Why is pressure relief necessary in the event of an accident in a hydrogen production plant?
Thread Content
May I ask why, in the case of an accident during hydrogen production, pressure needs to be released, while pressure must be maintained in reforming?
It should be from a safety perspective, considering avoiding overpressure
Pressure relief is used to prevent the catalyst from overheating
Is it the excess temperature of the catalyst caused by the lack of circulating hydrogen flow to carry away heat?
Yes, it’s mainly to prevent overheating!
