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). In an embodiment, the recycled nitrogen contains less than 300 ppm of volatile hydro...

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 desvolatilización de pelotillas de plastómero se realiza con el uso de nitrógeno que es reciclado en el proceso. Los hidrocarburos volátiles se retiran del nitrógeno en un contenedor de extracción de hidrocarburos (por ejemplo, un lecho adsorbente). En una modalidad, el nitrógeno reciclado contiene menos de 300 ppm de los hidrocarburos volátiles después de ser tratados en el lecho adsorbente.
