| 摘 要： | 72 0 0 0m3/h空分设备是 1994年从美国APCI公司引进的国内最大空分设备 ,在 1997年开始试车和试生产中发生了液空、液氮输送困难和氧化亚氮堵塞问题 ,分析与膜式冷凝蒸发器的不适当选用有关。 1999年 10月进行了完善性大修 (增加液空输送泵与一旁通阀 ) ,自此 72 0 0 0m3/h空分设备运行稳定。

| Abstract: | the 72000m 3/h air separation plant is the largest air separation plant in the country imported from APCI,USA,in 1994.The commissioning and trial production began in 1997.But it was found that difficult transfer of liquid air and liquid nitrogen and blockage by N 2O resulted from inappropriate selection of a membrane condenser/evaporator.In October 1999,an overhaul for perfection was carried out(adding a liquid air transfer pump and a by pass valve).As a result,the smooth operation of the plant was realized. |
