摘要:

硫浆制酸尾气中的SO2和硫酸雾含量比较高,难以满足严格的环保要求,需要对尾气进行深度治理。介绍了氢氧化钠溶液强制吸收尾气中SO2和硫酸雾的治理工艺,尾气经过深度治理后可以达到排放标准。

Abstract:

In general,the contents of sulfur dioxide and sulfuric acid mist in the tail gas of sulfuric acid plant are relatively high,which makes it difficult to conform to strict environmental criteria.To this end,the tail gas should be further treated.This paper mainly introduces the treatment technology of SO2 and acid mist in tail gas forced absorption with sodium hydroxide solution.After the further treatment,the emission can meet the relevant requirements.
