Investigation of the corrosion inhibition performances of various inhibitors for carbon steel in CO2 and CO2/H2S environments

ABSTRACT The corrosion inhibition performances of thiourea (TU), l-cysteine (CYS), sodium dodecyl sulfonate (SDS), tetradecyl trimethyl ammonium bromide (TTAB), N-benzyl pyridinium chloride (BPC) and imidazoline quaternary ammonium salt (IAS) in CO2-saturated and CO2/H2S coexistent brine solutions were investigated by electrochemical measurement, weight-loss test, molecular dynamics simulation and SEM observation. The results show that H2S can remarkably affect the adsorption of some inhibitors on the steel surface and the inhibition performance. In detail, the inhibition performances of TU, CYS and SDS, which are effective in the CO2 environment, deteriorate in the CO2/H2S environment. However, the cationic inhibitors (TTAB, BPC and IAS) exhibit good inhibition performance in the CO2/H2S environment possibly because of a relatively strong interaction between inhibitor cations and HS− ions. The finding of this study delivers a provable method to predict the performance of inhibitors in the aggressive solution containing H2S.

3-Mercaptopropionic Acid as Corrosion Inhibitor for Carbon Steel in CO2 Aerated 1% NaCl Solution with Buffer Control-pH

In this research, 3-Mercaptopropionic acid (MPA) as corrosion inhibitor of carbon steel in CO2 aerated 1% NaCl solution with buffer pH adjustment has been studied by means of electrochemical impedance (EIS) and polarization (Tafel plot). MPA was found to be an effective carbon steel inhibitor. Percentage inhibition efficiency (IE %) calculated by both Tafel plot and EIS, ranged from 85% to 90%. MPA was found to affect the cathodic processes and act as cathodic-type inhibitors. Mechanism of inhibit corrosion by adsorption mechanism leads to the formation of a protective chemisorbed film on the metal surface film which suppresses the dissolution reaction and the hydrogen evolution reaction is activation controlled.

Corrosion Study of Carbon Steel in CO2 Loaded Amine-Amino Acid Solutions-Case of Mixtures of NMethyldiethanolamine and L-Arginine

This research presents an electrochemical corrosion investigation to quantify the corrosiveness of carbon steel in blends of methyldiethanolamine (MDEA) and arginine (Arg) at two molar concentration and different solvent proportions. The selected temperatures range varied from 20 °C to 50 °C and the CO2 partial pressure was in the range of 49-100 kPa. The obtained data showed increased corrosion rate with increased CO2 partial pressure and increased the temperature of the solution. However, when added to MDEA, arginine was found to act as an inhibitor, the higher Arginine proportion in the mixture, the more inhibition effect was observed.

Application of Anise Extract for Corrosion Inhibition of Carbon Steel in CO2 Saturated 3.0% NaCl Solution

The corrosion inhibition of carbon steel in CO2-saturated 3% NaCl solution by anise extract (AE) dissolved in ethylene glycol (EG) was studied using weight loss, electrochemical and surface analysis (AFM) techniques. Inhibition efficiency increased with increase in AE concentration and temperature, reaching maximum value of 93% at 400 ppm AE concentration. Polarization results show that AE functions as a mixed-type inhibitor. Corrosion inhibition is assumed to occur by physicochemical adsorption following Langmuir adsorption isotherm model. Morphological studies of the carbon steel electrode surface undertaken by AFM confirm the adsorption of the extract on the metal surface.

Formation of Nano-Scale FeCO<sub>3</sub> Protective Corrosion Product in Carbon Dioxide-Saturated 3% Sodium Chloride Solution

Corrosion of carbon steel in CO2 saturated NaCl solution contains the formation of FeCO3, as a corrosion product. The protective property of the formed FeCO3 scale layer to corrosion in brine solutions containing CO2 was established as the possible cause of the corrosion rate decrease above 60 °C. In this study, formation of nanoscale FeCO3 film as a corrosion product of X52 carbon steel in CO2-Saturated 3% NaCl solution was investigated. Result showed that corrosion rate decreased after precipitation and formation of protective FeCO3 film in high temperature and high bulk solution pH.

Corrosion Inhibition by Synthesized Oleic Chains Imidazoline of Coconut in 3% NaCl Solution and CO2(g) Saturated 3% NaCl Solution

The damage caused by corrosion on the pipelines used in transport of oil brings deterioration and important economics losses, besides the irreversible social loss that comes as a consequence. The aqueous solution that flows with the oil in the pipelines as like as the 3% NaCl solution, are which give the aggressiveness to it. The presence of gases, such as CO2, increases the aggressively of the environment. The use of inhibitors of corrosion is one of the most practical methods against corrosion phenomena. This work reports the results of some traditional electrochemical techniques on the corrosion inhibition of 1018 carbon steel in CO2(g) saturated 3% NaCl solution using an inhibitor composed of oleic coconut base. The electrochemical measures shown that the corrosion rate increases during the presence of gas prevailing in the microscopic studies the suddenly surge of pitting and the typical layers of inhibitor on the surface of the material.
