Loop reactor suitable for olefin polymerization with improved product removal means

Multiple loop reactors adapted for olefin polymerization comprising at least two loop reactors, whereby a first and second loop reactors are connected in series via a single settling leg of the first reactor, wherein said single settling leg is connected to said first loop reactor through a take off line extending from said first reactor to said settling leg and configured to remove said polymer slurry from said reactor, and a return line extending from said settling leg to said first reactor, wherein said take off line is radially connected to said single settling leg.

Multiple loop reactors adaptable for olefin polymerization comprising:

• at least a first loop reactor comprising a plurality of interconnected pipes defining a flow path for a polymer slurry, said slurry consisting essentially of an olefin reactant, a polymerization catalyst, liquid diluent and solid olefin polymer particles, means for introducing olefin reactant, polymerization catalyst and diluent into said reactor, a pump suitable for maintaining the polymer slurry in circulation in said reactor, and one or more settling legs connected to said first reactor, at least a second loop reactor comprising a single settling leg connected to said second loop reactor through a take off line extending from said second reactor to said settling leg and configured to remove said polymer slurry from said reactor, and a return line extending from said settling leg to said second reactor, wherein said take off line is radially connected to said single settling leg, whereby said first and second loop reactors are connected in series via one or more settling legs of the first loop reactor.
