...It should be noted that at equilibrium, dθ/dt = 0, then Equation (3) reduces to the steady-state/equilibrium isotherm representation often used in corrosion inhibitor assessment, namely, (4) K L = k a k d = 1 C θ 1 − θ Which in turn can be rearranged...

...Abstract Corrosion inhibitors are widely used across the oil and gas industry to protect valuable infrastructure and manage corrosion issues. It is critical these chemicals are applied at a suitable dose: too much chemical can cause emulsion problems and increase OPEX, while too little chemical...

... into service leading to potentially severe internal corrosion risk due to residual water and associated corrosion factors such as oxygen, salts, solids and microbes. Such risk can be reduced by conducting a batch chemical treatment with corrosion inhibitors and biocide. There are several key challenges...

...EXPERIMENTAL PROCEDURE Corrosion Inhibitor Two types of corrosion inhibitor were examined. Inhibitor A is better in adsorption performance in a static environment such as batch treatment in a production tubing or a pipeline. Inhibitor B shows better inhibitor efficiency under a high shear stress...

... specimens were wet ground with #600 SiC sandpaper, thoroughly degreased ultrasonically in acetone or ethanol. Abstract Duplex stainless steel (DSS) tubing is known to suffer the selective corrosion in acidizing operation. This study considers the effect of additives to corrosion inhibitor (CI) for DSS...

...RC testing was conducted in the following sequence and in accordance with ASTM G184 ⁷ guidelines. ABSTRACT High pressure, high temperature (HPHT) corrosion in sour conditions is a major concern in oil and gas production. Here, the selection of corrosion inhibitor is a significant...

... operations. Often the scale and corrosion inhibitors are used simultaneously. Dual-functional combo products containing both inhibitors have also been developed and applied. ^{1 , 2} Corrosion inhibitors adhere to metal surface and create a continuous layer between the metal and water, thus reducing...

... flowlines to a new platform. In order to manage corrosion, the project corrosion monitoring objective was to flag any short fall in corrosion inhibitor injection rates to minimise internal corrosion in the ten subsea infield flowlines and to confirm the corrosion inhibitor is working. The timeline...

..., though not banned yet, have been classified as Substances of Very High Concern (SVHC) under the EU REACH regulations. Because of these drawbacks and increasing environmental regulations, new non-toxic corrosion inhibitors are needed that can provide excellent corrosion inhibition, meet strict discharge...

... for hydrate control, and to facilitate the delivery of the corrosion inhibitor, chemical is injected in combination with the glycol. Mitigation of corrosion in the Laggan-Tormore multiphase pipelines presented several challenges. The glycol used in the field is recycled via a regeneration unit. Consequently...

...Abstract Systems such as pipes, heat exchangers, and storage tanks are subject to hydrostatic testing after fabrication. Corrosion inhibitors may be added to the hydrostatic test solution to provide corrosion protection prior to the installation and use of these systems. Effectiveness...

... and oxygen in diluents have the potential to cause corrosion in the pipeline. In addition, low density and viscosity of the diluent facilitate solid settling, raising the risk of under deposit corrosion. These potential corrosion risks are mitigated by continuous application of a corrosion inhibitor...
