POLYOLEFIN PRODUCTION WITH MULTIPLE POLYMERIZATION REACTORS

摘要

A polyolefin production system including: a first reactor configured to produce a first discharge slurry having a first polyolefin; a second reactor configured to produce a second discharge slurry having a second polyolefin; and a post-reactor treatment zone having at least a separation vessel configured to receive the second discharge slurry or both the first discharge slurry and the second discharge slurry.

1. A polyolefin production system comprising:
a first reactor configured to produce a first reactor discharge comprising a first polyolefin; a second reactor configured to produce a second reactor discharge comprising a second polyolefin; and a post-reactor treatment zone configured to receive the first reactor discharge and the second reactor discharge, wherein the first and second reactors are configured to allow the first reactor discharge to be (a) transferred to the second reactor and, alternatively, (b) diverted to by-pass the second reactor and fed into the post-reactor treatment zone wherein to the first and second polyolefins are first contacted in the post-reactor treatment zone, wherein the first polyolefin is 30 weight % to 70 weight % of the second polyolefin.
