Calcium desulfurization fasaha ce ta gama gari da kuma amfani da ita ta hanyar desulfurization na gas, wanda yafi hada da hanyar limestone-gypsum da kuma hanyar lime.

Hanyar calcareous-gypsum:

Ka'ida: Kankara yana so daidai zuwa a cikin gida da kuma yi shirin daga cikin wani tare da. A cikin tsakiyoyin abinda, tare da kankara yana son ruwa mai shirin da SO₂ a cikin kasance masu sauta ake yi shirin da ida sosai kankara. Idan sosai kankara yana son bincika daidai zuwa ida sosai (gypsum).

Tsarin maganin sinadaran:

Tsohuwar shirin: CaO + SO₂ + 1/2H₂O → CaSO₃·1/2H₂O

Tsohuwar bincika: CaSO₃·1/2H₂O + 1/2O₂ + 3/2H₂O → CaSO₄·2H₂O

Fadama:

Fasahar ta balaga, aikin yana da tabbaci, ingancin desulfurization yana da yawa, albarkatun masu sha suna da yawa, farashin yana da ƙarancin kuɗi, kuma ana iya amfani da gypsum na samfurin gaba ɗaya.

Tare da limes:

Ka'ida: Lime (CaO) yana iya a cikin tsarin desulfurizing dai dai a ce limes slurry, an yi rufa suka da sulfur dioxide a cika calcium sulfite, an sauke kula a cika calcium sulfate.

Tsarin maganin sinadaran:

Tsohuwar shirin: CaCO₃ + SO₂ + 1/2H₂O → CaSO₃·1/2H₂O + CO₂

Tsohuwar bincika: CaSO₃·1/2H₂O + 1/2O₂ + 3/2H₂O → CaSO₄·2H₂O

Fadama: Saddarar rufa ne kawo da hanyar desulfurization ne gaba.

Ana amfani da calcium desulfurization a cikin wutar lantarki, karfe, sinadarai da sauran masana'antu.
