Can the excess nitrogen from the refinery air separation unit be integrated into the purification air system?
Thread Content
The nitrogen purity in the air separation unit of a certain refinery is 99.99%. Due to an excess supply of nitrogen, some of it is discharged directly; the nitrogen pressure is 0.75 MPa. Is it possible to integrate this nitrogen into the purified air system, where the pressure is 0.6 MPa?
The excess nitrogen from the refinery air separation unit can be integrated into the purge air system, requiring only adjustment of the nitrogen pressure. Since the purity of nitrogen from the refinery’s air separation unit is 99.99%, it meets the requirements of the purified air system. The pressure of nitrogen needs to be adjusted from 0.75 MPa to 0.6 MPa to meet the operational requirements of the purification air system. .
No, what if the pipeline leaks and someone inhales it?
