Abstract:
A process for producing polymer in a continuous slurry loop reactor comprising:reacting a monomer in a hydrocarbon diluent to form a polymerization slurry of polymer solids in a liquid medium; discharging a portion of the polymerization slurry as effluent which comprises a slurry of discharged polymer solids in a discharged liquid medium, through a discharge opening into a first transfer conduit; heating the effluent with a first heater; flashing the effluent in a first flash, wherein at least a portion of the discharged liquid medium is vaporized, to form a first flash vapor and a first flash slurry; condensing at least a portion of the first flash vapor without compression; discharging the first flash slurry from the first flash into a second transfer conduit; heating the first flash slurry with a second heater; and flashing the first flash slurry in a second flash.
