Abstract

Kontinuerlig polymerisasjon ved bruk av gassfluidisert sjikt av olefiner, spesielt etylen, propylen, eller blandinger av disse med andre alfa-olefmer, hvor den monomerholdige resirkuleringsgassen som benyttes for å fluidisere sjiktet føres gjennom en separator. Separatoren lades med og holdes delvis fylt med væske. Medrevne katalysator- og/eller polymerpartikler separeres fra resirkuleringsgassen i separatoren og disse separerte partiklene holdes i en suspendert tilstand i væsken i separatoren. Resirkulerings- strømmen kan avkjøles for å utkondensere i det minste noe flytende hydrokarbon; den kondenserte væsken, som kan være en monomer eller en inert gass, separeres fra resirkuleringsgassen i separatoren og tilføres direkte til sjiktet for å frembringe kjøling ved utnyttelse av fordampningsvarme. Prosessen reduserer tilgroing av separatoren.
