Abstract
The present invention relates to methods for controlling fouling in the reaction zone of slurry-type olefin polymerization reactors by measuring a process operating parameter and by responding to said process operating parameter, e.g., by introducing a gaseous poison for the polymerization catalyst in response to a comparison between said measured parameter and a fouling parameter limit for said measured parameter.
