To understand the relationship between total acid number and sulfur content, relative to corrosivity, a complete characterization of these parameters along the distillation curve of a desalted crude oil was performed. Naphthenic acid identification and a complete physical and chemical characterization of crude oil, light vacuum gas oil, and heavy vacuum gas oil samples are also presented. The results found in this work show that there is a relationship between total acid number and corrosivity in the distilled fractions of a sample of desalted crude. Sulfur content is not directly related to the corrosive properties of the same fractions. In addition, negative fast atom bombardment (FAB) ionic spectrums of the crude oil, light vacuum gas oil, and heavy vacuum gas oil show that a more-complex mixture of naphthenic acids may not be directly associated to the total acid number or corrosivity.
