There is provided an improvement in a method for terminating a gas phase olefin polymerization reaction with a kill gas such as carbon monoxide or carbon dioxide. The improvement involves the use of a carrier gas to increase the rate of penetration of kill gas into the reaction medium. The improved method is particularly adaptable to a fluid bed reactor system.

Reactor system for rapid kill gas injection to gas phase polymerization

Method and reactor system for rapid kill gas injection to gas phase

There is provided a method for terminating a gas phase olefin polymerization reaction with a kill gas such as carbon monoxide or carbon dioxide. The method involves the use of coast-down flow of recycle gas during a failure of the power source of a compressor to carry kill gas into the reaction medium. The method is particularly adaptable to a fluid bed reactor system.
