Abstract
The present disclosure relates to methods for controlling gas phase polymerization reactors. A method for controlling a fluidized bed reactor can include forming a fluidized bed in a reactor followed by discharge of polymer product from the reactor to a product discharge tank. The polymer product can then be discharged from the product discharge tank to a blow tank and the pressure of the blow tank is measured. The pressure measured in the blow tank can then be used to control the reactor by changing one or more reactor operating inputs based on the measured blow tank pressure.
