naphthenic acids in lube plants
(OP)
I'm speaking of corrosion by naphthenic acidity in furfural lube extraction plants. Can anybody tell me what procedures, other than upgrading metallurgy in the solvent recovery circuit on the extract side, and trying to reduce the TAN values of the VGOs treated,is recommended ? Russian type crudes have this acidity in ther VGOs sometimes with TAN values higher than 0.6 mg KOH/g.
Are any filming inhibitors or neutralizers been used ?
Thanks for your attention.

Neutralizing the acid is very difficult without also causing the furfural to decompose.
Shell, Exxon, Bechtel, Edeleanu, IFP all should be able to assist you. Bechtel Houston Mgr of Lube Technology Bob Earhart,(713 235 5400), may be able to assist you easily
