Ceramic coating for acid purification reboilers
We are distilling dirty acetic acid ⇦this on eBay or Amazon [affil links] and some acidic impurities in SS 316L distillation column equiped with bottom reboiler. Bottom reboiler has tubes in Titanium and tube sheet in SS 316 L. Tubes are expanded joint to tube sheet. We observed that acid is penetrating to microscopic gap between tubes and tube sheet thus leading to corrosion.So we are thinking to do a ceramic coating. Please advise.

Most ceramics are attacked by certain acidic ions that may be present in your acid. Perhaps titanium could be a better option.
