无动力氨回收装置应用技术总结

采用无动力氨回收装置将弛放气（放空气）中的氨提取出来，作为成品氨销售或直接用于生产尿素，增加了弛放气（放空气）中氨的附加值，同时也解决了大量稀氨水无法处理的症结，避免消耗大量的水和能源，解决了氨、肥难以平衡的问题，具有较高的节能和经济效益。介绍了无动力氨回收装置的设计、工艺流程及设备特点。

Sum-up of Technology for Use of Unpowered Ammonia Recovery Unit

An unpowered ammonia recovery unit is used to extract ammonia from the purge gas （vent gas） as ammonia product for sale or used directly in urea production, thereby increasing the added value of ammonia in the purge gas（ vent gas）, also solving the crucial problem of large quantities of dilute aqua ammonia that is unable to be dealt with, avoiding the consumption of a large amount of water and energy, keeping ammonia and fertilizer in balance, and bringing about considerable energy saving and economic benefits. An outline is given of the design, process flow and equipment characteristics of the unpowered ammonia recovery unit.
