ABSTRACT:
A system is provided for separating biomass from media in a fluidized bed reactor containing an aqueous suspension of biomass and media. A lift, configured to extend within the reactor, has an inlet for receiving aqueous suspension and an outlet spaced from the inlet for delivering the aqueous suspension from the lift. A shield is disposed about the lift. The system further includes a biomass separator body, including an inner member disposed about the shield and an outer member. Three annular passageways are defined between the lift, the shield, the inner member, and the outer member, and are positioned to receive aqueous suspension from each other. A barrier extends between the inner member and the outer member at an end portion of the third annular passageway. The barrier of the biomass separator body is configured to direct biomass from the third annular passageway toward an excess biomass discharge.
