“…Figure shows the SEM micrographs of abraded and treated X70 substrate surfaces in corrosive CO 2 saturated oilfield formation water containing APM, polyCMCh- graft -polyMVI copolymer, and in combination with each other. The abraded metallic surface (Figure a) corroded after 12 h within the corrodent, and this could be attributed to the unhindered chloride-induced and CO 2 corrosion within the oilfield formation water. − The presence of the corrosion products in Figure b is evidence of the steel dissolution within corrosive media. Unlike steel in the blank corrodent, the presence of APM (Figure c) and polyCMCh- graft -polyMVI (Figure d) within the test medium has significantly reduced corrosion by formation of protective films on the metal surface.…”

“…Prolonged and untreated corrosion cases may lead to huge damages and the eventual leakage of the pipelines. This directly affects production and gross profits due to economic loss with adverse environmental implications. , With acetic acid (in oilfield formation water) causing significant corrosion problems due to unrestricted cathodic and anodic corrosion processes in pipelines, there is a need for corrosion mitigation . The inherent presence of organic acids during oil production makes CO 2 corrosion a complex problem.…”

In this study, the synthesis route for preparing N-(3aminopropyl)imidazole (APM) from imidazole has been reported via hydrogenation using Raney nickel catalyst. The inhibition performance of the resultant imidazoline product against pipeline steel corrosion has been investigated in CO 2 saturated acidic oilfield formation water. The contributions of carboxymethyl chitosan grafted poly(2-methyl-1vinylimidazole) copolymer (polyCMCh-graf t-polyMVI) newly synthesized from chitosan revealed a synergy of protective capacity in combination with APM. Corrosion inhibition by APM/graft copolymer conjugate is attributed to molecular adsorption and the formation of more stable protective inhibitor films on the steel surface compared to individual compounds. In-depth electrochemical corrosion investigation is reported by means of electrochemical impedance spectroscopy and potentiodynamic polarization as well as surface analytical techniques. Adsorbed ferrous carbonate phases are observed at acid pH with apparently amorphous morphologies. Modeled mechanisms of corrosion and corrosion inhibition have been illustrated from experimental evidence in line with the barrier performance on adsorbed films.

“…Pipeline is an important part of equipments, which is widely used in petrochemical, aerospace, and other industrial applications, and is extremely important in safe production. There are unavoidable erosion and corrosion during applications, which maybe lead to leakage of the pipeline because of harsh working environments [14][15][16][17][18]. The main reasons of leakage are erosion, electrochemical corrosion, turbulent and chemistry, and their interactions.…”

In the production and gathering process of coal gas, the complex composition of the coal gas, harsh environments, the complex medium, and high content of solid particles in slurry cause the equipment malfunctions and even failure because of erosion and corrosion. In the present study, COMSOL multi-physics finite element simulation software is used to simulate the erosion–corrosion behaviors of elbow in key chemical equipments. The electrochemical corrosion, solid particle erosion, chemical reaction, and turbulent flow are coupled together. The particle count method is proposed to clarify the erosion phenomenon. The simulation results show that particles with high turbulent intensity hit the wall of elbow directly, which forms a slanted elliptical erosion zone on the extrados surface at 40°–50°. The chemical reaction in turbulence has a difference in the concentration distribution of substances, and this phenomenon leads to different magnitudes of the corrosion current densities in the tube. Moreover, 1/6 released particles hit the extrados surface of the elbow. These findings are beneficial to understand the erosion–corrosion phenomena and design the elbow in key chemical equipment.
