Scavenger injection

Process for the polymerization of olefins in a polymerization reactor system including (i) a gas phase reactor having a gas outlet and one or more withdrawal lines for withdrawal of a polymer-containing stream, (ii) a recycle loop for recycling gas exiting the reactor through the gas outlet back to...

More Information
Summary:Process for the polymerization of olefins in a polymerization reactor system including (i) a gas phase reactor having a gas outlet and one or more withdrawal lines for withdrawal of a polymer-containing stream, (ii) a recycle loop for recycling gas exiting the reactor through the gas outlet back to the reactor, (iii) a polymer separation system for separating reactants from the polymer product in the withdrawn polymer-containing stream, and (iv) a recycle system for recycling reactants removed from the reactor in the withdrawn polymer-containing stream back to the reactor. A scavenger is introduced directly into one or more of the recycle loop, the polymer separation system and the recycle system.
