Corrosion protection for the ethylbenzene unit storage tanks in the styrene plant
Thread Content
I would like to ask fellow netizens: what kind of material is used for the anti-corrosion coating on the inner wall of the ethylbenzene unit tank area, given that the storage tanks are made of Q235C?
I’m following this and I’d like to know the answer to this question as well
It is possible to line the interior with PTFE, as PTFE has excellent corrosion resistance. We can talk about this when we have time! QQ77390271
Reply to 3# *a*nhua: If it is an ethylbenzene storage tank, no internal anti-corrosion coating is required; whereas for a styrene monomer storage tank, an internal anti-corrosion coating is necessary – specifically, water-based inorganic zinc-rich paint + modified epoxy ferrochrome + phenolic epoxy coating (with the polymerization inhibitor TBC added). At the beginning, our facility used {water-based inorganic zinc-rich paint + phenolic epoxy coating (with TBC added)}, but that approach failed, and it was only later that the aforementioned method was adopted.

Styrene polymerizes easily; if a polymerization-inhibiting coating is to be used on the inner wall, what material would be most suitable for such a coating?
