“…In previous study, with the same inhibitor (gum arabic), but in 1 M hydrochloric acid solution for API 5L X42 pipeline steel, the values of K ads were 10.03, 8.7, 8.4, and 7.9 L g −1 at 25, 35, 45, and 65 °C, respectively, where the values of the inhibition efficiency were almost good and constant (the maximum value is 93%) with increasing the temperature. Generally, values of ΔG° ads up to −20 kJ mol −1 are consistent with electrostatic interaction between charged molecules and a charged metal (which indicates physical adsorption) while those more negative than −40 kJ mol −1 involves charge sharing or transfer from the inhibitor components to the metal surface to form a coordinate type of bond (which indicates chemisorption) . In the present study, the value of ΔG° ads is −17.87 kJ mol −1 indicating that the adsorption of GA on API5L X70 pipeline steel surface involves physical adsorption.…”

“…Carboxymethyl cellulose (CMC) acts as inhibitor for mild steel in sulfuric acid and the inhibition efficiency was found to increase with increase in CMC concentration (the maximum value is 64% at 0.5 g L −1 CMC) but decreased with rise in temperature. [13] The inhibition efficiency of GA at 30,40,50, and 60°C in 0.1 M sulfuric acid is respectively 21.9%, 25.9%, 32.9%, and 37.9%, and for polyethylene glycol at the same temperatures is 16.6%, 32.3%, 36.3%, and 40.2%. [14] Several modifications have been done in recent days in an attempt to enhancing the effectiveness of polymers as metal corrosion inhibitors.…”

This paper aims to increase the inhibition efficiency of gum arabic (GA) for the corrosion of API5L X70 pipeline steel in sulfuric acid through the addition of halide ions (potassium iodide [KI], potassium chloride [KCl], and potassium bromide [KBr]). The synergistic effect of GA and halide ions has been studied using potentiodynamic polarization curves, electrochemical impedance spectroscopy, and surface analysis by scanning electron microscope (SEM). The results show that substantial corrosion inhibition (99%) using 2 g L−1 GA and 0.5 mM KI can be obtained in synergistic manner. The adsorption of GA in combination with iodide ions follows Langmuir adsorption isotherm. GA combined with KI acts as a mixed‐type inhibitor in sulfuric acid.

“…Weight Loss Measurements The study of corrosion and corrosion inhibition by the weight loss technique as a powerful tool is reported in many investigations [21,[35][36][37][38]. The gravimetric measurements of carbon steel in 1 M HCl without and with the addition of various concentrations of 51K2 were determined after 24 h of immersion at 25°C.…”

“…The most effective metal corrosion inhibitors for hydrochloric acid are organic nitrogen inhibitors, while for sulphuric acid the best organic inhibitors are those that contain sulphur. Organic compounds with nitrogen and sulphur act as perfect corrosion inhibitors for both acidic media [18][19][20][21][22].…”

The inhibitory effect of a new derivative of the indazole family, namely, (Z)-2-(1-methyl-5-nitro-1H-indazol-4-yl)-3-(3-nitrophenyl) acrylonitrile (51K2) against corrosion of carbon steel in 1 M HCl medium at a temperature of 25°C has been evaluated by different techniques such as gravimetric methods, potential-intensity curves, and electrochemical impedance spectroscopy. The impact of the concentration on the inhibition efficiency was also studied. The results of weight loss measurements and electrochemical analyses obtained showed that the addition of 51K2 increases the inhibition efficiency by decreasing the corrosion rate, with a maximum inhibitory efficacy of 80%. In other words, 51K2 is a good anodic-type corrosion inhibitor of carbon steel in 1 M HCl.

“…3B shows that the inhibition efficiency percentage increase with raising the concentration of PEI. This is attributed to the development of coordination bond because of overlap of the lone pair electron of the nitrogen atom with the 3d orbital of the iron atom with increasing the inhibition abilities of the PEI molecules on the metal surface 38,43 . Figure 4 describes the potentiodynamic polarization curves of HSAL steel in 3.5 wt% NaCl solution saturated with CO 2 having various concentrations of Polyethyleneimine (PEI) from 20 to 70 °C.…”

The present work studied the effect of temperature on the corrosion behavior of API X120 steel in a saline solution saturated with co 2 in absence and presence of polyethyleneimine (pei) as an environmentally safe green inhibitor. The effect of PEI on the corrosion behavior of API X120 steel was investigated using destructive and non-destructive electrochemical techniques. The overall results revealed that PEI significantly decreases the corrosion rate of API X120 steel with inhibition efficiency of 94% at a concentration of 100 μmol L −1. The adsorption isotherm, activation energy and the thermodynamic parameters were deduced from the electrochemical results. It is revealed that the adsorption of PEI on API X120 steel surface follows Langmuir adsorption isotherm adopting a Physichemisorption mechanism. Finally, the samples were characterized using scanning electron microscopy (SEM) and atomic force microscopy (AFM) techniques to elucidate the effect of aggressiveness of corrosive media on the surface morphology and the corrosion performance of API X120 steel. The surface topography result indicates that the API X120 steel interface in PEI presence is smoother than co 2 with cl − ions or cl − ions only. This is attributed to the compact protective film limits the aggressive ions transfer towards the metallic surface and reduces the corrosion rate. Moreover, PEI inhibition mechanism is based on its co 2 capturing ability and the PEI adsorption on the steel surface beside the siderite layer which give the PEI molecules the ability to reduce the scale formation and increase the corrosion protection due to capturing the CO 2 from the brine solution. High strength low alloy (HSLA) steels are widely finding its applications in oil & gas industry, thermal power plants and in aerospace industry etc. due to its improved mechanical properties, superior corrosion resistance and weldability when compared with plain carbon steel 1-4. Series of comparative studies have been focused on HSLA pipelines steels in order to understand the effect of alloying elements, heat treatments and other changeable factors on their mechanical properties and microstructure 5-8. it has been reported that the yield strength of the API X120 steel is in range 780-951 MPa based on the shape of the specimen. Moreover, the tensile strength is varied from 940 to 1023 MPa and the strength is more than X120 ksi and reaches to X120 grade according to the API standards 9-11. Corrosion is the major problem that compact the API X120 steel pipelines in the transportation of oil, gas. There are a myriad number of studies that investigate the influence of carbon dioxide with saline solution on the corrosion mechanism of different grades of steel pipelines employed in the pipeline applications 12,13. Additionally, it has been reported that the presence of carbonate ions in oilfield brine solution increases the corrosion rate of the pipelines 14-16. Several parameters have been noted for the corrosion of steel in CO 2 environment such as PH, temperature, CO 2 pres...
