Abstract

En fremgangsmåte for å bestemme cellulosefiberegenskaper, slik som restlignininnhold i kjemisk masse, med hjelp av en spektroskopisk teknikk oppnådd over et område som dekker de synlige og de nær-infrarøde områder av det elektromagnetiske spekteret, omfattende trinnene av å oppnå en prøve fra prosesslinjen, minimalt fjerne noe overskuddsvann, utsette fibrene i prøven for en stor lysstrålekilde, valgfritt å bevege prøven ved en konstant hastighet, og innhente spektraldataene over en forhåndsbestemt tidsperiode, og korrelere spekteret til en tidligere bestemt kalibrering for å bestemme Kappa-tallet. Alternativt, som et arrangement for prosesskontroll, inkluderer foreliggende oppfinnelse monteringen av eksitasjonslyskilden og den fiberoptiske sonden langs forskjellige steder i kraftkoking og blekeprosessen, slik som 1) ved trommelbrunmasse vaskerne og 2) gjennom blekeanleggfortykkere, lokalisert rett før bestrykningskniven, sonden er festet til et hurtig skannende spektrometer, via fiberoptiske kabler, med en komputersekvenserende spektral innhenting og korrelering av spekteret mot en forhåndsbestemt kalibrering, og å logge resultatene.
