Corrosion Inhibition Mechanism Study of a Novel Yellow Metal Corrosion Inhibitor

Product Number: 51319-12847-SG

Author: Xuejun Wang

Publication Date: 2019

$20.00

The corrosion inhibition mechanism of a new yellow metal corrosion inhibitor was studied using multiple characterization techniques including ellipsometry white light interferometry (WLI) grazing incidence reflection absorption Fourier transform infrared (GIRA-FTIR) spectroscopy X-ray photoelectron spectroscopy (XPS) electrochemical impedance spectroscopy (EIS) and high-performance liquid chromatography (HPLC). Compared to traditional azole molecules the novel yellow metal corrosion inhibitor develops a stimuli-responsive film which would reduce the impact of high levels of halogen on the corrosion of copper and copper alloy surfaces. A tentative structural model describing the improved halogen resistance of copper and copper alloy in the novel yellow metal corrosion inhibitor solution is proposed.

Corrosion Inhibition of Equipment Under Hydrstatic Test – Experience From Algeria

Product Number: 51319-12848-SG

Hydrostatic test is essential step in integrity management of different pressure equipment such as vessels piping valves etc. In spite of its corrosive characteristics industries continue to use water for hydrotesting purpose which then may cause various corrosion rates in relation with time of exposure to hydrostatic test lay down period time of retained water after drainage origin of water level of chlorides oxygen content etc… Each case speaks for itself yet after several projects carried-out in Algeria with selected VCI inhibitor a database of water corrosivities and optimum dosage rates has been gathered.Key words: corrosion hydrostatic test water corrosivity inhibitors dosage rate

Corrosion Inhibitor Performance under High Temperature / High Salinity Sweet Conditions

Product Number: 51319-12756-SG

It is well known that the inhibitor efficiency is encumbered by many variables such as temperature pressure pH flow speed and chemical composition of the production fluid. Salt content of formation water varies dependent on the location. Sometimes the salinity shows more than 10% by weight.The performance of several corrosion inhibitors was evaluated with an electrochemical measurement namely Liner Polarization Resistance (LPR) and weight loss coupons in autoclaves. Test solution was synthetic brines with Total Dissolved Solids (TDS) up to 17% by weight NaCl in this study. The test solution was aerated with CO2 at ambient temperature and pressure before testing between 60 and 100ºC.The inhibitors evaluated here had the temperature tolerance up to 100ºC. Corrosion inhibitors performed at low temperature better than high temperature condition. But some of them showed poor inhibitor efficiency in case of pre-corrosion with high salinity at high temperature condition. This study also confirmed the validity of ILSS (Inhibitor Likelihood Success Score) introduced by Crossland et al. and provided a useful information for inhibitor selection for pipelines in various field conditions.Several set up with/without pre-corrosion step was done to confirm the associated impact of corrosion testing procedure on the overall performance of the corrosion inhibitors. It seems that high salinity affects the inhibitor absorption competing with corrosion product. The pre-corrosion test is required step for a qualification of corrosion inhibitors for a high salinity field.

Corrosion Inhibitors for Carbon Steels Exposed to Aqueous CO2

Product Number: 51319-13184-SG

Author: Zineb Belarbi

Publication Date: 2019

$20.00

CO2 corrosion mitigation is a challenge in the oil and gas industry. In order to decrease the severity of CO2 corrosion of carbon steel pipelines and equipment different mitigation practices are recommended. One such strategy is the application of surface active chemical inhibitors. The objective of this study was to evaluate the inhibition effectiveness of thioglycolic acid 2-mercaptoethanol and decanethiol in a CO2-saturated aqueous electrolyte (1 wt.% NaCl). The inhibition properties of corrosion inhibitor were evaluated by electrochemical measurements (linear polarization resistance (LPR) and electrochemical impedance spectroscopy (EIS)) and the steel surface characterized by scanning electron microscopy (SEM). In addition surface characterization of adsorbed decanethiol molecules on carbon steel was performed using X-ray photoelectron spectroscopy (XPS). The obtained data show that decanethiol successfully prevents corrosion of carbon steels in a CO2 environment. An inhibition mechanism was also proposed based on adsorption characteristics and film formation.

Corrosion continues to be a threat to the petroleum industry. It risks people’s lives, assets integrity and the environment. These risks are mitigated by different means such as selection of appropriate materials, chemical treatment, cathodic protection, protective coatings, and process control. One of the most common corrosion control measures is the use of corrosion inhibitors. This is a cost-effective option that can be applied to upstream, mid-stream and downstream facilities. This has driven the research institutes and the chemical manufacturers to invest on developing corrosion inhibitor chemistries for field-specific applications. In spite of all the efforts being put, there are still many important aspects about corrosion inhibition treatment that need to be researched for a better understanding of the chemicals’ performance, monitoring, laboratory testing, and field application. This paper highlights knowledge gaps to invite focused research to help bridging the gaps between operators, research institutes and developing companies. These gaps are classified in four main areas: Field Monitoring, Facility Design, Laboratory Testing, and Simulation & Prediction.
