Abstract

The present invention relates to a process for preparing polyolefin in a polymerization loop reactor said loop reactor comprising: a plurality of interconnected pipes defining a flow path for a polyolefin slurry and one or more settling legs provided on at least one horizontal part of said interconnected pipes said process comprising the steps of: feeding olefin monomer liquid diluent polymerization catalyst optionally hydrogen and optionally olefin co monomer into said loop reactor; and polymerizing said olefin monomer and said optionally co monomer to produce said polyolefin slurry in said loop reactor; wherein the circulation velocity of the polyolefin slurry inside at least one horizontal part of said interconnected pipes provided with one or more settling legs is reduced by at least 20% and at most 60% compared to the circulation velocity inside the remainder of said loop reactor.
