Residue Hydrogenation Feed Tank Area
Thread Content
The bottoms of the feed tanks in the paraffin oil hydrogenation unit and the diesel hydrogenation unit are treated to prevent corrosion; then why isn’t the bottom of the feed tank in the residue oil hydrogenation unit treated in the same way?
It makes no sense at all! Does tank bottom corrosion protection matter in a tank farm? Because bottom anti-corrosion of the tank is equivalent to external anti-corrosion
