摘要： A reactor system containing one or more loop reactors for olefin polymerization is provided. The loop reactors include vertical sections, elbow sections, and/or horizontal sections connected into one or more loop reaction zones to polymerize an olefin monomer in the presence of a liquid diluent into a slurry comprising particles of a polyolefin polymer. The reactor system footprint is reduced to increase production efficiency and save cost, while maintaining a high processing capacity. In one embodiment a horizontal length (L H ) of at least one horizontal section is greatly reduced with maintained processing capacity. In another embodiment, at least one elbow section of the reactor system is configured to maintain a Dean number (D n ) of the slurry flowing therein to be higher than 3,000,000.
