Igice cya desulfurizasi nigikoresho cyinganda zikoreshwa mugukuraho sulfure mubikoresho fatizo, bikoreshwa cyane mukwangiza gaze ya fluu mu makara - amashanyarazi y’amashanyarazi, itanura, na gaze yumurizo. Ihame ryakazi ryayo ririmo kwitwara kwa alkaline desulfurizing (nka limestone cyangwa magnesium oxyde) hamwe na dioxyde de sulfure muri gaze ya flue, itanga umusaruro nka calcium sulfate cyangwa magnesium sulfate. Iki gikoresho kirimo gukora neza cyane, tekinoroji ikuze, nibikorwa byizewe kandi bihamye.
Igice cya desulfurizasi ikoresha alkaline desulfurizing agent kugirango ikore imiti hamwe na sulfure - irimo ibikoresho fatizo (nka dioxyde de sulfure muri gaze ya flue), bibyara umusaruro nka sulfate. Ibikoresho bisanzwe bikoreshwa muri desulfurizasi harimo limestone na oxyde ya magnesium. Tekinoroji ya magnesium oxyde desulfurizasiyo ifite ibyiza byo kuvura gaze ya flue iva mu mashanyarazi y’amashyanyarazi n’itanura ry’ibyuma, kandi irakwiriye cyane cyane ahantu hakungahaye kuri okiside ya magnesium.
