If the new hydrogen generator stops operating, the existing one cannot be restarted, and the backup unit cannot either be brought online, what impact will this have on the circulation system and the reaction system, and what actions should be taken?
In the circulation machine, the pressure of the reaction system decreases, the flow rate drops, the hydrogen-to-oil ratio falls, and the reaction temperature rises. Reduce the feed rate or shut down the system, increase the amount of circulating oil, and control the reactor temperature.
There’s no drop in pressure in the new hydrogen system; reduce the reactor feed temperature
If fresh hydrogen supply is interrupted, the pressure in the reaction system drops; the turbine increases its speed to raise the circulation rate, which in turn lowers the reaction temperature. The feed rate is also reduced, and if this situation persists for too long, the circulation process must be changed
