ABSTRACT:
A monomer recycle process for fluid phase in-line blending of polymers is provided. In one form, the monomer recycle process includes providing a first group (G1) of one or more reactor trains and a second group (G2) of one or more reactor trains and one or more separators fluidly connected to G1 and one separator fluidly connected to G2; polymerizing in each reactor train of G1 and G2 olefin monomers to form homogenous fluid phase polymer-monomer mixtures wherein each of the G1 and G2 reactor trains have at least one common monomer; passing the reactor effluents from the one or more G1 reactor trains through the one or more G1 separators to separate a monomer-rich phase from a polymer-enriched phase; passing the polymer-enriched phase and the reactor effluents from the one or more G2 reactor trains into the G2 separator (separator-blender) to separate another monomer-rich phase from a polymer-rich blend; recycling to one or more G1 reactor trains the separated monomer-rich phase from the one or more G1 separators; and recycling to one or more G2 reactor trains the separated monomer-rich phase from the G2 separator. The polymer-rich blend is conveyed to a downstream finishing stage for further monomer stripping, drying and/or pelletizing to form a polymer product blend.
