How to remove hydrogen when restarting operation after a reactor temperature spike
Thread Content
There is information on hydrogen desorption and reactor dehydrogenation; could someone experienced provide it? Thank you again.
Dehydrogenation is carried out at a constant temperature of 220° degrees and a constant pressure of 5.0 megapascals
Actually, it can be carried out according to your standard operating procedures for the hydrogen release at a constant temperature~~~
No attention is being paid to constant-temperature hydrogen evolution in hydrogenation units!
On our end, hydrogen is removed under operating pressure at a temperature of 400 degrees for 8 hours. Hope this helps you
Consult your catalyst manufacturer to obtain authoritative data on hydrogen evolution at a constant temperature
Just like my company, we are now working at another workplace and I’m not used to it
It is generally around 300–350°C; after maintaining that temperature for 2–6 hours, it is cooled down.
