    摘要: Polymerization process including polymerizing a monomer and a comonomer in a polymerization reaction, withdrawing an effluent stream containing solid polymer and a mixture of unreacted monomer and unreacted comonomer, and passing the effluent to a high pressure recovery system having (a) a high pressure separation step for separating vapor containing unreacted monomer and unreacted comonomer from the solids, and (b) a high pressure recycle system for recycling a portion of the vapor to the polymerization reaction, passing the solids from the high pressure recovery system to a low pressure recovery system having (a) a low pressure separation step for separating further unreacted monomer and unreacted comonomer from the solids, and (b) a low pressure recycle system for recycling at least a portion of the unreacted monomer and unreacted comonomer to the polymerization reaction. A portion of the vapor separated in step 2(a) is passed to the low pressure recovery system.

    摘要: 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.

    摘要: Process for introducing a fresh feed of fresh comonomer and/or fresh inert hydrocarbon to a polymerization reactor which is part of a polymerization process having high and low pressure recovery systems, the high pressure recovery system being at a pressure of 0.5 MPa (5 bar) or above and the low pressure recovery system being at a pressure of less than 0.5 MPa (5 bar). The process includes passing the fresh feed and a process stream containing a first component of hydrogen, nitrogen and/or methane and a second component of a monomer to a separator which is part of the low pressure recovery system and is at a pressure of 0.4 MPa or less to produce a first stream containing a majority of the first component and a second stream containing the second component and a majority of the fresh feed, and passing the second stream to the polymerization reactor.
