Patent ID: 8192689

Claim:
A system for the recovery of a polymer sample from a polymerization reactor comprising: a polymerization reactor for the polymerization of an olefin monomer in a liquid diluent to form an olefin polymer; a sample conduit connected to said polymerization reactor for receiving a sample of polymer particles in said liquid diluent from said polymerization reactor; a sample release valve disposed in said conduit; an automatic flushing mechanism in fluid connection with the sample conduit; a flash tank operably connected to said conduit effective for the separation of said diluent from polymer particles and comprising an inlet connected through a flash line to the outlet of said sample release valve, a first outlet for the removal of polymer particles from said flash tank and a second outlet for the release of gas from said flash tank; a sample receiving chamber having an inlet for receiving the polymer sample and an analyzer; and a sample transfer line extending from said flash vessel to said sample receiving chamber and provided with at least one valve with the outlet of said valve connected to said sample receiving chamber.
