DEVOLATILIZATION OF PLASTOMER PELLETS

The devolatilization of plastomer pellets is undertaken using nitrogen that is recycled in the process. Volatile hydrocarbons are removed from the nitrogen in a hydrocarbon extraction vessel (e.g. an adsorbent bed).

Zusammenfassung:The devolatilization of plastomer pellets is undertaken using nitrogen that is recycled in the process. Volatile hydrocarbons are removed from the nitrogen in a hydrocarbon extraction vessel (e.g. an adsorbent bed). In an embodiment, the recycled nitrogen contains less than 300 ppm of volatile hydrocarbons after being treated in the adsorbent bed. La dévolatilisation des granulés de plastomère est entreprise à l'aide d'azote qui est recyclé dans le procédé. Les hydrocarbures volatils sont éliminés de l'azote dans un récipient d'extraction d'hydrocarbures (par exemple un lit adsorbant). Dans un mode de réalisation, l'azote recyclé contient moins de 300 ppm d'hydrocarbures volatils après avoir été traité dans le lit adsorbant.
