Patent ID: 6844401

Claim:
A method for olefin polymerization comprising: providing a reactor system including a plurality of reactors arranged for parallel flow, each said reactor defining an internal reaction zone; supplying an olefin containing feedstock and dividing the same into a plurality of separate feedstock streams; introducing each of said separate olefin containing feedstock streams into the reaction zone of a respective one of said reactors; conducting an exothermic olefin polymerization reaction on an olefin polymerization reaction mixture in each reaction zone; separately circulating the reaction mixture in each reactor at a flow rate that is independent of the rate of introduction of the respective stream of feedstock into the reaction zone while said exothermic olefin polymerization reaction is ongoing; removing a crude polyolefin product stream from each of said reactors; and combining said crude polyolefin product streams to form a single crude product stream.
