Abstract

Process for the introduction of liquid feeds to a polymerization process, and in particular for the introduction of a fresh feed selected from fresh comonomer and fresh inert hydrocarbon to a polymerization reactor. The process includes passing the fresh feed and a process stream containing a first component selected from hydrogen, nitrogen and methane and a second component which is a monomer to a separator at a pressure of 0.4 MPa (4 bar) or less to produce a first stream containing the majority of the first component and a second stream containing the majority of the fresh feed and the majority of the second component, and passing the second stream to the polymerization reactor.
