6000 air separation unit: after maintenance, the compressor flow rate will not increase when it is started up again
Thread Content
The air compressor with a capacity of 6000 cubic feet per minute failed to achieve the desired flow rate after maintenance; the reason for this is unknown.
It mainly comes down to these aspects: 1. The flow meter is inaccurate； 2. Malfunction in bypass valve regulation ； 3. If it is a reciprocating compressor, the loading system has failed ； 4. Check the inlet valve
Is the air compressor vent bypass turned on?
It’s best to explain it from the air compressor to inside the tower; just by looking at the molecular sieve, it’s not possible to determine the situation. If the tower is hot, of course no air can enter it – so we need to do a material balance calculation~~
Several possibilities: 1. Flow meter failure. 2. Air compressor failure. 3. The short-circuit valve and the vent valve are not properly closed or there is internal leakage.
