System and method for producing ultra-high molecular weight polyalphaolefins for use as pipeline drag reducing agents

A system for producing ultra-high molecular weight polymers comprising:

• a duplexed reactor shell comprising two reactor shells, each reactor shell comprising a plurality of hemispherical voids, the plurality of hemispherical voids connected by a plurality of conduits, such that when one reactor shell is fitted to another reactor shell to form the duplexed reactor shell, the plurality of hemispherical voids align to form a plurality of spherical reaction chambers connected by the plurality of conduits;
• a monomer inlet port connected to at least one spherical reaction chamber of the plurality of spherical reaction chambers, and a polymer outlet port connected to at least another spherical reaction chamber of the plurality of spherical reaction chambers, wherein the inlet ports convey a pressurized mixture of alpha-olefin monomer and catalyst into the plurality of spherical reaction chambers through the plurality of conduits to undergo polymerization;
• and
• a cooling vessel comprising at least one slot, wherein the slot receives the duplexed reactor shell and prevents the individual reactor shells from separating under pressure, wherein the cooling vessel contains a cooling fluid.
