摘 要 本设计为年产10万吨合成氨厂氨回收工段车间布置的三维设计对合成氨有效地解决合成氨尾气的污染，创造经济效益，符合“节能减排、减污、增效”的要求。 关键词：氨回收 工艺流程 车间布置 三维设计 Abstract This is designed to produce 100,000 tons of synthetic ammonia plant ammonia plant layout recovery section of three-dimensional design. The design for the recovery section for ammonia plant layout were designed using the section dilute ammonia absorption ammonia generated during Chi deflated and gas tank of ammonia, and a purity of 99.5% or more of ammonia by distillation. The process did recycle ammonia, the ammonia content in the exhaust gas is less than 0.1%, effectively solve the problem of pollution exhaust ammonia, and ammonia recovery by creating certain economic benefits, in line with the energy saving, emission reduction, pollution reduction, efficiency requirements.In the workshop the design process, the process for the 13 sets of equipment for the layout and design of three-dimensional arrangement, two ammonia circulating pump disposed within the plant, the remaining equipment are used open layout, ammonia evaporation tower and ancillary equipment with a steel frame structure, arrangement and use of difference relations. The entire device are arranged in line with the relevant regulatory requirements of the petrochemical industry plant layout.
