Patent ID: 7547750

Claim:
A slurry loop reactor comprising: (a) a discharge conduit having a longitudinal axis and an end section for removing a discharge slurry comprising polymer solids, the discharge slurry being withdrawn from a liquid reactor slurry contained within the slurry loop reactor, (b) a first edge of the end section of the discharge conduit that is substantially flush or recessed with an inner wall of the slurry loop reactor; and (c) a second edge of the end section of the discharge conduit that extends past at least a portion of the inner wall of the slurry loop reactor into the liquid reactor slurry so that the polymer solids are concentrated thereon and 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, wherein the second edge is elongated in relation to the first edge.
