Abstract

The liquid content of granular product removed from a fluidized bed polymerization reactor operating in the condensing mode is reduced or minimized by removing the product from a level in the fluidized bed which is about 0.21 to about 0.59 of its height while venting the product discharge tank to a point higher in the fluidized bed.
