摘要:

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SO2、SO3、酸雾的含量降到40mg/m3以下,氮氧化物也大大降低,取得了很好的环境效益。

Abstract:

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