The production of petrochemicals involves the handling, treatment and processing of
hydrocarbons and organic chemicals, which are generally non-corrosive towards carbon and
low alloy-steels, however these hydrocarbons can carry a number of impurities such as water,
chlorides and acids that can generate corrosive conditions thereby compromising plant
infrastructure. Therefore, in the petrochemical industry it is necessary to develop efficient and
practical methods of corrosion control to maintain plant integrity.
