Abstract

En prosess for kontinuerlig å produsere et strømningsmotstandsreduserende polymermiddel (DRA) er beskrevet. Prosessen angår blanding av en monomer og en katalysator i en minst en kontinuerlig omrørt reaktortank (CSTR) for å danne en blanding. Blandingen blir kontinuerlig injisert i et volum som kontinuerlig dannes av et termoplastisk materiale, slik som polyetylen. Det termoplastiske materialet blir periodisk forseglet for å danne en midlertidig beholder eller pose. Monomeren blir tillatt å polymerisere i den midlertidige beholderen for å danne en polymer. I en ikke begrensende utførelsesform finner polymeriseringen i posen sted innenfor et inert, sirkulerende fluid som akselererer varmeoverføring. Polymeren og den midlertidige beholderen blir så malt sammen, fortrinnsvis ved ikke-kryogeniske temperaturer, for å frembringe et partikkelformet, strømningsmotstandsreduserende polymermiddel. I en foretrukket, ikke begrensende utførselsform inntreffer oppmalingen eller pulveriseringen i nærvær av minst et organisk faststoffmalehjelpemiddel. Det partikkelformede, strømningsmotstandsreduserende polymermiddelet kan videre kombineres med et dispergeringsfluid.
