Abstract:
1. A method for monitoring a polymerization reaction in a fluidized bed reactor, the method comprising the steps of: (a) generating, in on-line fashion, carryover static data indicative of carryover static; (b) generating, in on-line fashion, reaction parameter data indicative of resin stickiness, where said reaction parameter data is neither carryover static data nor bed static data, and wherein acoustic emission sensors are used to generate at least some of said reaction parameter data; (c) generating, in on-line fashion, temperature data, using at least one of said reaction parameter data, where the temperature data is indicative of a characteristic of melting behavior of a polymer resin in the reactor in the presence of at least one diluents, and where the temperature data includes MRT (d) controlling the reaction in response to the data generated in steps (a), (b), and (c) in an effort to prevent the occurrence of a discontinuity event.
