Chemical Processing Industry: Corrosion Dynamics and Prevention Techniques

The main issue with the chemical processing industry and industrial circulating systems is the occurrence of corrosion, particularly metallic corrosion. Such hard deposits are formed due to the corrosive chemicals, brine solutions, and other operating conditions. Thus, reducing the effectiveness of the internal diameter of the process flow lines is most important. The existence of salts, acid liquids, and gases in the inner lines of liquids and gasses, such as water and oil wells, expedites electrochemical reactions that lead to corrosion and sometimes scaling. Corrosion and scaling are interrelated, but their basic phenomenon is different. Scaling on the metallic structures can decline or enhance the dissolution rate depending on the physiochemical characteristics of the metal surface at that time. At the same time, corrosion problems are much more severe. This chapter reviewed the material cause and process corrosion in the chemical processing industry using examples of different types of chemical materials and corrosion in specific industries. This chapter also provides a comprehensive understanding of corrosion in the chemical processing industry, which permeates various aspects of operations from safety and environmental responsibility to economic efficiency and technological innovation.
