Sorption vessel with internal interstage screening vessel

摘要

A sorption vessel including a tank for retaining a pulp of an aqueous slurry and a sorbent at a predetermined liquid pulp level therein; and an interstage screening system disposed within the tank and at least partially submerged beneath the predetermined pulp level. The interstage screening system includes a housing for isolating the system from the pulp, thereby providing a hydraulic differential between the predetermined pulp level and the screening system; a conduit for selectively introducing the pulp onto the screen member, the pulp being urged through the conduit by the hydraulic differential; and at least one screen member disposed within the housing for selectively and continuously separating the sorbent from the pulp.
