Abstract Previous studies of our group showed that Zn-Al-Mg hot-dip galvanized steel sheets have a superior corrosion resistance compared to conventional hot-dip galvanized steel sheets. This work especially focuses on the stability of this material at different pH values and the formation of corrosion products. There…
Abstract The objective of this research was to investigate the actual status of its problems, regional distribution and mitigation measures studies of black powder inside of Chinese long-distance natural gas pipelines. The information documented in this paper was analyzing basic information, operating parameters, gas…
Abstract This paper summarizes the structural materials used in light water reactors (LWRs), their historical degradation evolution vs. time, improvements and subsequent vulnerabilities discovered, and possible future degradation phenomena over long-term operation. Little was known about high temperature water environ…
Abstract During the transportation of wet gas, temperature gradient between the internals of the pipeline and the outside environment leads to the condensation of water vapor. Freshly condensed water is very corrosive and can lead to the so-called Top-of-the-Line Corrosion (TLC). However, a certain fraction of hydroca…
Abstract About 90% of the world's bioenergy is produced by burning renewable biomass fuels. Low-cost biomass fuels such as agricultural wastes typically contain more alkali metals and chlorine than conventional fuels. Although the efficiency of a boiler’s steam cycle can be increased by raising its maximum steam tempe…
Abstract A 2000-liter, large scale flow loop with 10 cm I.D. pipeline and three different test sections has been used over several years with the goal of understanding the mechanisms involved in H2S/CO2 corrosion environments. Mild steel from an API 5L X65 pipeline was used for the flush-mounted weight loss samples in…
Abstract The annulus of an unbonded flexible pipe contains armouring layers, which are typically made of carbon steel wires. The annulus is characterized by having a low ratio of free volume (V) to steel surface area (S). Typically the V/S ratio is below 0.1 ml/cm2. The free volume may be wetted with water and influen…
Abstract Top-of-the-Line (TOL) corrosion is a significant problem associated with the transportation of wet natural gas in the oil and gas industry. It has the potential to cost the industry millions of dollars every year through the replacement of affected pipelines and lost or deferred production. There is increasin…
Abstract Since its first application in the UK sector of the North Sea in the late 1980’s, THPS has established a “best-in-class” status for the control of problematic sulfate reducing bacteria (SRB) and the operational problems associated with their metabolic activity. This paper will review how THPS technology has b…
Abstract In the oil and gas industry, transportation of the hydrocarbons may involve high concentrations of CO2 and significant amounts of liquid water which will provide the electrolyte for the corrosion of mild steel to take place. The consequent damage can be in the form of general corrosion or localized – pitting…
Abstract The development of hydrocarbon gas fields which contain very high CO2 contents (up to 80 mol%) using carbon steel seems a difficult proposal and calls for the use of expensive corrosion resistant alloys. This would have the potential to render project development costs untenable. Unlike transportation and seq…
Direct graphene growth on insulating substrates is of great importance for graphene electronics. Limited accomplishments by using molecular beam epitaxy have been demonstrated on substrates of hexagonal symmetry. For comparison and further progress, we study the growth of graphitic carbon on cubic MgO substrates. Rama…
Abstract Soluble hyperbranched glycopolymers were prepared by copolymerization of glycan monomers with reversible addition‐fragmentation chain transfer polymerization (RAFT) inimers in a simple one‐pot reaction. Two novel RAFT inimers, 2‐(methacryloyloxy)ethyl 4‐cyano‐4‐(phenylcarbonothioylthio)pentanoate (MAE‐CPP) an…
Hexagonal, bullet-like ZnO microstructures and nanorod arrays have been prepared successfully by a simple hydrothermal method without surfactants. The structure and composition of the samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectrum (EDS), infr…
We report an epitaxial growth of graphene, including homo- and hetero-epitaxy on graphite and SiC substrates, at a temperature as low as ∼540 °C. This vapour-phase epitaxial growth, carried out in a remote plasma-enhanced chemical vapor deposition (RPECVD) system using methane as the carbon source, can yield large-are…
Abstract A study on effect of chemical treatment using maleic anhydride‐grafted polypropylene (MAPP) and 3‐aminopropyltiethoxysilane (3‐APE) was investigated. The performance of the MAPP and 3‐APE were investigated by means of torque development, mechanical properties, thermogravimetric analysis (TGA), differential sc…
Abstract The Pourbaix diagrams for an Fe-CO2-H2O system at elevated temperatures were constructed using thermodynamic theory and data and then correlated with observed CO2 corrosion phenomena of mild steel up to 250°C. In the range 80-150°C corrosion product layer formed and the surface analysis showed a mixture of cr…
Abstract Results from previous studies demonstrated that significant corrosion of carbon steel was observed when 1% SO2 impurity was contained in a supercritical CO2 phase in the presence of small amounts of water (650 ppm). Considering real situations for CO2 transportation pipelines, the effects of CO2 phase change,…
We describe a novel strategy for the fabrication of plasmonic nanopowders (dried gold nanoparticles) by using wet chemical nanoparticle synthesis, PEG-SH functionalization, and a standard freeze-drying technique. Our strategy is illustrated by successful fabrication of different plasmonic nanopowders, including gold n…
Abstract Over the past few years, under deposit corrosion (UDC) has been frequently cited by operators, corrosion engineers, failure forensic analysts, asset integrity authorities and Root Cause Analysis specialists as being a major player in different failures within the oil and gas operations. It has also been ident…
