Ventilation of hydrogen gas
Thread Content
If hydrogen is released, can it be diluted with air, using seamless steel pipes to introduce it into the exhaust ducts of the workshop? It doesn’t matter which direction of entry is used, nor whether the other air inlets can provide enough airflow to dilute the hydrogen.
Also, can it be burned at the exhaust outlet?
For the evacuation of hydrogen, a flame arrester can be installed; after introducing fire-suppression steam or nitrogen, it can be evacuated directly. If it reaches the workshop’s exhaust ducts, an explosive mixture can easily form, which is extremely dangerous! Do not do this! !
Hydrogen emissions should be discharged directly through a flame arrester; they cannot be diluted with air, nor can they enter the workshop’s exhaust systems. This is because air has a wide explosive range, which makes it easy for explosive mixtures to form. Additionally, hydrogen flow can generate static electricity, and if the pipelines are not properly grounded, there is a high risk of fire and explosion.
It mainly depends on the concentration of hydrogen; try to avoid this, as it can create an explosive mixture, which is very dangerous. Why not simply direct it outside using stainless steel pipes? A flame arrester must be installed in accordance with hydrogen emission standards, and the outlet of the exhaust pipe must be at a height of more than 2 meters above the roof.
I know that the hydrogen emissions in Aksu seem to be sent to the boiler room as fuel; usually, they are released directly into the air after being fitted with flame arresters.
Install a flame arrester, keep the flow rate below 10 m/s, and it is safer to have the venting height at least 5 m above the building.
Agree with the suggestion from floor 8; never mix it with other gases.
Agree with the suggestion on floor 4; never mix it with other gases.
Hydrogen is an excellent fuel, and it’s best to recycle it. There are many technologies available for hydrogen recycling nowadays – so why not consider using them? If the concentration is high enough, it can be directly burned in a heating furnace!
What is the purity of your hydrogen? What impurities are there? The technology for hydrogen recovery is now highly mature; in the past, the excess hydrogen in our company was burned and vented after being passed through a flame arrester, but it is now being recovered and reused. The effect is really very good. If you're interested, we can communicate more. ptfll@126.com

A mixture of hydrogen and air has a wide explosion limit, making it easy to form explosive mixtures that pose serious hazards.

Hydrogen is an excellent fuel, and it would be best if it could be recycled.
