After slagging out of the crude benzene regenerator, opening the regenerator manhole due to natural reasons
Thread Content
After the crude benzene regenerator was discharged of slag, its temperature dropped to around 70 degrees. After opening the manhole of the regenerator, natural convection occurred. Question: 1. What is the reason for this natural convection? 2. What are the natural components, or natural sources of combustion? Thank you to the masters for their detailed answers: handshake

I haven’t encountered it; could you explain the process in detail?
After the regenerator has been emptied of slag, it is planned to open the manhole in order to check for any blockages in the internal slag removal pipes and to ensure that the regeneration process is effective. The temperature inside the regenerator is around 70 degrees. Some time after the manhole was opened, black smoke began to emerge from the regenerator through that manhole; this indicates that there was spontaneous combustion inside the regenerator. I would like to know what the components responsible for this spontaneous combustion are Or explain the reasons in detail; there must be flammable materials involved. What exactly are they?
We also encountered this recently; are you using washing oil or naphthalene?
It used to be oil washing, and now it’s methylnaphthalene.
Do you produce sulfur, or ammonium sulfide? . How is the absorption effect? . .
