With the synthesis of ammonia with chemical methods, global carbon emission is the biggest threat to global warming. However, the dependence of the agricultural industry on ammonia production brings with it various research studies in order to minimize the carbon emission that occurs with the ammonia synthesis process. In order to completely eliminate the carbon emissions from ammonia production, both the hydrogen and the energy needed for the operation of the process must be obtained from renewable sources. Thus, hydrogen can be produced commercially in a variety of ways. Many processes are discussed to accompany the Haber Bosch process in ammonia production as potential competitors. In addition to parameters such as temperature and pressure, various plasma catalysts are being studied to accelerate the ammonia production reaction. In this study, various alternative processes for the capture, storage and complete removal of carbon gas released during the current ammonia production are evaluated and the current conditions related to the applicability of these processes are discussed. In addition, it has been discussed under which conditions it is possible to produce larger capacities as needed in the processes studied in order to reduce carbon gas emissions during ammonia production in order to provide raw material source for fertilizer production and energy sector. However, if the hydrogen gas required for ammonia production is produced using a solid oxide electrolysis cell, the reduction in the energy requirement of the process and in this case the reduction of energy costs shows that it will play an important role in determining the method to be used for ammonia production. In addition, it is predicted that working at lower temperature (<400 °C) and pressure (<10 bar) values in existing ammonia production technologies, despite increasing possible energy costs, will significantly reduce process operating costs.
通过化学方法合成氨时，全球碳排放是全球变暖的最大威胁。然而，农业产业对氨生产的依赖带来了各种研究，以尽量减少氨合成过程中产生的碳排放。为了完全消除氨生产中的碳排放，该过程运行所需的氢气和能源都必须来自可再生能源。因此，氢气可以通过多种方式进行商业生产。许多过程被作为潜在的竞争者与哈伯-博施法一同讨论，用于氨生产。除了温度和压力等参数外，还在研究各种等离子体催化剂以加速氨生产反应。在本研究中，评估了当前氨生产过程中释放的碳气体的捕获、储存和完全去除的各种替代过程，并讨论了这些过程适用性的当前条件。此外，还讨论了在所研究的过程中，在哪些条件下可以根据需要生产更大的产能，以便在氨生产过程中减少碳气体排放，从而为肥料生产和能源部门提供原料来源。然而，如果使用固体氧化物电解槽生产氨所需的氢气，该过程能源需求的降低以及在这种情况下能源成本的降低表明，它将在确定氨生产所用方法方面发挥重要作用。此外，预计在现有氨生产技术中，在较低温度（<400°C）和压力（<10巴）值下运行，尽管可能会增加能源成本，但将显著降低过程运营成本。
