“…This is in accordance with what numerous researchers have observed [19,20]. From Figures (8) and ( 9) and Tables ( 4) and ( 5), it can be seen that the inhibitor concentration of both the sodium nitrate and castor oil is inversely proportional to the carbon steel corrosion rate, given that the higher the inhibitor concentration, the lower the corrosion rate and vice versa.…”

In the petroleum industry, corrosion is a fundamental problem that causes many operational and commercial problems, which require careful consideration and comprehensive studies in order to discover suitable solutions. Among these problems is the occurrence of corrosion in the crude oil production equipment as well as in the transportation pipelines of petroleum products, which leads to their failure; thus, increasing the cost as a result of maintenance or replacement. To protect them from corrosion, different types of inhibitors are commonly used, in which small amounts of inhibitor are continuously injected, slowly forming a thin layer of inhibitor between them and the corrosive materials to protect them from corrosion. In this study, the performance of the corrosion process was examined under varying temperatures, namely 20, 30, 40, 50 and 60 °C, at rotational speeds of 0, 500, 1250 and 2000 rpm. The concentrations of sodium nitrate (NaNO3) inhibitor were 0, 0.5, 1.0 and 1.5 g/l of crude oil, whereas the concentrations of castor oil inhibitor were 0, 0.5, 1.0 and 1.5 ml/l of crude oil. The results demonstrated that the corrosion rate of carbon steel in the crude oil decreases with the increase in the concentration of both types of inhibitors (NaNO3 and castor oil), while it increases with the rise in temperature and rotational speed. It was determined that the maximum efficiency of the green inhibitor (castor oil) in the crude oil was 93.7% at a concentration of 1.5 ml/l, temperature of 20 °C and a rotational speed of 0 rpm, while the maximum efficiency of the chemical inhibitor (NaNO3) in the crude oil was 98.6% at a concentration of 1.5 g/l, temperature of 20 ℃ and rotational speed of 0 rpm.

“…The idea of corrosion protection with corrosion inhibitors is to produce a thin film on the surface of the material to protect it from corrosion. This is achieved by stimulating it to develop a thick anticorrosive component or by modifying the environmental properties resulting in the prevention or reduction of aggressive behaviour [8].…”

“…Among the amino acids, El-Sayed NH [62] signaled the corrosion inhibition of carbon steel in stagnant naturally aerated chloride solutions by certain amino acids including glycine, valine, leucine, cysteine, methionine, histidine, threonine, phenylalanine, lysine, proline, aspartic acid, arginine, and glutamic acid using electrochemical techniques. Results showed that all of the amino acids acted as mixed-style inhibitors while cysteine, phenylalanine, arginine, and histidine showed remarkably high corrosion inhibition efficiency at a concentration of 10 mM/dm 3 .…”

Corrosion of metals and its alloys destroys our properties, our environment, and our lives. Thus, corrosion control includes a range of developed treatments that take into account material properties, environmental characteristics, and process cost. Typical corrosion inhibitors are known for their excellent efficiency and show great promise. However, they become less used because they cause serious toxicity issues on the environment and affect human and animal health. In recent years, research has intensified on the development of green chemistry technologies, which offer new methods of synthesis and extraction of various non-toxic materials (plant extracts, oils, amino acids, rare earths, etc.), which are highly effective, environmentally acceptable, economical and easily available inhibitors. This chapter deals with a description of corrosion inhibitors with a particular emphasis given to the discussion on the different characteristic features of the green corrosion inhibitors reported in the literature as a comparative view of toxic inhibitors.

“…El-Sayed investigated the anti-corrosive effect of some amino acids, such as glycine, valine, leucine, cysteine, methionine, histidine, threonine, phenylalanine, lysine, proline, aspartic acid, arginine, and glutamic acid on carbon steel in stagnant naturally aerated chloride solutions using PP and EIS techniques. All of the amino acids acted as mixed-type inhibitor while cysteine, phenylalanine, arginine, and histidine showed remarkably high corrosion inhibition efficiency at a concentration of 10 mM/dm 3 of functional groups such as OH, SH, or phenyl in the backbone of the amino acid molecules help them undergo better adsorption [62]. Mobin et al studied the inhibitory behavior of mercapto group containing amino acid L-cysteine (CYS) on mild steel in aerated and unstirred 1 M HCl solution using weight loss (WL), PP, and EIS techniques.…”

Corrosion is an unavoidable fact in everyday life but always receive attention to control due to its technical, economical, and esthetical importance. Corrosion inhibitors are one of the most widely used and economically viable methods protecting metals and alloys against corrosion. Typical corrosion inhibitors are bio-toxic organic compounds, which have serious issue on toxicity. Considering the toxicity of the inhibitors, there is a tremendous interest in searching for an eco-friendly, and non-toxic green corrosion inhibitor. This chapter briefly discusses the importance and different methods of corrosion inhibitors with a particular emphasis given to the discussion on the different characteristic feature of the green corrosion inhibitors reported in the literature as a comparative view of organic inhibitors.
