摘要
研究了碳酸钠(NaeCO3)溶液吸收处理硫化氢(H2S)气体的效果。常温(20℃)常压下。当Na2CO3溶液质量浓度为10g/L、H2S空间速度和初始质量浓度分别为511(L·min)和200mg/m^3时,可以得到以下结论:碳酸钠溶液吸收硫化氢的穿透时间是570min;在穿透时间570min内吸收效率维持在80%以上;吸收液pH值维持在9—12之间;吸收液pH=9.5时,吸收效率可以维持在80%以上。
Absorption of hydrogen sulfide by sodium carbonate solution was studied. The through - time for the absorption of hydrogen sulfide by sodium carbonate solution was 570 min, with more than 80% of the efficiency and pH 9 - 12 when hydrogen sulfide (200 mg/m^3 ) go through sodium carbonate solution ( 10 g/L) at 5 L/min under normal temperature and air pressure.
