Scope

This specification stipulates the layout, scale, product specifications and equipment determination of the air separation unit, the design of process pipelines, the design principles of the automatic control system, and the storage and transportation requirements of nitrogen and oxygen. This specification is applicable to the design of nitrogen and oxygen systems of large and medium-sized air separation units newly built by petrochemical enterprises that use cryogenic air separation equipment (hereinafter referred to as "air separation equipment") to produce nitrogen and oxygen. The design of reconstruction and expansion projects for existing nitrogen and oxygen systems can be implemented with reference to this. This specification does not apply to devices that use pressure swing adsorption or membrane separation technology to produce nitrogen and oxygen.
