Will gas bias occur in variable-pressure air cooling for hydrogen production?

As the title suggests, it is easy to understand why there will be flow deviation when oil flows through an air-cooled tube bundle. But can flow deviation also occur when gas flows through such a tube bundle? What causes all these things?
It is highly likely that the air-cooling installation position is asymmetric
The air cooler has never been used, so there should also be issues with uneven distribution and different resistances
Dude, it’s dry air cooling; hydrogenation units are quite common.
It was fine before; it’s a problem that was discovered during recent inspections of the air cooling system.
Isn’t there water inside the medium-pressure gas converter? Also, when the processing capacity is less than 50%, it’s likely to cause flow deviation
The current processing rate is around 75%.
Then it might be a problem with the water and air cooling systems. If air cooling is involved, try removing part of it gradually, starting with the sections that allow better flow; if flow is restored, it proves that there is no issue with the equipment.
Frequently running only one side of the air cooling in winter can also cause flow imbalance. With air cooling in the hydrogen production unit, blockages are impossible to occur; we have made many improvements over the years and there has been no instance of flow deviation
Have you encountered it? How was it solved?
