Hydrogen venting
Thread Content
The hydrogen consumption by various downstream users varies greatly, resulting in significant venting of hydrogen products from the hydrogen production facilities. Do anyone have any good solutions?
Reduce the valves at the downstream users to limit the flow volume.
Hydrogen production and the various hydrogenation units are not owned by the same company; it’s not very practical.
It means that the consumption downstream decreases, which leads to venting
Right, when the demand downstream increases, we increase the load; when the demand decreases, we reduce the load. Our system has pressure control, and when the pressure exceeds a certain level, it releases excess pressure
Even if it’s not the same company, this method can still be used to avoid significant fluctuations in traffic.
A large buffer tank can be added; after passing through it, the fluid is buffered before being sent to various devices.
1 A gas usage agreement is signed on a monthly basis to urge various user units to improve their production management. 2 Under this premise, a buffer tank should be added, and its size needs to be evaluated.
The solution is to control the downstream process; you can’t keep adjusting the hydrogen production load indefinitely
I asked, and it seems that the buffer tank can only address pressure fluctuations, not flow rate fluctuations? Is that really the case? Is there no other solution?
If possible, a delivery buffer tank can be installed; otherwise, it’s necessary to maintain close communication and take action promptly
