“…The expired Abacavir Sulfate drug was investigated for MS protection against corrosion in 3 M HCl, according to obtained EIS results almost 72.7% inhibition efficiency was detected [28]. The expired salbutamol drug molecule as an emerging anticorrosion additive for MS corrosion in oilfield acidizing fluid was investigated [29]. The maximum inhibition efficiencies of 80 %, 89 % and 84 % were determined from weight loss, potentiodynamics study and EIS at concentration of 0.4 g L -1 respectively.…”

In this study, the application potential of the expired "Epdantoin" drug which includes phenytoin (EP) as the corrosion inhibitor was investigated. For this purpose, the electrochemical impedance spectroscopy measurements and polarization curves were obtained for 168 hours immersion period in 0.5 M HCl in the absence and presence of various concentration of EP. The experimental results were compared with quantum theoretical parameters in order to present adsorption behavior of EP. The adsorption equilibrium constant and Gibbs free energy were calculated as 5000 M-1 and -31,05 kj mol-1, respectively. The calculated HOMO and LUMO values were -6.67 eV and -0.72 eV, respectively. Results indicated that EP is a convenient candidate of corrosion inhibitor for mild steel in HCl medium.

“…16,17 In view of this, we propose a hybrid machine learning method to appraise the effects of operating parameters under a sweet corrosive environment, besides the multilayer perceptron neural network based QSAR/QSPR models for the assessment and prediction of corrosion inhibition performance of inhibitors. In our previous work, 18 we investigated hybrid genetic algorithm models (ANN-GA and ANFIS-GA) to assess and predict the inhibition efficiency of salbutamol drug molecule for mild steel in acidizing fluid. We explained that the predictive capabilities of the two methodologies (ANN-ANFIS) were evaluated in terms of different statistical parameters.…”

Co-MOF based metal organic framework was synthesized by reacting a metal ion (cobalt nitrate hexahydrate) with an organic ligand (2-methylimidazole) via a wet chemical method. The resulting material was characterized using detailed analytical methods and further was used as a self-assembly corrosion inhibitor in sweet corrosive environment. The empirical data set via electrochemical studies was modeled using adaptive neuro fuzzy inference system (ANFIS). The observed results showed that Co-MOF could significantly impede the corrosion rate of X65 steel and protect it from CO 2 corrosion. Increasing the concentration of Co-MOF in the test solution increased the inhibition efficiency up to 97% at 0.1 wt % Co-MOF with a mixed-type inhibition mechanism. In addition, the DFT/MD-simulation approach evidenced the adsorption disposition of Co-MOF in aqueous and gas phase which complement with the empirical findings. Also, the prognostic capability of the proposed algorithm based on the statistical parameters such as root-mean-square error (RMSE), chi square (χ 2 ), model predictive error (MPE) and coefficient of determination (R 2 ) were appraised. From the viewpoint of statistics, the explanatory model aligned credibly with the ANFIS algorithm. The overall findings confirmed a dense hybrid coating of the synthesized Co-MOF on X65 steel as responsible for the inhibition of the sweet corrosion.

“… 1 Acids injected into the wellbore can react with carbonate rocks and thus are able to improve the permeability of the subterranean formation. 2 , 3 However, this conventional acid system has two major drawbacks. First, because the acid–rock reaction is too fast, most of the strong acid is consumed in the near-wellbore zone, thus lowering the acidification efficiency.…”

Heterocyclic Mannich bases, N -(3-oxo-3-phenylpro-pyl)thiazol-2-aminium chloride (DTZA) and N -(3-oxo-3-phenylpropyl)-1 H -pyrazol-3-aminium chloride (DPZA), were developed for the corrosion inhibition of N80 steel in a 15 wt % lactic acid solution. Weight loss measurements, electrochemical techniques, surface characterization, and theoretical calculations were combined to investigate their anticorrosion performance and mechanism. The results showed that DTZA exhibited a satisfactory inhibitor efficiency of 97.56% with a dosage of 0.15% at 363 K, while DPZA achieved only 58.3% under the same conditions. Adsorptions of both inhibitors on the metal surface followed the Langmuir model with physical and chemical adsorptions. Based on X-ray photoelectronic spectroscopy (XPS) analysis, DFT calculations, and molecular dynamics (MD) simulations, stronger interactions between DTZA and iron than those in the case of DPZA were revealed, leading to the formation of a compact protective film on the metal surface, which is attributed to the presence of a thiazole ring in the DTZA chemical structure.
