Caprylic acid showed the best behavior, while maleic acid proved the highest corrosion rate; benzoic and tartaric acids showed good inhibition effect. carbon steel efficiency inhibitor packaging VCI INTRODUCTION Volatile...

...Abstract Hydrogen sulfide gas produced by sulfate reducing microorganisms (SRM) creates significant challenges in the petroleum industry including corrosion concerns, product devaluation, and significant health risks. Biocides and inhibitors are often employed to control these detrimental...

... of corrosion inhibitors used in the oil and gas industry are based on amphiphilic molecules. These molecules are composed of at least two parts – a highly-polar or ionized functional group that is hydrophilic in nature (head group) and another part that is hydrophobic (tail), which is usually medium to long...

... inhibitors which are responsible for inhibition of steel in acidic solution. The framework consists of modules like data preprocessing, descriptor selection and model building. A robust predictive model for multiple class of corrosion inhibitors was developed using advanced machine learning algorithm...

For comparison purposes, tests were carried out on pure compounds (dosage 0.1 M) and in the alkaline solution without added inhibitors. All tests were performed adding chlorides 0.1 M. For each...

...Abstract There are several types of CO₂ absorption processes. Particularly in the process with hot potassium carbonate solution, corrosion inhibitor is added to prevent corrosion of carbon steel process equipment. However, in some cases, the inhibitor may not work beneficially because...

...Abstract The oil and gas industry has a tremendous need for the protection of assets during shipment and storage. Newer advances have allowed the use of the vapor corrosion inhibitor technology to be incorporated into temporary coatings which are designed to provide corrosion protection in extreme...

...Table 1 shows the material used for this research, experimental conditions, and the different techniques used for monitoring corrosion and analyzing specimens. The generic inhibitors used in these experiments were labelled K1 and K4; K1 has 24% TOFA/DETA imidazoline as the only active component...

..., corrosion inhibitor assessment methodology is introduced that accounts for the onset of corrosion inhibition during incubation time, that often is ignored when single corrosion measurement procedure is used. The robust analysis described in this paper uses a combination of open circuit potential...

... surface applied coatings can be costly to implement and maintain, and can become even more costly if they fail. Replacement of equipment can result in millions of dollars in losses - both in replacement cost and facility downtime. Incorporation of volatile corrosion inhibitor (VCI) systems is an effective...

...Abstract In oilfield applications, various divalent cations are present in field produced waters, e.g. Ca²⁺, Mg²⁺, Sr²⁺ and Ba²⁺. The interaction of these cations with phosphonate scale inhibitors (SI) is important both for scale inhibition and inhibitor...

...For the investigation of inhibitor efficiency, two water-soluble, oil dispersible inhibitors were chosen. The compositions of the inhibitors were taken from the safety data sheets. Tables 3 and 4 show the amounts of ingredients. Abstract An amine based CO2 corrosion inhibitors...
