Method for Monitoring and Controlling a Polymerization Process
10 Mar 22
A method for monitoring and controlling the polymerization in a polymerization vessel by using a camera viewing unit to (a) detect features of the polymer particles, or the particles' environment, (b) compare the features to pre-defined acceptable values of these features or the environment, and (c) if a variation from the pre-defined values is detected, act on process parameters to reduce or eliminate the variation.
