... the packaging will provide protection in the recesses of their metal parts. If one were to search, volatile or vapor-phase corrosion inhibitor, in the Corrosion Journal or NACE Conference Paper search engine, the results would show more than 1,300 published papers. This number is substantially larger when you...

...%. Their molecular structures are shown in Figure 2 . Abstract Organic corrosion inhibitors (CIs) are widely employed in the oil and gas industry to protect carbon steel pipelines against internal corrosion. Inhibitor selection by corrosion engineers frequently relies on long testing procedures and protocols...

...Abstract Long-distance transmission of oil is usually carried out in large-diameter steel pipelines; water present therein may cause severe internal corrosion. An effective method of mitigating such corrosion is to inject organic corrosion inhibitors (CIs). Their surface adsorption, via...

... Understanding corrosion inhibitor deliverability is a significant component of a robust corrosion inhibitor (CI) management program. Many oil and gas companies require measurement of the residual CI concentration downstream of the injection point. Four significant components of a robust corrosion management...

...Abstract Two desirable characteristics of corrosion inhibitors is their high aqueous solubility and their low tendency to micellize. In this work, we propose that addition of a polar moiety to the terminal end of the alkyl tail of the quaternary ammonium-based corrosion inhibitors improves both...

...INTRODUCTION Abstract Organic corrosion inhibitors are widely used in oil and gas industry to mitigate the internal corrosion of oil and gas pipelines. These inhibitor molecules are known to self-assemble and form a protective layer at the metal-water interfaces. In this work, we have studied...
