What impact does each start-up and shutdown of the hydrogen peroxide production plant have on the components of the working fluid?

There are frequent planned start-up and shutdown operations; if these operations are carried out carefully, they will not have a significant impact on the components of the working fluid； However, frequent emergency stops lead to severe hydrodegradation, which has a significant impact on the condition of the working fluid; there is also high consumption of alumina and anthraquinone.

If not handled properly when parking, it can lead to the degradation of the working fluid, and even a deterioration in operating conditions!

I agree with what was said on the second floor; there’s nothing wrong with driving and parking normally! In the event of an emergency and an emergency stop is triggered, the working fluid will inevitably change! But it is the palladium catalyst that suffers the most! One more thing to mention is that the working fluid has a self-feeding function!

Owner of the post on the fourth floor, could you please explain in detail what the self-feeding function of the working fluid is?

The working fluid has a self-recovery function! Some degradation products of alumina that cannot be regenerated are partially reduced to the corresponding anthraquinones! But time is long!

I heard for the first time what was said upstairs about (the self-recovery ability of the working fluid); I’ve learned something new!

I think the impact of frequent starting and stopping on the system should be viewed in two ways. First: if the system’s condition is poor, it will lead to further deterioration of the system, to the point where it can no longer be launched. Secondly: if the system is in good condition, it will also go through a self-cleaning process. As we all know, each nitrogen cycling during driving is a process in which hydrogenation and dehydrogenation take place, with the by-products of the system being continuously regenerated through the after-treatment system, thereby further improving the condition of the system ； The nitrogen cycle is actually a process of regenerating the catalyst, further enhancing its activity ； During each start-up and shutdown process, frequent adjustments to the flow rate cause some impurities in the system to be flushed out from the bottom of the equipment and from the packing layer; these impurities are then purified through a post-treatment system, thereby keeping the system cleaner and facilitating smoother operation.

Agree with the view from floor 8. Several people said the same thing.
