Abstract: A hydrocarbon recovery system is integrated with a fluff transfer system. The hydrocarbon recovery system is configured for contacting a wet polymer fluff with a purge gas to provide a purged polymer fluff and an overhead stream, and separating a solids stream, a recovered hydrocarbon stream, and a recovered purge gas from the overhead stream. The polymer fluff transfer system is configured to receive the purged polymer fluff from the hydrocarbon recovery system and transport the purged polymer fluff in the fluff transfer system via circulation of a fluff transfer gas. The hydrocarbon recovery system and the fluff transfer system are integrated by utilizing fluff transfer gas from the fluff transfer system as the purge gas in the hydrocarbon recovery system and/or by utilizing at least a portion of the recovered purge gas from the hydrocarbon recovery system in the fluff transfer system as the fluff transfer gas.
