Abstract

Det er beskrevet en fremgangsmåte for fjernelse av svoveldioksyd fra røkgass, spesielt for i et avfallsforbrenningsanlegg dannet røkgass (R), hvor det anvendes en vaskeoppløsning inneholdende alkalilut, hvorved den etter vaskingen alkalisulfat-holdige vaskeoppløsningen underkastes en elektrodialyse, hvorved det utvinnes en vandig alkalilutoppløsning og en fortynnet svovelsyre.
