Title: FLOW IN A SLURRY LOOP REACTOR
Abstract:
Olefin polymerization processes are described herein. The processes generally include circulating a slurry including an olefin monomer selected from C2-C12 olefin monomers, a liquid diluent selected from C3-C7 alkanes, catalyst and polyolefin particles under polymerization conditions within a loop reactor. In one or more specific embodiments, in operation, the process has a cavitation number of from 6 to 60 and the polymerization conditions include a polymerization temperature of from 38°C to 121°C and a polymerization pressure of from 27 bar to 50 bar. In other embodiments, the process has a Euler Number (Eu) of at least (5).
