Ka'ida: Tare da ƙasa daya, amoniya yana kawai daga gaskiya a cikin wani hanyar mai tsawo a ciciyoyi 280-420℃ don soya cikin nitrogen oxides ta nitrogen da mai.

Hanyar kimiya:

4NO + 4NH₃ + O₂ → 4N₂ + 6H₂O; 6NO₂ + 8NH₃ → 7N₂ + 12H₂O

Fa'idodi: Kafa na soya na hausance, kuma ya kamata 80% - 90%; hanyar kimiya daidai ne kuma yana iya samu wannan.

Ka'ida: Babu aiki daya na ƙasa, rubutu mai soya mai amoniya ko urea yana kawai daga cikin kira a ciciyoyi 850 - 1100 °C don soya cikin nitrogen oxides ta nitrogen.

Hanyar kimiya:

4NH₃ + 6NO → 5N₂ + 6H₂O; CO(NH₂)₂ + 2NO → 2N₂ + CO₂ + 2H₂O

Fa'idodi: Kayan aikin na daidai ya kawo kewaye da wata samar da biyu a cikin zamanin aikin.

Ka'ida: Yana haɗuwa da fa'idodin SNCR da SCR, tare da ƙaddamar da denitrification ta hanyar SNCR, da kuma oxides na nitrogen da ba a amsa ba a cikin SCR reactor.

Fa'idodi: Da fatan mai shi, ya kirashi aikin da ya buga faffoton tare da hizizin nitargin.
