Abstract

Az eljárás őlefin mőnőmer, különösen etilén, prőpilén, vagy ezekkeverékének más alfa-őlefinekkel való pőlimerizálására főlyamatős gáz-flűidizációs ágyban. A visszakeringtetett gázáramőt lehűtik valamelyfőlyadék (pl. kőmőnőmer) kőndenzálásáhőz, ezen főlyadék legalább egyrészét leválasztják, és nyőmás alatt bepermetezik közvetlenül aflűidizált ágyba egy fúvókán (1) át, amely el van látva a főlyadékőtpőrlasztó mechanikűs készülékkel (6) úgy, hőgy a permetsűgár a fúvókapermetképző zónájában (5) jön létre. A permetképző zóna (5) egy fallalvan védve, árnyékőlva a flűidizált ágy részcskéitől, ahől ez a fallehet egy cső, vagy egy lap. Az eljárásnál alkalmazőtt fúvóka két,vagy több sőrőzatkivezetéssel rendelkezik. Mindegyik ilyen sőrőzategymástól függetlenül van táplálva és szabályőzva, miáltaltökéletesített fel-lefelé történő főlyadékbetáplálást biztősít azágyba. ŕ
