Green Corrosion Inhibitors

Corrosion is an inevitable fact of day-to-day life, and however, because of its technological, economic, and aesthetic significance, it always receives much attention. Most of the corrosion inhibitors are environmentally harmful and toxic synthetic chemicals. In view of the toxicity of the inhibitors, the search for an eco-friendly and non-toxic corrosion inhibitor is of great interest. Green corrosion inhibitors are of concern because of increased awareness and improvements in regulations related to the environment because of their toxicity, restrict regular corrosion inhibitors. The extracts of natural products contain compounds having oxygen, carbon, nitrogen and sulfur. Such elements facilitate compounds to absorb on the surface of metal, forming a protective film to prevent corrosion. The main purpose of this chapter is to provide a comprehensive study of technological applications of green corrosion inhibitors in different industries, such as reinforced concrete, coating, aircraft, oil and gas, acid pickling, and water industry.

Acidizing is one of the stimulation technologies in the oil and gas industry by removing scale, rust, debris or other acid-soluble particulates on the pipe tubing internal surface. The most common acid used is HCl. To avoid problems such as pipe or casing tubing leak due to acidic corrosion, during the acidizing normally applied with inhibition treatment by inorganic corrosion inhibitor with various compositions including quaternary ammonium salts, solvent and often some surfactant to strip oil from acid reactive surfaces. However, most of these compounds are not only expensive but also toxic to the marine environment. It is an obvious remark to point out the importance of low cost, green corrosion inhibitors which is safe to the environment. The wood extract has become important as an environmentally acceptable, readily available and renewable resource for wide range of inhibitors. A Caesalpinia Sappan L modified imidazoline has been synthesized and used as a corrosion inhibitor for carbon steel in API 5L X60 in HCl 1M environment.The aim of the investigation is to find low dosage-high efficiency green corrosion inhibitor.The testing techniques include wheel test weight loss measurement, Tafel polarization and Electrochemical Impedance Spectroscopy (EIS), Fourier Transform Infra-red Spectroscopy (FTIR). The results of weight loss studies correlated well with those of polarization and Impedance Spectroscopy. Inhibition performance for both Caesalpinia Sappan L modified imidazoline ( CS IMI) and Imidazoline (IMI) increases with increasing inhibitor concentration. The formulated Caesalpinia Sappan L modified imidazoline ( CS IMI), and Imidazoline (IMI) inhibitors give a greater than 90% inhibition efficiency with dosage 25 ppm at a temperature of 90-140°F. Caesalpinia Sappan L modified imidazoline (CS IMI), and Imidazoline (IMI) show comparable inhibition performance. However, at temperature 140oF, Imidazoline (IMI) seems to have a slightly better performance, indicating better thermal stability. Caesalpinia sappan bioactive agents are brazilein and chalcone, and its inhibition mechanism by physisorption obey Langmuir Isotherm, this mode will control charge transfer at surface metal and electrolyte.This result confirms that Caesalpinia sappan modified imidazoline is very promising for the development of green corrosion inhibitors for oil and gas application

Most internal corrosive conditions found in oil and gas producing equipment can be controlled through the use of corrosion inhibitors. Organic corrosion inhibitor chemistry is now well known and inhibition mechanisms are understood. There are many good inhibitor formulations available today; so many, in fact, that the producer is faced with the problem of selecting the one best suited to his requirements. Many people depend solely on various types of comparative inhibitor efficiency tests in the laboratory to evaluate and select inhibitors for use under field conditions. These tests are important as relative screening tests, but the selection of a carefully planned application program for the specific formulation is equally important.

Summary Corrosion inhibitors are widely used to control corrosion under the sweet and sour environments in the oil and gas industry. More effective and environmentally friendly corrosion inhibitors need to be developed. This paper studies a new gemini imidazoline (GIM) corrosion inhibitor, in which two hydrocarbon chains and two head groups are linked by a rigid spacer. The GIM was synthesized through the reaction of oleic acid with triethylene tetramine at 2:1 molar ratio. The performance of the GIM on inhibition of carbon dioxide (CO2) corrosion was evaluated by linear polarization resistance in sparged-beaker testing. Rotating-wheel testing was performed to evaluate the film persistency of the test inhibitors. The results showed that corrosion inhibition of the GIM was more effective at lower concentration than that of conventional imidazoline. The mixture of GIM and fatty acid also showed better film persistency than conventional imidazoline. The emulsion tendency of the GIM was less than that of conventional imidazoline. The mechanism of the highly effective GIM was studied. It showed that GIM has much-higher surface activity than conventional imidazoline. The critical micelle concentration (CMC) of GIM is several times lower than that of conventional imidazoline. Hence, the new GIM corrosion inhibitor and its mixture give more-effective corrosion inhibition at low concentration; there is also a lesser environmental effect.

Corrosion of steel constructions due to the affection of aggressive agents is one of the principal problems affecting reinforced concrete constructions. In critical cases, this phenomenon may cause static destabilisation of the construction and as a result, it is necessary to protect constructions using primary and secondary protection which significantly decreases this risk. This paper addresses the options for evaluating various types of protective anti-corrosion systems which use progressive corrosion inhibitor technology in a laboratory environment. Corrosion inhibitors efficiently slow down the course of corrosive processes on steel reinforcement and prolong the service life of building constructions. The rate of efficiency can be verified with high information capability in the laboratory by a series of testing methods.

Croton Lechleri

Croton lechleri, commonly known as Dragon’s blood, is a tree cultivated in the northwest Amazon rainforest of Ecuador and Peru. This tree produces a deep red latex which is composed of different natural products such as phenolic compounds, alkaloids, and others. The chemical structures of these natural products found in C. lechleri latex are promising corrosion inhibitors of admiralty brass (AB), due to the number of heteroatoms and π structures. In this work, three different extracts of C. lechleri latex were obtained, characterized phytochemically, and employed as novel green corrosion inhibitors of AB. The corrosion inhibition efficiency (IE%) was determined in an aqueous 0.5 M HCl solution by potentiodynamic polarization (Tafel plots) and electrochemical impedance spectroscopy, measuring current density and charge transfer resistance, respectively. In addition, surface characterization of AB was performed by scanning electron microscopy, energy-dispersive X-ray spectroscopy, and X-ray photoelectron spectroscopy techniques. Chloroform alkaloid-rich extracts resulted in IE% of 57% at 50 ppm, attributed to the formation of a layer of organic compounds on the AB surface that hindered the dezincification process. The formulation of corrosion inhibitors from C. lechleri latex allows for the valorization of non-edible natural sources and the diversification of the offer of green corrosion inhibitors for the chemical treatment of heat exchangers.

Green Corrosion Inhibitors

Corrosion in the reinforced concrete structures is a promising concern for material and structural engineers. Chemical corrosion inhibitors are usually suggested by the corrosion specialists in this regard, which adds an enormous amount of cost to the total materials charges and some are harmful to life forms. Therefore, some green corrosion inhibitors are introduced in this study which are relatively cheaper and holds good compatibility with concrete. We have highlighted the mechanisms of protection, advantages and disadvantages of different green biological corrosion inhibitors by broadly categorizing them into two types. This classification is based on the origin and mechanism of corrosion inhibition of the respective class. The first class is microbial inhibitors which prevent the onset of corrosion by making biofilms and precipitating calcite on steel surface and concrete voids respectively. And the second class is of botanical inhibitors which are the extracts of plants and protect the steel bars by forming biofilms. So both of the biological inhibitors are efficient to eliminate the corrosion of reinforced concrete structures.

High requirements in protection of steel reinforcing bar (steel rebar) from corrosion are necessary since there are multi interaction of corrosive chemicals which cause early damage of concrete buildings. Corrosion of steel in concrete can destroy the concretes and reduce concrete strength. To protect rebar from corrosion, application of corrosion inhibitor is believed to have higher performance compared to other protection systems. To date, organic inhibitors have promising methods in steel rebar protection as they are environment-friendly, compatible with concrete, cost effective and applicable in any various concrete conditions. Thus, demands in using these inhibitors tend to increase significantly. This paper reviews the applications of green corrosion inhibitor specifically highlighted in protecting mechanisms, typical plants extracted, performance in corrosion protection, and classification of green corrosion inhibitors. The corrosion resistances of carbon steels in concrete protected by green inhibitors are in focus. As summary, it can be confidently notified that green corrosion inhibitors for steel in concrete will have a prospect to be used as corrosion prevention in the future with further improvements.
