System and method for monitoring and controlling a polymerization system

A polymerization system, comprising:

• a reactor system comprising a polymerization reactor;
• a feed system fluidly coupled to a feed inlet of the polymerization reactor, wherein the feed system is configured to supply polymerization components comprising a monomer, a comonomer, a catalyst, and a diluent to the polymerization reactor via the feed inlet, and the polymerization reactor comprises a flow path configured to continuously convey the polymerization components through an interior of the polymerization reactor and configured to subject the polymerization components to polymerization conditions to produce a polymer slurry comprising polymer particles;
• an analysis system coupled to the polymerization reactor along the flow path, wherein the analysis system is configured to monitor a particle size of the polymer particles;
• and
• a control system coupled to the analysis system and the feed system, wherein the control system is configured to receive a signal from the analysis system indicative of the monitored particle size of the polymer particles, and is configured to adjust a flow rate of the monomer, the comonomer, the catalyst, the diluent, or any combination thereof in the feed system, in response to the signal.
