Large-scale hydrogen production cycle
Thread Content
Why is it necessary to run the large cycle first when restarting after a hydrogen production shutdown?
How can your press rotate without cycling? Mainly temperature increase, catalyst reduction!
The large circulation is mainly used for raising the system temperature. In particular, to raise the temperature of the rear converter.
First, perform a cold nitrogen cycle, then a hot nitrogen cycle to heat up the system
Cyclic heating to save nitrogen consumption
There’s no need for a full cycle; if recovery is urgent, it’s possible to skip the hydrodesulfurization cycle
Removes heat from the furnace, increases the temperature of the medium-temperature reactor, reduces the catalyst, and generates steam
