Study On Elemental Sulfur Formation From Black Powder Deposits

Product Number: 51322-17678-SG

Author: Yousef Khuraibut

Publication Date: 2022

$20.00

Black Powder is a phenomenon that all oil and gas companies are facing and presenting a variety of problems in associated processing equipment and pipelines, such as flow inefficiency, product contamination, wear, plugging and under deposit corrosion, among others. Another major concern is the possible formation of elemental Sulfur (S8), which could be produced as a by-product of oxidation of iron sulfides. It also can be produced from H₂S dissociation at elevated temperatures or by microbiological reactions, involving the reduction of sulfate.

Surface And Defect Preparation Using Atmospheric Plasma For Non-Metallic Pipe Repair

Product Number: 51322-18175-SG

Author: Ahmed Hassanin, Chris Alexander, Jeffrey Piascik, Peter Yancey, Glenn Astolfi, Jeff Pavelka

Publication Date: 2022

$20.00

Composite repair systems’ performance relies heavily on the levels of adhesion between the initial layer of the composite system and the substrate. Enhanced adhesion translates to improved performance of the composite system since better bonding (whether mechanical or chemical) enhances the load transfer from the substrate to the composite layers as well as limit the porosity that would allow liquid or gas molecules to flow through. The aim of this study was to prove quantitatively how the APS atmospheric plasma surface preparation can improve the performance of composite repair systems whether on leaking or nonleaking defects.

With the increased pollution and energy demand, industries are shifting towards cleaner and greener power generation source. Geothermal energy, where energy is derived from the sub-surface of earth, is an excellent and continuous source of energy. Despite having the potential of providing cleaner energy, there is a huge gap between the theoretical potential of geothermal power plants and their practical applications. Some of the major reasons are high power generation cost and poor efficiency of the plant.

Sustainable Coatings For Above Ground Storage Tanks

Product Number: 51322-18057-SG

Author: M. Gagné, J. Weber

Publication Date: 2022

Controlling corrosion of steel is expensive. The direct costs of corrosion maintenance are estimated to be over 3% of GDP every year.¹ Metallic zinc coatings provide very effective corrosion protection for steel by acting first as a barrier coating, keeping corrosive elements away from the steel, and secondly as a sacrificial anode.² Should the zinc coating be compromised, accidentally by a scratch or on purpose with a drilled hole, the zinc will provide anodic protection to the exposed steel. Metallic zinc coatings can be pure zinc or zinc-based alloys and will be referred to generically as zinc coatings in the paper. Zinc coatings can be efficiently applied by thermal spraying, which involves projecting particles of semi-molten zinc onto the surface of the steel using compressed air. With thermal sprayed zinc (TSZ) coatings, there is no size limitation to the part to be coated, and the technology is fully portable, allowing easy field applications.

Tank Waste And Ground Water Effects On The Corrosion Susceptibility Of The Secondary Liner Of Hanford Double-Shell Tanks

Product Number: 51322-17550-SG

Author: Sheewa Xihuahe Feng, Jason S. Page

Publication Date: 2022

$20.00

The nuclear waste at the Hanford Site is currently stored in 131 single-shell tanks and 27 double-shell tanks (DSTs). When the primary liner in Tank 241-AY-102 (AY-102) failed, the secondary liner became the principal barrier of the tank, and leaked waste interacted with the refractory foundation beneath the primary liner. The high caustic concentration of the tank waste could have reacted with the tank refractory, lowering the pH and leading to increased corrosion rates of the annulus tank steel. The extent of change would depend on the waste volume to surface area ratio and other factors.

The AA2024/CFRP Galvanic Couple Under A Dynamic Electrolyte Drop

The gap between fully immersed and ultra-thin film electrochemical measurements is wide, which suggests that the two conditions are independent of one another. There is a lot of work describing experiments, results, and trends regarding completely immersed electrochemical tests. However, in corrosion tests under thin electrolyte films, the information is not so abundant. A classical three-electrode cell used in conventional electrochemical tests cannot easily be scaled for immersion in electrolytes of micron thickness.

The Change Of Corrosion Inhibition Behavior Of Tetradecyl Phosphate Ester At Elevated Temperatures

Product Number: 51322-18053-SG

Organic corrosion inhibitors (CIs) are widely employed in the oil and gas industry to protect carbon steel pipelines against internal corrosion. The high inhibition efficiency of organic CIs at extremely low concentration can be attributed to their amphiphilic molecular structures. This structure enables the formation of self-assembled films that act against corrosion via the adsorption of their hydrophilic head group on the steel substrate and the repellence of aqueous corrosive species by their hydrophobic tail. Consequently, any factors affecting the film formation of organic CIs could lead to changes in inhibition behaviors.

The Development Of Environmentally Acceptable Corrosion Inhibitors For Sour Applications

The decomposition process of ancient marine species in the seabed for millions of years coupled with the presence of specific geological conditions such as high pressures and temperatures led to the formation of what is known today as fossil fuels. For this reason, they can be found either on the earth's surface where ancient seas were located or beneath the seabed. Considering that the ocean covers three-quarters of the Earth's surface the offshore oil and natural gas exploration entail an enormous economic and strategic benefit.¹

The Effect Of Strain On Surface Residual Stress In Alloy 600 Tensile Specimens

Product Number: ED22-17258-SG

Author: Karyn Cooper, William Brayshaw, Mark Chatterton, Sonya Pemberton, Stuart Medway, Jennifer Borg

Publication Date: 2022

$20.00

Nickel based Alloy 600 is used within the nuclear industry in structural components due to its good mechanical properties and general corrosion resistance, however upon exposure to primary water environments at elevated temperatures it can be affected by Primary Water Stress Corrosion Cracking (PWSCC). Nickel Based Alloy (NBA) susceptibility to PWSCC is dependent on a number of factors that include material type, condition and microstructure, as well as fabrication method, and can be investigated by uniaxial initiation testing in a primary water environment, where specimens are held at constant load under an elevated temperature.

Maintaining the integrity of oilfield equipment is essential to its safe operation and to maximize the efficiency of production. The integrity of oilfield equipment can rely on material selection and control of conditions, however, it is commonly maintained by the applications of chemical corrosion inhibitors (CI). Prior to use, these chemicals must be shown to perform as desired under the field conditions in question. To achieve this, chemicals are often evaluated using robust laboratory-based screening studies to identify potential candidates.

The Effects Of Different Blast Abrasives On The Performance Of Liquid-Applied Epoxy Pipeline Coatings

Product Number: 51322-17806-SG

Author: Haralampos Tsaprailis, Shan (Sherry) Rao

Publication Date: 2022

$20.00

Proper surface preparation to create sufficient adhesion of a coating over the substrate is fundamentally important in the long-life performance of a protective coating. Abrasive blast cleaning provides a fast and well-established method of surface preparation, which utilizes energy generated by an air supply to deliver a mass of abrasive particles at certain speeds and volumes to impact the steel resulting in a cleaned surface. The method not only cleans the surface to remove rust, scale, paint, and similar contaminations, but also roughens the surface to produce mechanical and chemical adhesion for a coating. Therefore, abrasive blasting is the preferred method for preparing steel for the application of high-performance coatings and routinely used for achieving the required surface conditions prior to a coating work.
