Cooling water systems are exposed to many types of corrosion and scale problems. Water-formed deposits result from naturally occurring minerals precipitating from water to form scale. Scales built up on surfaces can be extremely hard and difficult to remove. These phenomena have a great economic impact, since the first involves deterioration of metallic surfaces by the medium, and the second causes loss of capacity for thermal exchange. Scaling and corrosion are usually interdependent. When non -uniform formation of scale occurs, corrosion is often present particularly under the deposit. This...

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...

Natural gas is most likely contains carbon dioxide as part from reservoir fluid composition, on other hand CO2 can be injected for enhanced oil recovery purposes. As such, corrosion control in carbon dioxide containing media is area of concern for oil field industries. Process operating parameters, especially temperature, pressure and fluid composition, are generally contributing to corrosion behavior for such conditions. Extensive investigation studies had been carried out to understand and control CO2 corrosion. CO2 dissolves in oil wells produced water forming carbonic acid which in turn...
