POLYMERIZATION QUENCH METHOD AND SYSTEM

A transfer method and system (8) to discharge overflow slurry from a poly merization reactor (12) to a tank (14). The method includes thermally isolat ing a conduit extension (28) at a distal end of a transfer line (20) from a quench fluid inlet (42) to a quench chamber (15). The transfer system (10...

Beschreibung
Zusammenfassung:	A transfer method and system (8) to discharge overflow slurry from a poly merization reactor (12) to a tank (14). The method includes thermally isolat ing a conduit extension (28) at a distal end of a transfer line (20) from a quench fluid inlet (42) to a quench chamber (15). The transfer system (10) i s characterized by an annular thermal barrier around the conduit extension ( 28) that can include insulation (34) and/or thermally resistant ' support ri ng (36), and a trap- free conduit (20) in fluid communication between the re actor (12) and the conduit extension (28). The transfer method and system ca n reduce or eliminate incidents of transfer line (20) plugging in the manufa cture of isoolefin polymers and copolymers.
