摘　　要：介绍了解决氮肥厂亏氨问题的８点经验：提高合成放空气中的甲烷含量，不随放氨带放气，选好放空点，保持冰机出口压力和氨贮槽压力，严格控制各级氨冷温度，用好催化剂，消除跑、冒、滴漏，搞好三气氨回收。The experience for solving the problem of deficient of ammonia in production of nitrogenous fertilizerare is present, that is increasing the contents of methane of the discharged air in synthesis, not carrying technical gases in exhausting ammonia, choosing the discharged place, keeping the exit pressures of ice-machine and that of ammonia storage, strictly controlling cooling temperature of ammonia in all steps, properly using catalyst, eliminating the leakage and recoverying ammonia of waste gases.
