催化还原法治理硝酸尾气在工业上的应用

The application of catalytic reduction method in treating nitric acid tail gas industrially

介绍了非选择性催化还原法和选择性催化还原法在硝酸生产企业的应用。通过对比2种催化工艺路线,并采用一定的处理控制手段,进行硝酸尾气治理,实现尾气中氮氧化物有效控制,达到环保要求。

This paper introduces the application of the non-selective catalytic reduction method and the selective catalytic reduction method in nitric acid plant. By contrasting two kinds of catalytic process routes and using the certain processing control means, the nitric oxides of nitric acid tail gas were trea ted and effectively controlled,and it can meet environmental protection requirements.
