After the hydrogen circulation pump stops, the emergency pressure relief valve opens – can fresh hydrogen still be supplied to the reactor, and can it remove heat?
The reactor can be replenished, resulting in less heat being carried away; after all, the amount of fresh hydrogen is much smaller than that of recycled hydrogen
The reactor can be supplemented; it dissipates less heat. It also depends on the configuration of your process – whether there is high-pressure nitrogen available; if so, nitrogen can also be used
After all, there is a limited amount of fresh hydrogen; the system is depressurized primarily to prevent overheating. Even when only fresh hydrogen is used, attention must be paid to the catalysts to avoid reduction at high temperatures.
Are you a hydrogenation unit? Generally, a separate cold hydrogen line is designed. However, high-pressure nitrogen is the best option, as long as there is gas flow through the catalyst bed. Prevent heat accumulation within the bed layer
The 5th floor is the correct answer; a cold hydrogen line is essential~~~·But high-pressure nitrogen isn’t available in every place~~
It is not recommended to add new hydrogen, as the pressure relief valve has already been activated and the system pressure is dropping rapidly; introducing new hydrogen at this point could cause the pressure in the system’s hydrogen pipeline network to drop further due to the pressure release.
