Claim:
1. A polymerization process comprising: contacting an olefin with a catalyst in a polymerization reactor; polymerizing at least a portion of the olefin to form an alpha olefin reaction product, wherein the alpha olefin reaction product is in the form of a plurality of olefin polymer particles, wherein the polymerization reactor comprises a reaction mixture comprising the olefin, the catalyst, a diluent, and the alpha olefin reaction product; detecting, by sensor, a condition within the polymerization reactor; determining, by a processor, an average temperature of at least one olefin polymer particle of the plurality of olefin polymer particles based on the condition; determining an operating particle temperature threshold using a foul curve; comparing, by the processor, the average temperature of the at least one olefin polymer particle to the operating particle temperature threshold; changing one or more operating parameters in response to the comparing; and maintaining the average temperature of the at least one olefin polymer particle at or below the operating particle temperature threshold in response by changing the one or more operating parameters.
