Abstract:
A method and apparatus are disclosed for metering the removal of polymer or copolymer from the take-off end of a horizontal vapor phase polymerization stirred-bed reactor. The take-off zone discharge apparatus comprises a drain valve, which can seal off the reactor when needed, followed by an automatic discharge ball valve, which controls the discharge of product from the reactor. The discharge apparatus limits vapor losses, outlet pluggage, and downtime on the reactor. The discharge apparatus also can be operated for allowing residence time flexibility, increased catalyst yields, and improved product quality.
