重点行业氮氧化物治理过程中，氨逃逸问题不容忽视！

Core Viewpoint - The article emphasizes the importance of precise and scientific nitrogen oxide (NOx) emission control in industries, highlighting the risks associated with excessive ammonia (NH3) injection and the need for systematic pollution management [1][2][3]. Group 1: Current Issues in NOx Control - Some companies are resorting to blindly increasing ammonia injection to reduce NOx concentrations, leading to significant ammonia escape issues that require urgent attention [1][2]. - Ammonia escape not only affects environmental quality but also increases operational costs for companies, with estimates suggesting that a typical daily glass production facility could waste 25% of ammonia, leading to additional costs exceeding 200,000 yuan annually [2][3]. Group 2: Consequences of Ammonia Escape - Escaped ammonia reacts with sulfur oxides to form ammonium sulfate, which can cause blockages and corrosion in downstream equipment, increasing maintenance costs and reducing operational efficiency [3][4]. - Local regulations are being established to limit ammonia emissions, as evidenced by a recent fine imposed on a cement company for exceeding ammonia concentration limits [3]. Group 3: Solutions for Ammonia Escape - To mitigate ammonia escape, companies should implement automatic reagent addition systems and real-time monitoring of ammonia emissions, adjusting ammonia injection based on various operational parameters [5]. - Enhancing the performance of denitrification catalysts and ensuring optimal operating conditions for denitrification equipment are crucial for minimizing ammonia escape and achieving stable NOx emission standards [4][5].
