Abstract

Det er beskrevet en fremgangsmåte for å separere svovelforbindelser fra en gass inneholdende karbondiok- sid og hydrogensulfid i et gassvaskesystem, hvilken gass er fremstilt ved gasslfiserlng av brukt cellulose- vaeske. I henhold til oppfinnelsen har gassvaskesy- stemet en gassvæskekontaktsone (5) som opererer ved et trykk som overskrider atmosfærisk trykk, såvel som en regenereringssone (8) som opererer ved et trykk betydelig lavere enn trykket l gassvæskekontaktsonen (5). Karbondioksid-partialtrykket i gassen, før den kommer inn i gassvæskekontaktsonen, overskrider 0,2 atmosfærer. Videre kommer gassen l kontakt med en basisk absorpsjonsvæske i gassvæskekontaktsonen og basisk væske Inneholdende alkallhydrogensulfid fjernes fra gassvæskekontaktsonen og overføres til rege- nereringssonen, i hvilken sone hydrogensulfid fjernes fra væsken inneholdende alkalihydrogensulfid og fjernes i form av en gass.
