本设计为年产4万吨合成氨合成工段的工艺设计，合成工段是整个合成氨生产过程中的核心部分。
在全世界不可再升能源不断减少的背景下，本设计选择了相对资源较多而且最为环保的天然气为生产原料。
合成氨合成工段工艺流程为：气体→冷交换器→合成塔→换热器→废热锅炉→水冷器→氨分离器→循环机。通过查阅相关文献和资料，设计了年产4万吨合成氨合成工段的工艺流程，并且用CAD绘制了本设计的设备及工艺流程。最后对本设计的工艺流程进行了物料衡算、能量衡算，并且根据本设计及操作温度、压力按照相关标准对工艺管道的尺寸和材质进行了选择。
最后，对生产过程中所产生的硫化物进行处理，避免造成环境污染。

The design for the process design of annual output of 40000 tons of synthetic ammonia synthesis, synthesis workshop section is part of the core of the production of synthetic ammonia.
Can't l energy decreasing background in the whole world, this design choose relatively more resources and the protection of natural gas for the production of raw materials.
Synthesis of ammonia synthesis process is:
gas, cold heat exchanger, synthetic tower, heat exchanger, waste heat boiler, water cooler, ammonia separator, circulation machine. Through access to relevant literature and data, the design process of the annual output of 40000 tons of synthetic ammonia synthesis, and drawing with CAD equipment and process of the design of the. At the end of the design process for the material balance, energy balance, and according to the design and the operating temperature, pressure in accordance with the relevant standard of piping of the size and material of choice.
Finally, to deal with the sulfide produced during the production process, to
