摘　　要：根据我国引进的Tops eS 2 0 0两段段间间接换热径向氨合成塔的原有结构参数与工况条件 ,采用拟均相一维数学模型 ,模拟计算了使用A30 1催化剂的应用效果。S 2 0 0型径向氨合成塔在现有工况条件下使用A30 1型催化剂 ,合成塔出口氨浓度可达 19 5 1%～ 2 1 33% ,氨净值比使用A110提高 1 5～ 2 5个百分点 ;最高日产合成氨可达 130 0t,在各种进塔气流量条件下 ,均可比使用A110增产 10 %～ 14% ;在同样的合成氨产量条件下 ,循环气压缩功耗可比A110降低 15 % ;废热锅炉的蒸汽产量可比使用A110提高 15 %～ 2 0 %。结果表明 ,引进的大型合成氨厂第 2次改造和催化剂更换采用A30With a pseudo homogeneous one dimentional mathematical model,the application effects of A301 catalyst have been simulated according to the original structure parameters and operating conditions of the Topse S 200 radial ammonia converter It indicates that in the present operating conditions the outlet ammonia concentration of S 200 radial ammonia conventer using A301 catalyst will reach 19 51%～21 17%(mol),1 5～2 5percent higher than that of using A110 catalyst;the highest ammonia output will reach 1300t/d,10%～14% more than that of using A110 catalyst under any inlet gas conditions;the energy consumption of recycle gas compression may be saved by 15% compared to A110 catalyst;and that the steam outlet will be increased by 15%～20% in the waste heat steam boiler than that of using A110 catalyst at the same conditions The above results indicate that our imported large scale synthetic ammonia plant will benefit much from both production increase and energy consumption decrease using A301 catalyst as a substitute for A110 catalyst,as well as from its second revamp.
