Regarding the pressure drop issue in hydrogen production converters
Thread Content
What are the reasons for the sudden increase in converter pressure drop during shutdown? How should it be handled
Imbalance in water-to-carbon ratio; steam is shut off while the feed gas continues to flow
The system is purged with nitrogen, and the steam supply has also been turned off
Does the water-carbon ratio control change significantly during shutdown?
It is recommended that you take samples of the circulating gas, check the lubricating oil in the compressor as well as the system flow, to prevent other gases from entering. It’s also possible that the differential pressure gauge has frozen. For reference only!
Will lubricant be carried into the system? The pressure difference is currently around 9 kilograms
Nitrogen cycle? The circulation volume is high, and the medium has changed as well
Does an increased circulation rate lead to a greater pressure drop? If it does go up, it can’t go up that much, right?
Is the circulating medium the same before and after the change in pressure difference?
