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.
