“…According to these diagrams, the different levels of corrosion can be noted between them due to different loop diameters in every system. The real and imaginary impedance values obtained for static system reveal that the corrosion process is accelerated at the highest content of amine (100 ppm), this initial observation was in agreement to the literature [14,15] except for the middle amine content (50 ppm) which retarded the corrosion process. For dynamic system, the behavior was similar to static system with the exception that the first was more aggressive because of a hydrodynamic fac- tor.…”

Investigations assessed the surface chemistry, morphology and depth profile of Hg for gas processing pipe steel coupons of API 5L-X52 after adsorption with elemental Hg at 25 0 C in the presence of air. We investigated the effect of Hg adsorption periods and surface Hg levels as well as characterizations of Hg depth profiles. We observed no reasonable correlation between surface Hg levels and Hg adsorption periods. Forms of Hg found on the top surface and in the depth profile were in oxide and elemental forms, respectively. However, most of the Hg present was superficial and did not penetrate below the surface significantly. The lowest concentration lixiviant, with 0.2 Molar iodine and 2.0 Molar potassium iodide, worked well with all ranges of Hg contamination observed, with the final surface Hg levels of less than 0.1 atom% by XPS analysis, for a relative percentage of Hg removal about 99%.

“…Dense and good adhered CO 2 corrosion layers provide a good protection by acting as physical barriers and suppressing mass diffusion [4][5][6][7]. However, this layer can be damaged or fully removed by several physical processes, such as mechanical wear, elastoplastic deformation, impingement of solid particles, and fluid shear stress [8][9][10][11][12]. Therefore, when corrosion occurs simultaneously with mechanical wear, the synergy between both degradation mechanisms does not allow simplifying the whole process as the individual contributions of corrosion and wear.…”
