浓硝酸装置的尾气治理一直是社会和企业备受关注的问题之一，其对治理环境污染具有十分重要的意义。本文针对浓硝酸装置开车时尾气中氮氧化物排放不达标的问题，从硝酸生产的基本原理出发，结合生产实际，对浓硝酸装置尾气治理进行研究。通过对浓硝酸装置开车工艺流程的优化，解决了装置开车期间尾气排放不达标的生产瓶颈，创新实现了直硝法浓硝酸生产工艺环保开车，将多年装置开车时排放的高浓度氮氧化物尾气消除，氮氧化物排放浓度由10000mg/m3降至100mg/m3，达到排放标准，实现了装置绿色无烟环保开车，减少了装置开车时对大气的污染。

The treatment of concentrated nitric acid facility discharging has always been the focus of industries. This article focused on the problem that the concentrated nitric acid facility are not being able to meet discharging standard during start-up,and researched on the treatment of concentrated nitric acid facility discharging by discussing the fundamental principles and the practice of the concentrated nitric acid production. Process optimization of the concentrated nitric acid facility start-up solved the bottleneck in production,making direct process start-up of the concentrated nitric acid possible. The concentrations of nitrogen oxides were reduced from 10000mg/m3 to 100mg/m3,which meets the discharge standard.
