Sulfurization unit ye izini minɛn ye min bɛ kɛ ka kisɛ bɔ fɛnɲɛnamafagalanw na, min bɛ kɛ ka caya gazi bɔlenw bɔli la kɔɔri-kuran feereyɔrɔw la, forow kɔnɔ, ani kemikɛli gazi la. A ka baarakɛcogo ye alkaline desulfurizing agent (i n’a fɔ calcium walima magnesium oxide) ni sulfure dioxyde min bɛ gazi bɔlen na, o ka ɲɔgɔn sɔrɔ, ka kɔfɛfɛnw bɔ i n’a fɔ calcium sulfate walima magnesium sulfate. Nin minɛn in bɛ ni desulfurization baarakɛcogo ɲumanba ye, a ka fɛɛrɛ kɔgɔlen don, ani a baarakɛcogo bɛ se ka da a kan ani a bɛ sabati.
Sulfure bɔli yɔrɔ bɛ baara kɛ ni alkaline desulfurizing agent ye walasa ka kemikɛli kɛ ni fɛnɲɛnamafagalanw ye minnu bɛ ni kisɛkisɛ- ye (i n’a fɔ kisɛkisɛ gazi bɔlen gazi kɔnɔ), ka kɔfɛfɛnw bɔ i n’a fɔ sulfate. Sulfure fura minnu bɛ kɛ ka caya, olu ye kalkɛri ni manje ɔkisidi ye.
