Abstract
Apparatus for the polymerization of an olefin in a particle form process to form solid particles of polyolefin in a liquid slurry in a polymerization zone and the solid polymer particles are separated from the liquid diluent and any unreacted monomer, in which a portion of the slurry is diverted in the polymerization zone through a liquid cyclone separator. This separator has a separating portion thereof in heat exchange relationship with the zone liquid. After the separation in the liquid cyclone the clarified separated liquid is returned continuously to the polymerization zone and the resulting concentrated slurry is directed to a place of separation of the polymer particles.
