Removal of the finished styrene polymerization inhibitor
Thread Content
For the purchased ready-made styrene, when removing the polymerization inhibitors, should it be the low-temperature inhibitor TBC or the high-temperature inhibitor DNBP? Or remove them all?
I think it’s TBC, because DNBP is already removed in the styrene plant and does not end up in the styrene product
It is indeed TBC. DNBP is carried away with the residue oil at the bottom of the tower, while TBC is generally added to the product outlet pipeline!
