Abstract
A first polymer reactor system can include a recovery system, a reclaimed first olefin stream, a volatile first olefin stream, where the reclaimed first olefin stream and the volatile first olefin stream are in entry-fluid communication with the recovery system.
Claims28
A polymerization process comprising:
- flowing a reclaimed first olefin stream (8) to a recovery system,
- flowing a volatile first olefin stream (10) to the recovery system, and
- recovering first olefin from the reclaimed first olefin stream and the first olefin stream in the recovery system.

A polymerization process, comprising:
- flowing a reclaimed first olefin stream (8) to a recovery system,
- flowing a comonomer recirculating stream (17) to the recovery system,
- flowing a volatile comonomer stream (20) to the recovery system,
- recovering a first olefin from the reclaimed first olefin stream (8), the comonomer recirculating stream (17), and the volatile comonomer stream (20) in the recovery system.
