1. Förfarande för rening av rökgaser frän brännanläggningen för lukt-gaser av en sulfatmassafabrik, i vilket förfarande de svaveldioxidhaltiga 5 rökgaserna renas genom att föra tili en rökgasskrubber (1) ett neutrali-seringsmedel, som reagerar med svaveldioxid, kännetecknat därav, att som neutraliseringsmedlet används en alkalisk kalkförening, och den under reaktionen med svaveldioxid producerade kalciumföreningen tillföres (5) frän rökgasskrubbern (1) tili ett avloppsbehandlingssystem 10 (9,10,11,12) ingäende i samma sulfatmassafabrik, antingen tili avfallsvattenförsedimentering (9) av fiberhaltigt avfallsvatten, frän vil-ken den avlägsnas med slam, eller tili en avfallsvattenluftningsbassäng (11), i vilken kalciumsulfit kan oxideras tili kalciumsulfat. 15
2. Förfarande enligt kravl, kännetecknat därav, att ett syrehaltigt gasformigt medium förs (14) tili rökgasskrubbern (1) för att oxidera kalciumsulfit tili kalciumsulfat i skrubbern, varefter kalciumföreningen förs antingen tili försedimentering (9) av fiberhaltigt avfallsvatten eller tili avfallsvattenluftningsbassängen (11). 20
3. Förfarande enligt krav 1 eller 2, kännetecknat därav, att den alka-liska kalkföreningen är en av de följande eller en kombination av dessa: kalksten, CaC03, CaO, Ca(OH)2. 25 »
