摘要：A method and arrangement of producing polymer comprising polymerizing in

reactor having a top zone having a generally conical shape, a middle zone in directcontact with and below said top zone having a generally cylindrical shape, a bottom zonehaving a generally conical shape thereby polymerizing at least one olefin, in the presenceof a polymerization catalyst and fluidization gas to obtain (iv) a first stream comprisingfluidization gas and particles of olefin polymer, (v) a second stream comprising

fluidization gas and agglomerates of olefin polymer, (vi) a third olefin polymer productstream, - directing the first stream comprising fluidization gas and olefin polymerparticles to a series of at least three cyclones connected to the fluidized bed reactor, -separating agglomerates of olefin polymer from the second stream, withdrawing fromthe fluidized bed polymerization reactor the third olefin polymer product stream.
