Why is vacuum not applied in continuous reforming
Thread Content
In continuous reforming, generally: a vacuum extractor is designed into it. But during the construction process, vacuum pumps are hardly needed (they are useful though, but seemingly used rarely). Why is this?
For those that are in use now, gas replacement is carried out during maintenance; evacuation is done to ensure an effective replacement process. Regarding what you mentioned about starting up operations, I believe that in the case of hydrogen-based systems, evacuation can easily allow air to enter, which is unsafe

Some are still in use; since it is a hydrogen-rich environment, when using nitrogen as an intermediate for displacement, we employ vacuum systems to ensure an effective displacement and improve its efficiency.
