摘　　要：80kt/a合成氨入炉原料由腐植酸煤棒替换焦炭后,半水煤气中CH4含量上升,为保证合成系统的惰性气体平衡,在1200m^3/h的氢回收装置基础上新增一套氢回收装置,两套装置并联运行,氢回收处理能力有效提升,改造后装置运行稳定,效益显著。80 kt/a after replacing coke with humic acid coal rod,the CH4 content in semi-water gas rises.In order to ensure the inert gas balance of the synthesis system,a new hydrogen recovery device is added on the basis of 1200 Nm^3/h hydrogen recovery device.The two devices operate in parallel,and the hydrogen recovery and treatment capacity is effectively improved.

关 键 词：腐植酸煤棒 氢回收 提升
