The optimization of an industrial-scale ammonia production reactor is studied in the present work by re-designing the ammonia synthesis reactor and using a membrane. After simultaneous modeling and simulation of the ammonia synthesis reactor and the membrane unit, the maximization of ammonia production rate was investigated. The simulation results for a single pass through the reactor showed that removing methane, increasing the nitrogen flow, and combining these two cases increased ammonia production efficiency by 1 %, 15 %, and 19 %, respectively. Furthermore, for the reactor with the recycle stream, the efficiency of ammonia production can be increased by 2.74 % by re-designing the feeding strategy and optimization of the reactor. For this purpose, the PFMMD–CTFE copolymer membrane with a total area of 1550 m is required to separate methane, and the cellulose acetate membrane with a total area of 1343.9 m should be used to provide the required amount of nitrogen injection.

利用聚合物膜优化合成氨装置：重新设计氨合成反应器进料策略和甲烷去除


目前的工作通过重新设计氨合成反应器并使用膜来研究工业规模氨生产反应器的优化。通过对氨合成反应器和膜装置进行同步建模和仿真，研究了氨产率的最大化。单次通过反应器的模拟结果表明，去除甲烷、增加氮气流量以及将这两种情况结合起来，氨生产效率分别提高了 1%、15% 和 19%。此外，对于循环流反应器，通过重新设计进料策略和优化反应器，氨生产效率可提高2.74%。为此，需要总面积为1550 m2的PFMD-CTFE共聚物膜来分离甲烷，并应使用总面积为1343.9 m2的醋酸纤维素膜来提供所需的氮气注入量。
