Abstract
Methods and system for in-situ measurement of polymer growth within an olefin polymerization reactor are provided. The method includes polymerizing one or more olefins within a reactor at a first temperature sufficient to deposit a polymer coating therein. A second temperature is created within the reactor, and a rate of temperature change is measured from the first temperature to the second temperature. The rate of temperature change is correlated to a thickness of the polymer coating deposited within the reactor.
