The use of chemical inhibitors to decrease the rate of corrosion processes is quite varied. In the oil extraction and processing industries, inhibitors have always been considered to be the first line of defense against corrosion. A great number of scientific studies have been devoted to the subject of corrosion inhibitors.Cationic surfactants represent only 5-6% of the total surfactant production. However they are extremely useful for some specific uses, because of their peculiar properties .They are not good detergents nor foaming agents, and they cannot be mixed in formulations which...

Surface-active agents, surfactants, are widely used and find a very large number of applications in the petroleum industry. This is attributed to their remarkable ability to influence the properties of surfaces and interfaces. Recently, one of the most important applications of surfactants is as effective corrosion inhibitors in the oil industry One of the major consumers of corrosion inhibitors is the oil industry, where they are employed to reduce the corrosion rate of different types of steel alloys in gas and oil well equipment. Both general and localized corrosion are encountered in this...
