Loop polymerisation reactor

摘要

The invention relates to a process for producing polymer in a continuous slurry loop reactor comprising reacting a monomer in a hydrocarbon diluent to form a polymerization slurry ofpolymer solids in a liquid medium, discharging a portion of the polymerization slurry as slurry effluent which comprises a slurry of discharged polymer solids in a discharged liquid medium through at least two discharge conduits (504A and 504B), combining the effluent from at least two of the discharge conduits, flashing the combined effluent in a first flash (11) to form a first flash vapor and a first flash slurry, and condensing at least a portion of the first flash vapor without compression.
