Description Present review article aims to highlight corrosion problems in refinery processing environment due to low molecular weight carboxylic acids commonly known as naphthenic acids. Various components like vacuum unit distillation column, pumps, transfer lines and exchangers are affected due to naphthenic acid corrosion in refinery environment. Naphthenic acids cause more severe corrosion in vapor phase when compared to liquid phase and velocity has an effect on the corrosion rate through wall shear stress. Corrosion intensity also depends on the physical state of the acids present in the operating system. Suitable corrosion monitoring is invariably required to check the effectiveness of any corrosion control measure. Various modern instrumental techniques for the determination of the nature of the naphthenic acids present can provide vital information such as acids' sizes and composition, which may be used in the battle against corrosion and also used to fingerprint samples from different oil fields. Different corrosion preventive measures like blending, material up gradation, use of resistant alloys and chemical treatment using corrosion inhibitors have been taken into account while discussing the problem in detail. Keywords: Corrosion, Naphthenic acids and Refinery.
