        痠(suan)堿(jian)排氣量:80000CMH

        二氧化(hua)氮(dan)廢(fei)氣(qi): 使(shi)用硫(liu)化(hua)鈉(Na2S)與(yu)氫氧化鈉(na)(NaOH)進(jìn)行反(fan)應(yīng)。

        2 NO2 + 2 Na2S + H2O → N2 + Na2S2O3 + H2O

        Na2S +H2O H2S + NaOH

        Na2S +H2O NaHS + NaOH

        2 NO2 + 2 NaHS → N2 + Na2S2O3 + H2O

        8 Na2S2O3 + 2 NO2 + 4 CO2→ N2 + 4 Na2S4O6 + 4 Na2CO3

        4 Na2S4O6 + 2 NO2 + 8 NaOH → N2 + 16 Na2SO4 + 4 H2O

        8NO2 + 2NaHS + 8NaOH → 8NaNO2 + Na2S2O3 + 5H2O

        2 NO2 + 2 NaOH → NaNO2 + NaNO3 + H2O
