Apparatus and method for removing polymer solids from slurry loop reactor

A process for discharging a discharge slurry from a slurry loop reactor comprising the steps of:

• (a) opening a discharge conduit to the slurry loop reactor, the discharge conduit having a longitudinal axis and an end section for removing the discharge slurry comprising polymer solids from the slurry loop reactor, the end section comprising 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 contained within the slurry loop reactor, wherein the second edge is elongated in relation to the first edge:
• (b) concentrating the polymer solids on the second edge of the end section so that an average polymer solids concentration in the discharge slurry is greater than an avenge polymer solids concentration in the liquid reactor slurry;
• and
• (c) discharging the concentrated polymer solids through the discharge conduit as part of the discharge slurry so that an average polymer solids concentration in the discharge slurry is greater than an average polymer solids concentration in the liquid reactor slurry.
