Discusses causes of corrosion in the transportation and refining fields of petroleum industry where oil-soluble inhibitors can be used. Lists requirements of a good inhibitor. Gives a case history of use of inhibitor in one pipe line.
Refinery application of inhibitors is discussed briefly, also use of inhibitors in tanker ships carrying clean oil cargoes. Vapor space corrosion in tank ships is controlled by application of inhibitors by brush, flotation and fogging. Tests are discussed in which inhibitors were added to crude oil carried in tankers to control corrosion.
Corollary benefits of inhibitors added to petroleum products are given such as cleaner product, reduced wear in pumps, etc. Inhibitor’s effect on product quality and inhibitor costs are briefly discussed.
Tabular data on tanker ship corrosion are given.
