【国家标准】 特大型空气分离设备

This standard specifies the basic process, type, design, inspection before delivery, mark, packaging, transportation and storage, installation and field performance test of superscale air separation plants (Hereinafter referred to as ASP).
This standard is applicable to ASP which separates air by cryogenic distillation with oxygen output no less than 60 000 m3/h and oxygen purity no less than 99.6% (volume fraction).
In this standard, the m3/h means gas volume flowrate unit at standard condition [0 ℃,101.325 kPa(A)] for oxygen and nitrogen,and the pressure unit with (A) means the absolute pressure otherwise the gage pressure.
