...Abstract Proper maintenance of pipelines reduces the occurrences of failures due to internal corrosion to a remarkable degree. Primarily, the two methods employed in maintaining a pipeline are mechanical cleaning (pigging) and chemical treatment, (corrosion inhibitors & biocides) often used...

... corrosion due to reactive sulfur compounds also contained in crude oils. Efforts of mitigating NAP corrosion of existing equipment by a high TAN oil include blending with crudes of lower acids content, neutralization or removal of naphthenic acids, and the use of corrosion inhibitors. Phosphate esters...

... its usage in cooling systems due to environmental discharge regulation. To overcome these challenges, Nalco Water has developed a novel non-triazole based yellow metal corrosion inhibitor with better halogen stability, superior corrosion inhibition, and reduced aquatic toxicity compared to triazole...

... decreases. If this happens, TOL corrosion will occur, which can be severe as the pH of the condensed water will be very low (< 5). However, it is possible to mitigate TOL corrosion with the application of corrosion inhibitors. Using corrosion inhibitors to control TOL corrosion in multiphase systems...

...Abstract The Rotating Cage (RC) system is a well-known laboratory tests methodology to evaluate the materials corrosion resistance and inhibitors under flow conditions, but does not allow to perform electrochemical measurements. The adaptation of the conventional RC to an Electrochemical RC...

... less hazardous (and environmentally improved) organic acids and chelating agents. Initially, necessary corrosion inhibitors for HCl contained very hazardous chemicals including arsenic compounds and polyaromatic hydrocarbons. Over the years, these were replaced with ever improving less toxic molecules...

... of corrosion inhibitors. While some studies have been conducted on the performance of corrosion inhibitors in concrete, their performance in chloride plus sulfate environments have not been investigated. In the reported study, the performance of three corrosion inhibitors (Generic and proprietary) in simulated...

...Corrosion is a damaging process that affects the water infrastructure including its pipeline, pumps valves, and auxiliary equipment. Conventional corrosion inhibitor and especially green corrosion inhibitor will contribute to maintain effective water systems and their related natural and man-made...

...Abstract Chloride-induced crevice corrosion occurs due to the formation of hydrochloric acid solution in the creviced region. Inhibitors avoid the development of this solution or hamper its deleterious action. Anodic inhibitors are able to produce an increase of E_R,CREV and / or avoid...

... region of the pipeline steel. The frequency of the phase boundary movement affects the pitting intensity. Corrosive effects were strongly dependent on the presence of inhibitors, its concentration and phase behaviour influenced by isopropanol. Increasing the inhibitor concentration mitigates pit...

... of corrosion inhibitors, the generalized corrosion rate increases exponentially with acid concentration and temperature. This can be reduced to an acceptable level by adding appropriate concentrations of inhibitor products in order to protect and prolong the useful lifetime of the hardware present in the well...

...With 0.4 bar CO₂ and 20 ppm H₂S, both inhibitor A and inhibitor B reduced the corrosion rate to less than 0.02 mm/y, and no localized corrosion was observed. In these experiments inhibitor B behaved similarly in natural gas and dense phase conditions, and no effects...
