通过技术改造，在 F-T 合成油装置净化工段氨制冷单元中，通过缓冲罐储存的方法收集净化工段的废氨并用于锅炉选择性非催化还原法脱硝系统，实现了资源的回收利用，有效降低了生产成本。废氨净化系统投运后，节省了还原剂费用并降低了电能消耗，锅炉烟囱尾气中 NOx 质量浓度月平均值比原工艺降低2．3～3．1 mg／m3，同时解决了废氨燃烧所带来的二次污染问题，经济和环保效益显著。

Through technological transformation,in ammonia refrigeration unit of purification section of F-T synthetic oil plant,by method of buffer tank storage,waste ammonia in purification section is recovered and used in boiler denitrification systems with process of selective non-catalytic reduction,realizing recycle of resources,reducing production cost effectively.After putting into operation of waste ammonia purification system,expense for reducing agent is saved and electric energy consumption is reduced,the monthly average of NOx mass concentration of boiler flue gas is 2.3 ~3.1 mg/m3 lower than that of original process,at the same time,the secondary pollution problem caused by burning waste ammonia is solved,significant economic and environmental benefits are achieved.
