Excuse me: After the reforming hydrogen circulation machine is stopped, will it be restarted again?

Excuse me: During normal production, after the reforming hydrogen circulation machine is stopped and then restarted, it may be due to the large temperature difference between the reactor and the plate exchanger that internal leakage occurs in the plate exchanger. How to solve this problem. Thanks.
To slowly absorb hydrogen, just like this trick.
The only way to gradually increase the bed temperature is by slowly distributing hydrogen. Don’t do it too hastily.
There is no good way, the heating and cooling conditions for board replacement are so harsh. When the hydrogen circulation machine stops, the flame must be extinguished. Even if it can be started immediately, the temperature will definitely rise and fall suddenly, but the catalyst must be protected, so...
