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.The invention relates to a method and a device for the removal of concentrated odorous gases in a cellulose factory. According to the method, the concentrated odorous gases containing sulfur compounds are collected from the odor gases of the sulfate cellulose plant and incinerated with sub-stoichiometric amounts of air to oxidize the sulfur compounds, so that at least a substantial portion of the sulfur compounds are oxidized to elemental sulfur. The elemental sulfur is recovered in a liquid or solid form. They can be returned to the process or used in other processes.
