“…Hydrochloric acid solutions are commonly used, for example, in pickling, industrial acid cleaning, and oil well acidifying which are all processes that destroy metals. Mild steel corrodes severely during these processes, especially with the use of hydrochloric acid, which is a terrible waste of resources and money [ 2 , 3 ]. To minimize the effect of corrosion, there has been considerable industrial and scientific interest in studying corrosion control, in order to develop new, more economical and effective compounds that are often added to the acidic solution [ 4 , 5 ].…”

In this study, 1,5-diallyl-1H-pyrazolo [3,4-d] pyrimidin-4 (5H)-one (PPD) was evaluated as an anticorrosion agent for mild steel (MS) in 1 M HCl. The analysis was performed by weight loss (WL), potentiodynamic polarization measurement, and electrochemical impedance spectroscopy (EIS). The Tafel polarization showed that PPD is a mixed-type inhibitor and reaches 94% of the protective efficiency at 10−3 M. EIS results indicated that the resistance to charge transfer increases with increasing inhibitor concentration and the corrosion of MS is controlled by a charge transfer process. The inhibitor adsorption on the MS surface obeyed the Langmuir’s adsorption isotherm. Thermodynamic parameters were calculated to elaborate the corrosion inhibition mechanism. The micrographic analysis revealed the existence of a barrier layer on the electrode surface with the presence of PPD. Theoretical examinations performed by electronic/atomic computer simulations confirmed that the obtained results were found to be consistent with experimental findings.

“…Two different equivalent circuits, as depicted in Figure S4, were used to extract the EIS results, where CPE, CPE f , R s , R p , and R f are the constant phase element, the nonideal capacitance of the inhibitor film, and the resistances of solution, polarization, and the inhibitor film, respectively. Equation was used to calculate the impedance of CPE ( Z CPE ): Z CPE = Y 0 − 1 false( j ω false) − n where j , Y 0 , ω, and n are the imaginary unit ( j 2 = −1), CPE constant, angular frequency, and phase shift, respectively. In the absence of an inhibitor, the interface was composed only of CPE and R p .…”

“…The results of EIS tests support PDP measurements, indicating that P(VCap- co -MA)s can be considered potent corrosion inhibitors in H 2 S and CO 2 solutions as they protect against MS corrosion by 97 and 96.1%, respectively. Additionally, n dl and n f values range from 0.58 to 0.98, denoting that the MS surface is heterogeneous after corrosion, and the corrosion process is controlled by the mass transfer phenomenon …”

Development of Highly Efficient Dual-Purpose Gas Hydrate and Corrosion Inhibitors for Flow Assurance Application: An Experimental and Computational Study

et al. 2022

Gas hydrate and corrosion inhibitors are widely used to ensure successful and economic hydrocarbon stream flow inside the oil and gas pipelines. However, compatibility problems are observed during their co-injection into the flowlines as they have different molecular chemistry. Modifying effective gas hydrate inhibitors, such as polyvinylcaprolactam (PVCap), with some active functional groups in corrosion inhibition, can overcome compatibility issues. In this study, maleic anhydride was used as a cheap monomer to synthesize ionic N-vinyl caprolactam/maleic-based copolymers (P(VCap-co-MA)) as potential dual-purpose gas hydrate and corrosion inhibitors. The gas hydrate experiments showed that the inhibitors effectively inhibited natural gas hydrate formation and a maximum subcooling temperature of 14.6 °C achieved in a solution containing 2500 ppm P(VCap-co-MA)-3. The molecular dynamics simulation revealed that P(VCap-co-MA)-3 reduced the gas concentration in the liquid phase and occupied its adsorption sites on the hydrate surface to form a steric hindrance effect, inhibiting the gas hydrate formation. Electrochemical measurements indicated that P(VCap-co-MA)s significantly suppressed steel corrosion in oilfield-produced water saturated with H2S and CO2. P(VCap-co-MA)-3 and P(VCap-co-MA)-5 provided the highest protection of 96.9 and 96.1% in H2S and CO2 media, respectively. Moreover, simulation studies demonstrated that the inhibitors are strongly adsorbed on the steel surface to form a barrier layer on the surface, protecting against corrosive electrolytes. These findings suggest that the modification of a gas hydrate inhibitor improves not only its corrosion and gas hydrate inhibition performance but also decreases the operation costs for flow assurance in the oil and gas pipelines.

“…Chemical inhibitors are one of the most powerful methods for preventing metal degradation in an acidic solution. Furthermore, organic molecules including heteroatoms N, O, and S, as well as π bonds have demonstrated high inhibitive performance because of the adsorption capacity, lowering the corrosion action. − Adsorption of inhibitors with the formation of a protective covering on the metal surface causes metal inhibition. − Many aspects affect the degree of adsorption, such as the nature of the metals, electrolytic medium, temperature of the medium, replacement nature, electronic inhibitor structure, donor density, inhibitor solubility in the test medium, etc. − However, several studies have shown that these products are toxic and not environment-friendly, and they also require high corrosion inhibition concentrations. − As a consequence, the development of corrosion inhibitors with low toxicity and high effectiveness is critical.…”

Performance Evaluation of New Chalcone Oxime Functionalized Graphene Oxide as a Corrosion Inhibitor for Carbon Steel in a Hydrochloric Acid Solution

et al. 2022

View full text Add to dashboard Cite

This study aims to synthesize new chalcone oxime functionalized graphene oxide (CO-GO) and investigate the enhancement in corrosion protection. The morphology and structure of the synthesized CO-GO have been characterized by elemental analysis: Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermal gravimetric analysis (TGA), and scanning electron microscopy (SEM). Moreover, the effectiveness of corrosion inhibition was investigated by utilizing electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PDP). The results of the above analyses demonstrate that CO-GO has an outstanding corrosion inhibitor performance of up to 94% and acts as a mixed-type inhibitor with a primarily anodic action. The effect of temperature on a carbon steel surface indicates that the tested composites are chemisorbed. A few techniques were able to provide surface characterization such as scanning electron microscopy and ultraviolet (UV)−visible spectroscopy to confirm inhibitor adsorption on the carbon steel surface.
