摘要： 对中国石化洛阳分公司硫磺回收装置在烧氨过程中遇到的问题进行分析，结合实际操作情况，提出烧氨条件优化方案。结果表明，适当提高风气比、提高酸性气进炉温度、调节燃烧气氨的负荷和优化仪表控制方案后，一、二级反应器的入口和床层间的温差均增大，系统压力基本维持在0.038 MPa左右，急冷水中NH3-N含量控制在300 mg/L左右，取得了较好的综合效益。

Abstract: After a period of operation and analysis, the process conditions of ammonia burning at the sulfur recovery unit of SINOPEC Luoyang Branch Company were optimized. Results showed that by increasing the air/feed gas volume ratio and the inlet temperature of sour gas to furnace, adjusting the volume fraction of ammonia in sour gas and optimizing instrumentation and control, the temperature difference of reactor inlet and bed layer increased to ensure fully reactions; the system pressure was maintained at 0.038 MPa and the NH3-N content in quench water was around 300 mg/L. Good economic, environmental and social benefits were obtained.
