采用碱液回收外排尾气中的氧化氮生产硝酸钠的工艺研究

Process Research of Sodium Nitrate from Nitrogen Oxide of Sodium Hydroxide Water Tail Gas

采用碱液(纯碱或烧碱)对水吸收后外排尾气中的氧化氮回收工艺进行了研究,大幅度降低了外排尾气中氧化氮的排放量,有效地控制了氧化氮对环境造成的影响,并得到产品硝酸钠,取得了良好的社会效益与经济效益。

This text introduced sodium carbonate and sodium hydroxide water absorption exocytosis tail gas nitrogen oxide recycle. Technics to do reserch, vast scale to decrease the water absorption exocytosis tail gas nitrogen oxide. Ineffect to control nitrogen oxide, environmental impact to get the product sodium nitrate to acquire fire social economy benefit.
