Help: Should feeding be stopped if the hydrogen fuel gas for gasoline production is interrupted?

Should feeding be stopped in case of a disruption in gasoline hydrogenation fuel gas?
For a short period of time, it’s possible to keep operating; this depends on the reaction temperature in the pre-hydrogenation reactor. By controlling the two relevant values properly, it’s safe to feed material into the desulfurization reaction system. If this cannot be ensured, feeding should be stopped, otherwise there is a risk of the reaction system experiencing excessive temperatures
Gasoline hydrogenation basically does not cause excessive temperature rise, with low reaction pressure and temperature. In the accident handling plan, a fuel gas interruption usually results in switching to a prolonged cycle operation. The feed can be cut off; there is no need to stop the raw material pump
If the fuel gas supply is interrupted, the furnace simply stops working; the temperature drops, the reaction doesn’t proceed fully, and the product becomes unsuitable. Just switch to a circular mode – there’s no need to stop the feedstock pumps!
What was said about the situation after the rain stopping is correct; the temperature gets out of control, and there is rapid cooling with hydrogen for temperature regulation; when the heating furnace stops working, the cycle length needs to be increased
After a sudden interruption in the fuel gas supply, some of the olefins from the pre-hydrogenation system end up in the desulfurization reaction system. The temperature in this reaction system does not drop as quickly; although there is cold hydrogen available, its use causes a decrease in system pressure, resulting in insufficient hydrogen pressure in the recycle gas. This can lead to excessive temperatures during gasoline hydrogenation, and such issues have occurred at other manufacturers as well. Changing the large loop is possible in a short time. It’s not possible for a long time
For Production Country V blended gasoline, it’s sufficient to extract it at a slightly lower temperature; the main goal is to raise the temperature of the reaction system
