“…As a result, we may deduce that the decreasing trend of the I.E. with rising temperature is due to hexamine desorption, which should be quicker than the rate of adsorption at higher temperatures [59], as seen in Figures 5 and 6. Inhibitor compounds with hydrophobic motifs may, in addition to having polar groups that interact with the metal surface, help create protective layers.…”

The corrosion of pipelines and crude oil storage tanks was reviewed.  The influence of CO 2 on the corrosion process was estimated.  Corrosion control via heterocyclic inhibitors was addressed.This paper aims to look at how pipeline steel and crude oil storage tanks resist corrosion in aqueous carbon dioxide (CO 2 ) environments. To this aim, we have studied different inhibitors, particularly the heterocyclic inhibitor, which is used to prevent mild steel corrosion in various situations. On mild steel, the corrosionprevention mechanism of heterocyclic inhibitors is also investigated. CO 2 corrosion is the most frequent and dreaded type of corrosion in the oil and gas industry, and corrosion inhibitors are the most effective way to fight CO 2 corrosion in mild steel. Nonetheless, continual exposure to pollutants and corrosion causes such as sulfur and chromate on pipeline surfaces is unavoidable. Because of their toxicity, commercial corrosion inhibitors are being used less frequently to protect the environment. As a result of the advent of "green" chemistry and fruit waste, both of which have been demonstrated to be efficient corrosion inhibitors, plant extracts have become popular. This research aims to compile a list of carbon dioxide corrosion inhibitors that have been proved to protect against this type of attack. The material on this page is relevant to the gas and oil industries, which rely on steel pipelines and crude oil tanks to transport oil and gas products. This study will also help develop better CO 2 corrosion inhibitors for the gas and oil industries.

“…However, these corrosion inhibitors are usually toxic, expensive, and harmful to both human health and the environment . Hexamethylenetetramine (HMTA), as a conventional and environment‐friendly corrosion inhibitor, has been extensively accepted . It is a nitrogen‐containing polycyclic heterocyclic compound, which can react with acid to obtain HMTA quaternary ammonium salt .…”

A novel corrosion inhibitor, hexamethylenetetramine quaternary ammonium salt, is synthesized using hexamethylenetetramine (HMTA) and bromohexane as main reactants. The inhibitive action of HQAS on QT800-2 steel in hydrochloric acid medium is evaluated by weight-loss method, electrochemical method, and quantum chemical calculation. The obtained results show that the efficiency of 0.5 wt% HQAS inhibitor in 30 wt.% HCl solution at 363 K is 92.95% and HQAS can form an excellent synergistic effect with some additives. Polarization curves reveal that HQAS behaves as a mixed-type inhibitor with dominant anodic inhibition. Furthermore, the theoretical calculation verifies the relationship between the HQAS molecular structure and corrosion inhibition properties.

“…Unfortunately, because of the presence of Clions this acid is highly corrosive. The use of organic inhibitors is the most practical and effective method for the protection of ferrous materials [10][11][12][13][14][15][16][17]. Generally, molecules containing nitrogen, sulfur, oxygen and aromatic rings are preferred [18][19][20].…”

The corrosion inhibition of cast iron in 1 M HCl by Phenanthroline (Phen) was investigated using potentiodynamic polarization (PDP) curves, electrochemical impedance spectroscopy (EIS), surface analysis and theoretical calculations. It is found that Phen exhibits high inhibition activity towards the corrosive action of HCl and its adsorption obeys the Langmuir adsorption isotherm model. The results showed that inhibition efficiency increases with Phen concentration up to a maximum value of 96% at 1.4 mM, and decreases slightly with the increase in temperature. The free adsorption energy value indicates that Phen adsorbs on cast iron surface in 1 M HCl via a simultaneous physisorption and chemisorption mechanism. Scanning electron microscopy (SEM) micrographs, atomic force microscopy (AFM) and FTIR analysis confirmed the formation of a protective film on cast iron surface, resulting in the improvement of its corrosion resistance in the studied aggressive solution. Quantum chemical calculations at the DFT level were achieved to correlate electronic structure parameters of Phen molecules with their adsorption mode.
