This article provides useful information on the occurrence of corrosion in crude oil refinery units, namely, crude unit, catalytic and thermal cracking units, hydroprocessing units, amine sweetening units, and sour water units. Types and applications of corrosion inhibitors, namely, neutralizers, filming inhibitors, scavengers, microbiocides, and anti-foulants and scale inhibitors, are reviewed. The article describes the direct and indirect corrosion monitoring methods used to reduce equipment damage due to corrosion events and to assess the reliability and useful service life of process equipment.
