Corrosion Inhibition Mechanism Study of a Novel Yellow Metal Corrosion Inhibitor

Product Number: 51319-12847-SG
Author: Xuejun Wang
Publication Date: 2019

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.

The efforts to lower automotive component weight to make cars more fuel efficient has increased the demand for aluminum alloys. In these applications, substantial amounts of heat are generated due to engine combustion, making it necessary to cool the engine systems. Metals in an engine application will rely on coolant to transfer heat. Corrosion behavior is another consideration for metals. Aluminum alloys, similar to the metals they are replacing, are sensitive to corrosion, especially in an aqueous alkaline environment.

A suitable acid package in matrix acidizing application is very important to the stimulation employed to improve the productivity of carbonate reservoirs. Typically, concentrated acids between 5 and 28 wt% are used and the most used mineral acid for carbonate acidizing treatment is hydrochloric acid (HCl) 1,2. A significant challenge of acidizing treatment is corrosion loss of metal tubulars due to the high reactivity of acid and metal, especially at high temperatures. Corrosion inhibitors are needed to reduce the corrosion loss of steel surface of facilities exposed in acidic environment.

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 of pipelines made of carbon steel and exposed to wet hydrocarbons containing CO2 and H2S is a common but serious problem encountered in petroleum industry and its occurrence causes enormousexpense due to production downtime, accidental injuries, and replacement costs. Control and prevent corrosion using chemical treatment (e.g. corrosion inhibitor injection) is one of the most cost-effective solutions and commonly practiced methods to prevent corrosion failures in pipelines in oil and gas industry. Generally speaking, the active corrosion inhibitor (CI) components in commercial CI packages are usually organic, nitrogen-based surfactants such as amines, imidazoline and its derivatives. Due to the amphiphilic nature of surfactants, a good fraction of the injected CI will inevitably go into the oil phase through partitioning and to the oil/water interface.

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.

Umbilical functionality is critical to the proper operation of subsea production systems to eliminate risks and downtime. The importance of preventing subsea operational issues has led to more stringent chemical quality requirements as the applications have gone deeper in depth, further from shores, and more demanding as far as Health, Safety & Environment are concerned.(1) Production chemicals such as corrosion inhibitors to provide protections for subsea systems from flow assurance to integrity management have become more demanding concerning product performance, stability, deliverability, and compatibility with the materials of construction. The present work describes various laboratory testing techniques used for certificating corrosion inhibitors designed for subsea applications via umbilical and deepwater applications.

CO2 is well recognized to be a major factor accelerating the corrosion process. When CO2 dissolves in water, it forms carbonic acid which is a weak acid and it dissociates only slightly to form bicarbonate ion followed by further dissociation to form carbonate ions (Figure 1). At pH levels lower than 5.5, the bicarbonate ions (HCO3-) are the main carbonic species in solution.

Corrosion inhibitors provide a critical barrier to internal corrosion, presenting the most cost-effective form of mitigation and enabling operators to use carbon steel where it would otherwise be impractical. The correct selection and validation of inhibitors is essential to ensure successful field deployment, providing safe and reliable operation. However, the selection and optimization of a corrosion inhibitor for a particular field application is not trivial.
