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 at least a portion of the recovered purge gas from the hydrocarbon recovery system in the fluff transfer system as the fluff transfer gas and optionally utilizing fluff transfer gas from the fluff transfer system as the purge gas in the hydrocarbon recovery system.

Emission free fluff transfer system and integrated nitrogen cycle

Processes for producing n-heptane from a mixture of 1-hexene and 1-octene in the presence of a suitable isomerization-metathesis catalyst followed by a hydrogenation step are disclosed. Integrated manufacturing systems for producing n-heptane with minimal waste also are disclosed.

Synthesis of n-heptane from olefins and related production systems

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.

A system including a hydrocarbon recovery system integrated with a fluff transfer system, the hydrocarbon recovery system comprising a purge column, a separator, a purge gas-hydrocarbon recovery unit, and a waste gas outlet line, and the fluff transfer system comprising a fluff transfer blower, and an extruder feed tank fluidly connected with the fluff transfer blower via a fluff transfer blower outlet line and fluidly connected with the purge column. The hydrocarbon recovery system can be integrated with the fluff transfer system via a purge column fluff transfer gas inlet line fluidly connecting a purge gas inlet of the purge column with the fluff transfer blower outlet line, such that a portion of the fluff transfer gas in the fluff transfer blower outlet line is introduced into the purge column as purge gas. Make-up gas to the fluff transfer system can come from the hydrocarbon recovery system.
