Abstract

PROCEDIMENTO IN CONTINUO PER LA POLIMERIZZAZIONE IN FASE GAS O PIU' OLEFINE CH2=CHR, IN UNO O PIU' REATTORI A LETTO FLUIDIZZATO COMPRENDENTI UNA ZONA DI POLIMERIZZAZIONE ED UNA ZONA DI RALLENTAMENTO DELLA VELOCITA' DEI GAS SITUATA AL DI SOPRA DEL LETTO FLUIDIZZATO. IL REATTORE A LETTO FLUIDZZATO E' COLLEGATO CON UNA LINEA DI RICIRCOLO DEI GAS SULA QUALE SONO POSTI ALMENO UN COMPRESSORE ED ALMENO UN SISTEMA DI RAFFREDDAMENTO, PER MEZZO DELLA QUALE I GAS IN USCITA DELLA SOMMITA' DEL REATTORE VENGONO COMPRESSI, RAFFREDDATI ED INVIATI NUOVAMENTE AL REATTORE IN UN PUNTO AL DI SOTTO DELLA ZONA DI REAZIONE. IL PROCEDIMENTO E' CARATTERIZZATO DAL FATTO CHE IL MONOMERO O I MONOMERI FRESCHI DI REINTEGRO INVIATI DIRETTAMENTE AL REATTORE A LETTO FLUIDIZZATO IN UNO O PIU' PUNTI AL DI SOPRA DEL LETTO FLUIDIZZATO.
