ABSTRACT:
Corrosion of iron-containing metal surfaces in a hydrocarbon fluid having a temperature of from about 175.degree. C. to about 400.degree. C. and containing a corrosive amount of naphthenic acid is inhibited by adding to the fluid or to a feed therefor, in a total additive amount sufficient to effect corrosion inhibition in said fluid, one or more thiophosphorus compound, a salt thereof, an alkyl or aryl ester thereof, an isomer thereof, or some combination of the foregoing, thereby to effect inhibition of naphthenic acid induced corrosion in the fluid.
