The KDON-18000/18000 air mark provided by our company for xinjiang fengtai iron and steel co., LTD was successfully driven in 2014, and the product indexes all reached or exceeded the design value.

1.1、Under the basic design conditions of the air separation device, the performance indicators of the air separation device are as follows:

The product name	Yield Nm3 / h	The purity	Outside pressureMpa(G)	Exit temperature ℃	note
Oxygen gas	18000	≥99.6％O2	0.25	40	External compression
Liquid oxygen	300	≥99.6％O2	0.15	saturated	Into the storage tank
Nitrogen gas	10000	£100ppmO2	0.25	40	External compression
Nitrogen gas	10000	£100ppmO2	1.0	40	External compression
Liquid nitrogen	200	£100ppmO2	saturated	Too cold	Into the storage tank
Liquid argon	550	≤2PPmO2, ≤3PPmN2	saturated		Into the storage tank

note：(1)Liquid oxygen and liquid nitrogen are not simultaneously extracted.
(2)Nm3 / h refers to 0.1013 Mpa (A), 0 ℃ volume flow.
(3) The output of liquid products is multiplied by three units of oxygen production energy consumption.
1.2、Operating cycle (interval between two major heating cycles) 2 years
1.3、Warm thaw time 40h
1.4、Start-up time of the device (from the start of the expansion machine to the purity of the oxygen product) 36h
1.5、The operating load of the device is 45% -115%
