LOOP REACTOR APPARATUS AND POLYMERIZATION PROCESSES WITH MULTIPLE FEED POINTS FOR OLEFINS AND CATALYSTS
摘要
A slurry polymerization process wherein olefin monomer is fed to a continuous loop reactor at two or more points, allowing operation at higher and steadier monomer concentrations in the circulating slurry. A loop reactor apparatus has two or more monomer feeds and may have two or more catalyst feeds and/or two or more product take-offs, and each feed may have its own associated control scheme.
