Catalytic self-preservation
Thread Content
In catalytic self-protection, after the self-protection action, are the external circulation slide valve and the external heat extraction slide valve in a closed state? ? ? ?
It depends on that self-protection maneuver; P
When the main air supply is in self-protection mode, it is in the off state.
After our main valve engages in self-protection, the external slide valve does not participate in this self-protection mechanism
If it’s not involved, the external heat relief valve won’t operate, right? Won’t the catalyst in the regenerator fall into the coking tank? Will it not affect the next step and the main wind? I don’t know what form you guys are in?
Our regenerator is a conventional single regenerator
Use an external heat slide valve? This one should not participate in self-protection.
