ABSTRACT:
The present invention relates to a method and apparatus for controlling static charges in a fluidized bed olefin polymerization reactor. Static charges which develop in the polymer products are measured and, if they fall outside a predetermined range, static charge control agents are introduced into the reactor. By controlling the static charges in the reactor, sheeting and drooling can be controlled.
