    摘要： Provided is a method for monitoring a polymerization reaction in a fluid bed reactor to determine in on-line fashion a current value, and preferably also a limiting value, of a stickiness control temperature, and optionally controlling the reaction in response thereto in an effort to prevent occurrence of a discontinuity event. The stickiness control temperature is a temperature indicative of a characteristic of melting behavior of polymer resin in the reactor, and may be indicative of occurrence of resin sheeting or another discontinuity event. Optionally, a predetermined relation between values of acoustic energy in the reactor and values of a stickiness control temperature is used to provide error checking for determination of the stickiness control temperature, or a current value of the stickiness control temperature is determined from acoustic data and a predetermined relation between values of an acoustic condition in the reactor and values of the stickiness control temperature.

    摘要： In some embodiments, a method or system for assessing fluidization quality of a fluidized bed reactor, including by: (a) generating at least one set of temperature data indicative of temperature at a location within the reactor as a function of time during operation of the reactor; (b) generating transformed data by performing a Fourier transform on each said set of temperature data; (c) generating filtered, transformed data by high-pass filtering the transformed data to remove low frequency components thereof (preferably including the frequency component whose frequency is the natural frequency of the cooling control loop); and (d) determining at least one indication of the fluidization quality from the filtered, transformed data. In some embodiments, the reactor has a cooling control loop having a natural frequency and the frequency components removed during step (c) include a frequency component whose frequency is the natural frequency. In some embodiments, step (a) includes the step of generating at least two sets of skin temperature data, each indicative of skin temperature as a function of time at a different elevation within the fluidized bed. Some embodiments enable diagnosis of poor fluidization or mixing in the bed of a fluidized bed reactor, by analyzing Fourier-transformed, filtered skin temperature data.
