Abstract

An apparatus and method for removing polymer solids from a slurry loop reactor. A discharge conduit having a longitudinal axis and an end section for removing polymer solids from the slurry loop reactor is provided. The discharge conduit is attached to the slurry loop reactor so that the longitudinal axis and at least a portion of an outer wall of the slurry loop reactor form an angle of less than about 90 degrees. The end section includes a first edge and a second edge that extends past at least a portion of an inner wall of the slurry loop reactor into a liquid reactor slurry. Polymer solids contained within the liquid reactor slurry are concentrated on the second edge so that an average polymer solids concentration in the discharge slurry is greater than an average polymer solids concentration of the liquid reactor slurry within the slurry loop reactor.
