    摘要: The invention relates to an improved process for manufacturing an olefin polymer composition, in particular polyethylene, that incorporates two elongated tubular closed loop reaction zones (or the so-called “slurry loop” polymerization reactors) and a solids-concentrator in between the two reaction zones, that is optimally controlled to achieve the desired reactor and downstream solid concentrations required to make a range of polymer compositions including “bimodal” polymers where between-reactor hydrogen separation is important.
