This standard specifies the terms, product classification and specification, technical requirements, inspection and test methods, inspection rules as well as marking, packaging, transportation and storage for PSA oxygen and nitrogen plants
This standard is applicable to plants that adopt molecular sieve PSA to separate and produce oxygen or nitrogen from air at normal temperature, with oxygen output not more than 15,000m3/h and nitrogen output not more than 5,000 m3/h.
Note 1: In this standard, the output of oxygen and nitrogen is the gas quantity under the standard state, i.e. that at 0℃, 0.101 325 MPa (absolute pressure), expressed in m3.
