Resumen

Carbon steel (CS) is the most commonly used material for equipment and pipes in the oil production processes. However, presence of water/salts and carbon dioxide, among other gases, in the oil is a serious problem due to increased corrosion rate of the material. The most common way of mitigating this problem is by using corrosion inhibitors. However, many common corrosion inhibitors that are in use today are health hazards. Therefore, there is a need to develop more environmentally compatible and biodegradable corrosion inhibitors. Bioorganic and naturally occurring molecules, such as amino ac

Resumen

The goal of this thesis is to probe the functionality of 2-mercaptobenzimidazole (MBI) as corrosion inhibitor of carbon-steel in both strong and weak aqueous acidic solutions (HCl and H2CO3). To achieve this target electrochemical techniques have been employed, in combination with substrate analysis. Concerning aqueous HCl media, results demonstrate that MBI is an effective corrosion inhibitor, functioning essentially equally well in 1 M, 0.1 M, and 0.01 M HCl concentrations. X-ray photoelectron spectra suggest that MBI is typically bound to the surface in two tautomeric forms (thione and thio

Resumen

The deposition of hydrate and corrosion in the pipeline remain a major challenge in the petroleum industry. Internal corrosion slows and decreases the production of oil and gas when associated with free water and reacts with organic acid. Experiments had shown that the corrosion products (ferrous and anhydrous ions) combine together to form a precipitate on iron surface that are porous and non-protective. To prevent these occurrence, Mono-Ethylene glycol (MEG) is been utilized in the pipeline as an antifreeze and anti-corrosion agent. It has been observed that the MEG need to be separated from

Corrosion within the oil and gas sector is an ongoing concern for operators. The challenging nature of extraction and processing fluids is an unavoidable cause of severe metallic corrosion. With modern emphasis on health, safety and the environment, the case for managing corrosion has become an imperative agenda. Whilst new and more effective methods of mitigation are key, an interim solution is improving the value of current methods. A literature survey carried out within this project has revealed CO2 corrosion as contributing to most corrosion related failures within the industry. The corros

Resumen

Corrosion of metallic materials is a natural process, and our study shows that even in an alkaline environment severe corrosion may occur on a carbon steel surface. While corrosion cannot be stopped it can be retarded. Many of the traditional anti-corrosion approaches such as the chromate process are effective but hazardous to the environment and human health. Mefp-1, a protein derived from blue mussel byssus, is well known for its extraordinary adhesion and film forming properties. Moreover, it has been reported that Mefp-1 confers a certain corrosion protection for stainless steel. All these

Carbon dioxide and hydrogen sulphide pitting related failures are a prime concern in oil and gas internal pipelines. Often, these types of failure have a great impact on safety and environmental matters and can cause severe financial consequences to the operator. Chemical inhibitors have been used to provide effective protection for the asset whether it is due to localised corrosion or general corrosion. More often than not, the operating conditions determine the type of corrosion product film produced on the carbon steel and in tum influence the type of corrosion inhibitor to provide effectiv

Resumen

Pitting corrosion is one of the most destructive types of metal loss. The purpose of this study was to investigate the evolution, or in other words, the propagation, of a single pit in carbon steel after the initiation stage. In view of the chemical and electrochemical reactions inside a single pit in carbon steel, a two dimensional model that allows the prediction of pit evolution was developed. Eleven species in aqueous sodium chloride solution and two neutral complexes were considered in the model. Given that the active-passive transition of a metal is a key phenomenon in pitting, the equat

The aim of the research in this thesis was to study how environmentally friendly corrosion inhibitors for cooling water systems might be developed and used. Firstly, reduced toxicity inorganic corrosion inhibitors (i.e. nitrite/molybdate) were considered. Secondly, non-toxic inhibitors based on mono and di-basic salts of carboxylic acids were studied systematically as a function of carbon chain length. For nitrite inhibitor alone, a concentration of 7 mM NaNO2 was effective to inhibit carbon steel in chloride media of 10 mM NaCl, while 10 mM nitrite was needed in sulphate media of 3.66 mM Na2S

Copper corrosion and its inhibition are often associated with the presence of oxide films. Several studies have demonstrated that copper oxide films, which are normal corrosion products, protect copper substrate from further corrosion. However, little work has been carried out on the chemical formation of copper oxide films. On the other hand, the development of new polymer coatings is needed for corrosion prevention in aggressive environment. Although interest in the use of polypyrrole films for corrosion prevention has arisen recently, no successful utilisation of the polymer for control of

This paper deals with alternating current (AC) corrosion of low alloy carbon steel in 3.5 wt% NaCl electrolyte. Accelerated corrosion rates have been reported when exposed to AC and the corrosion mechanism is not well understood. Electrical heating of subsea pipelines, applied to avoid hydrate formation and waxing of multiphase hydrocarbon well streams has made this topic increasingly relevant in recent years. To study the effect of AC on corrosion rates, weight loss experiments under a wide range of experimental conditions were performed. Results show that AC strongly influence corrosion kine

Resumen

Surfaces of low carbon steel sheet were modified by exposure to highly caustic aqueous solutions containing either chromium or aluminum cations. Corrosion resistances of such surfaces were compared with that of steel surfaces exposed to plain caustic aqueous solution. In all cases a highly uniform, black coating having a spinel structure similar to magnetite (Fe3O4) was obtained. The coated steel surfaces were characterized using X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), and Fourier transform infrared spectrophotometry (F
