摘要
In this work, the absorption-hydration hybrid method was used to recover （hydrogen ＋ nitrogen） from （hydrogen ＋ nitrogen ＋ methane ＋ argon） tail gas mixtures of synthetic ammonia plant through hydrate formation/dissociation. A high-pressure reactor with magnetic stirrer was used to study the separation efficiency. The in-fluences of the concentration of anti-agglomerant, temperature, pressure, initial gas-liquid volume ratio, and oil-water volume ratio on the separation efficiency were systematically investigated in the presence of tetrahydro-furan （THF）. Anti-agglomerant was used to disperse hydrate particles into the condensate phase for water-in-oil emulsion system. Since nitrogen is the material for ammonia production, the objective production in our separation process is （hydrogen ＋ nitrogen）. Our experimental results show that by adopting appropriate operating conditions, high concentration of （hydrogen ＋ nitrogen） can be obtained using the proposed technology based on forming hydrate.
在这个工作，吸收水和混血儿方法被用来恢复(氢 + 氮) 从(氢 + 氮 + 甲烷 + 氩) 合成的氨的尾巴气体混合物通过水合物形成 / 分离种。有磁性的 stirrer 的一个高压的反应堆被用来学习分离效率。anti-agglomerant，温度，压力，起始的煤气液体的体积比率，和分离效率上的油水体积比率的集中的影响系统地面对 tetrahydrofuran (THF ) 被调查。Anti-agglomerant 被用来为 water-in-oil 乳剂系统驱散水合物粒子进冷凝物阶段。因为氮是为氨生产的材料，在我们的分离过程的客观生产是(氢 + 氮) 。我们的试验性的结果由采用适当操作条件显示出那，高集中(氢 + 氮) 能基于形成水合物用建议技术被获得。
