Abstract

POSTUPAK I UREDJAJ ZA KATALITIČKU POLIMERIZACIJU ALFA-OLEFINA U GASNOJ FAZI, sadašnji pronalazak odnosi se na postupak i uredjaj za polimerizaciju takvih olefina, kao što su etilen ili propilen, u gasnoj fazi. Uredjaj obuhvata reaktor za polimerizaciju u gasnoj fazi (5) u koji se kontinualno uvodi suspenzija delića prepolimera u tečnom (im) zasićenom (im) ugljovodoniku-(cima). Suspenzija prepolimera se pravi u jednom ili više sudova za prepolimerizaciju (14) i kontinualno se pušta u jedinicu za post-tretiranje koja obuhvata sredstvo za degasiranje (10) u kojem se odvaja najveći deo rastvorenog (ih) neizreagovanog(ih) olefinskog(ih) monomera. Poželjno jedinica za post-tretiranje može obuhvatati sredstvo za odvajanje delića (11) za odvajanje najfinijih i/ili najgrubljih delića prepolimera iz suspenzije i/ili sredstvo za koncentrovanje (11a) za koncentrovanje suspenzije. Može se koristiti katalizator visoke aktivnosti u postupku sa smanjenim količinama prepolimernih aglomerata. Može se dobiti prepolimer sa suštinskim kvalitetom i željene veličine.
