The compressor keeps operating until the reverse reaction occurs (depending on the volume of your reactor); the pressure decreases after the reverse reaction, and then rises again.
The system pressure difference is maintained by the circulator; when the circulator stops, the pressures in all parts of the system become equal.
In my opinion, after the compressor of the circulation machine stops, it’s necessary to see how long that lasts. If it’s for a short period, additional hydrogen can be added to maintain the system’s operation; but if it lasts for a long time, then the system pressure will definitely drop, and the reactor’s temperature will also decrease
After the circulating hydrogen compressor stops, emergency pressure relief is activated; the pressure in the front part of the reaction system decreases, while the pressure in the rear part first increases and then decreases. It is also necessary to determine whether the emergency pressure relief valve is located in the cold high-pressure separator or in the circulating hydrogen liquid separation tank
