path for lighter fluid. An impeller is supported on and driven by the shaft. The flow in the outer flow path is diverted, so as to divert the flow of the fluid of greater specific gravity into an annular channel member having an impeller. A stationary scoop extracts fluid from the channel member. The impeller comprises generally radially outwardly extending disks receiving fluid flowing on the inner flow path between them. Guide vanes are carried by the disks for guiding the fluid radially outwardly. A discharge chamber in the form of a volute is provided for the lighter fluid on the inner flow path issuing from between the disks.
