氢氧化钠废碱液在制酸尾气净化中的应用

Application of waste NaOH liquor in the purification of acid-making tail gas

介绍了利用氢氧化钠废碱液对制酸尾气进行洗涤吸收的原理、方法、工艺路线和实施效果。可将制酸尾气中SO_2、SO_3、酸雾的含量降到40mg/m^3以下,氮氧化物也大大降低,取得了很好的环境效益。

This paper introduces thepurification with use of waste NaOH lican be reduced to 40mg/m3 or lower.benefit to the environment.principle, method, process and effect of acid-making tail gasquor. SO2, SO3 and acid mist contained in acid-making tail gasNitric oxides are reduced to a large extent,which is a great
