Abstract [sv]

Vid kemisk massatillverkning finns behov av mättekniker som möjliggör ytterligare optimering av processen. Möjligheten att analysera svartlut med hjälp av aktiv akustisk spektrometri utreddes genom att ett online instrument konstruerdes och installerdes på ett pappersbruk. Analyser med multivariata metoder utfördes på resultaten. På grund av yttre omständigheter försenades arbetet, och ett tillräckligt dataunderlag för en definitiv slutsats erhölls ej. En rad vidare arbeten föreslås.

Abstract [en]

There is a need for additional process monitoring techniques in the production of chemical pulp. The possibility of analyzing black liquor by active acoustic spectrometry was investigated by constructing an on-line instrument and installing it in a chemical pulp mill. The results were then analyzed with multivariate methods. Due to unforeseen delays a sufficient amount of data could not be collected, and therefore a definitive conclusion could not be reached. Further work is suggested.
