Abstract

Oppfinnelsen angår en fremgangsmåte og en anordning for fjerningen av konsentrerte luktgasser i en cellulosefabrikk. Ifølge fremgangsmåten oppsamles de konsentrerte luktgassene inneholdende svovelforbindelser fra luktgassene i sulfatcellulosefabrikken og forbrennes med understøkiometriske mengder av luft for å oksidere svovelforbindelsene, slik at minst en vesentlig del av svovelforbindelsene oksideres til grunnstoffsvovel. Grunnstoffsvovelet utvinnes i en flytende eller fast form. De kan returneres til prosessen eller anvendes i andre prosesser.
