硝酸尾气处理方法

Methods of Treatment for Tail Gas from Nitric Acid Plant

介绍我国硝酸工业生产5种实用的尾气处理方法:氨选择性催化还原法、非选择性催化还原法、低温延长吸收法配氨催化还原法、碱吸收配氨催化还原法和碱吸收配气调优法等,并做技术经济比较。

Introduce 5 practical methods of treatment for tail gas from nitric acid industrial production in China: ammonia selective catalytic reduction,non-selective catalytic reduction,lengthening absorption method at low temperature with ammonia catalytic reduction,alkali absorb with ammonia catalytic reduction method and alkali absorb with gas optimal method,and make the technical and economic comparison.
