    • Systems and methods for producing ammonia. Nitrogen and hydrogen can be supplied to a reaction zone disposed inside an inner shell. The inner shell can be disposed inside an outer shell such that a space is formed therebetween. The reaction zone can include at least one catalyst bed in indirect heat exchange with the space. The nitrogen and hydrogen can be reacted in the reaction zone in the presence of at least one catalyst to form an effluent comprising ammonia. The effluent can be recovered from the inner shell and cooled to provide a cooled effluent stream. A cooling fluid can be provided to the outer shell such that the cooling fluid flows through at least a portion of the space and is in fluid communication with the exterior of the inner shell. At least a portion of the cooled effluent can provide at least a portion of the cooling fluid. The cooling fluid can then be recovered from the outer shell as an ammonia product.
    • 用于生产氨的系统和方法。 氮和氢可以供应到设置在内壳内的反应区。 内壳可以设置在外壳的内部,从而在它们之间形成空间。 反应区可以包括与空间间接热交换的至少一个催化剂床。 氮和氢可以在反应区中在至少一种催化剂的存在下反应,形成包含氨的流出物。 流出物可以从内壳回收并冷却以提供冷却的流出物流。 可以向外壳提供冷却流体,使得冷却流体流过空间的至少一部分并与内壳的外部流体连通。 冷却的流出物的至少一部分能够提供冷却流体的至少一部分。 然后冷却流体可以作为氨产物从外壳中回收。
