Polymerization reactor

A novel chemical reactor; one particularly useful for the production of polymers, especially elastomers such as butyl rubber. The reactor (10) contains (1) a two-tube pass system, constituted of an inner or center tube bundle (20) through which a mixture or slurry of polymerizable monomers and catalyst is passed in one direction, and recycled via an outer tube bundle (30) in the opposite direction in essentially even flow distribution (2), while the tubes of the center and outer tubular bundles are maintained within a jacketed section, or sections of the reactor into which a coolant, or refrigerant; is injected and vaporized to remove the heat of reaction.

An even flow circulation of the slurry which aids in maintaining uniform low temperature, is provided by the use of (3) a diffuser (60) and (4) mixed flow pumping system (40), with its impeller (43), by virtue of which an adequate pressure head of even pressure profile is developed across the entry sides of the center tubes (20) to maintain the even flow distribution within the two-tube pass system at high circulation rate. There is no vortex whirl at the exit of the impeller-diffuser assembly, and no cavitation bubbles as commonly associated with one-tube pass systems, which employ a central draft tube and axial flow pump. Improved mixing, high hydraulic efficiency, and higher production rates with low polymer fouling, are achieved.
