Regarding compressor charging
Thread Content
What problems might arise for a reciprocating compressor when it compresses a mixture of hydrogen and nitrogen?
The original conveying medium needs to be specified in order to conduct an analysis
It was originally used for transporting hydrogen, but now it is filled with nitrogen due to system replacement. What would happen if hydrogen and nitrogen were mixed together as the medium for transportation?
System replacement over such a short period of time should not cause any problems; during operation, it is only necessary to monitor the pressure and temperature at the primary and secondary outlets – as long as these values do not keep rising out of control, there is no issue at all； This kind of operation is common here.
Hydrogen is used to displace nitrogen, which is then released into the flare system; the mixture should not be operated for long periods, as the compression coefficients vary
During the inspection of a reciprocating compressor, a clicking sound can be heard from the cylinders; I suspect it’s a problem with the valve plates. But all the parameters of the compressor on site are normal; could there be a problem?
It’s certainly an abnormal phenomenon; it might be a fault with one of the air valves, which needs to be repaired or replaced.
Although all parameters are normal at the moment, I feel there’s a problem with the air valve; but even after reporting it, no one took it seriously. Sigh
A valve failure does not necessarily lead to a major accident right away; abnormalities in the compressor will ultimately show up as abnormalities in pressure and temperature, as well as abnormal vibrations； If these aspects remain stable, conduct more observations and inspections; after all, there is still an emergency shutdown plan, right?
