Abstract: Synthetic ammonia is one of the most important building blocks in chemical industry and it also plays a critical role in national economy. However, during this process, a lot of energy will be consumed and it is estimated that about 10% of the global energy are used for the production of ammonia. Although the development of global economy has stimulated the high requirements for synthetic ammonia, the fierce competition is also found in this area. Therefore, how to find cheap raw materials, how to improve efficiency and decrease the cost will be most important.
In this paper, our calculation is based on Henan Lu Yi Fertilizer Plant with a capacity of producing 200, 000 tons per year. We did mass and energy balances for whole equipments by utilizing the knowledge of physical chemistry, principle of chemical engineering and reaction engineering. At the same time, we conducted technology calculation in tap water saturation, heat exchanger, water heaters, and other major equipments of this process.
Key words: Ammonia synthesis；Shift conversion；Energy balance；Technology
