“…This leads us to believe that the values of the desorption potential of clays are slightly modified by the recovery of the inhibitor molecules. This result is accepted in literature [33]. Nevertheless, beyond the optimum inhibitor content, we noticed an increase of the corrosion rate.…”

Abstract. The behavior of E400 steel, a constructional steel widely used in Senegal, was studied in aqueous NaCl solution in the presence of two types of clay: volcanic tuffs, and sedimentary montmorillonite. The protection efficiency of these compounds were electrochemically assessed (corrosion potential variation curves, polarization curves and electrochemical impedance spectroscopy) at various inhibitor contents. The results obtained showed that these inhibitors present an inhibitory efficacy of about 70% for an optimal concentration of 0.60% for the tuffs and 62% for a maximum content of 0.50% for montmorillonite.

“…These problems cause a significant reduction in the heat transfer efficiency and working life of the equipment and a corresponding increase in the energy consumption of the equipment. 2 The use of organic molecules as corrosion inhibitors in cooling water systems is one of the most popular, efficient, and practical methods applied extensively to solve corrosion and scaling problems. 3 Most of the well-known inhibitors are organic compounds containing heteroatoms such as nitrogen, oxygen, phosphorus, and sulfur and/or delocalized π electrons in their molecular structure.…”

A borated aminated cellulose citrate (BACC) inhibitor was synthesized from bagasse cellulose with citric acid, diethanolamine, and boric acid by mechanical activation-assisted solid-phase reaction (MASPR) technology. The BACC was characterized using FTIR, XPS, and solid-state CP/MAS NMR. The effect of the BACC inhibitor on the corrosion inhibition of A3 steel in simulated cooling water was investigated using weight loss and electrochemical measurements. It was found that BACC mainly acted as a mixed-type inhibitor in simulated cooling water and predominantly controlled the anodic reaction; furthermore, the inhibition efficiency increased with increased BACC concentration. BACC also showed excellent scale inhibition in simulated cooling water. XRD and SEM analyses of the scale deposits showed that the surface morphology and size of the scale deposits were changed by BACC. These results indicated the potential of BACC as an effective corrosion and scale inhibitor in cooling water.

“…So, the water used as a thermal fluid in cooling circuits usually leads to three problems, namely, corrosion, scaling, and microorganism development. These phenomena are the source of a loss of the metallic material, a decrease of the thermal efficiency of the circuit, and the proliferation of microorganisms in the water, respectively, (Touir et al 2010;Srisuwan et al 2008). Indeed, iron is the principal redox-active metal in the metabolic processes of essentially all living organisms.…”

The corrosion and scale behavior of copper in industrial cooling water system were investigated via electrochemical measurements, ionic chromatography, SEM/EDAX, and X-ray diffraction analyses. It was found that the studied water has a corrosion and scale character. The EDAX and XRD analyses indicated that the major corrosion and scale products were the CuO 2 and CaCO 3 , respectively. In addition, the middle Mueller-Hinton test was also employed to evaluate the development of microorganisms for copper in make-up water solution. It is noted that bacterial colonies appeared after immersion of samples in make-up water, indicating that this water develops bacterial colonization. Finally, the influence of some operating parameters on the corrosion and scale rate was studied. It was shown that the scale rate increases with pH, temperature, and the addition of chloride and sulfide ions. It was also found that the corrosion rate increases with temperature and chloride ions and decreases with pH and immersion time.
