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

Product Number: 51322-17550-SG

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 Effect of CO2 Partial Pressure on the Formation and Protective Characteristics of Iron Carbonate Corrosion Products

This study investigates the effect of carbon dioxide (CO2) partial pressure on the rate of formation and the protective characteristics of iron carbonate (FeCO3) corrosion product layers on X65 carbon steel in aqueous systems. Autoclave corrosion tests were performed at 80 °C in CO2-saturated 3 wt.% sodium chloride solution at partial pressures from 5.5 to 15.5 bar. Linear polarization resistance and electrochemical impedance spectroscopy electrochemical methods were utilized to provide insight into the stages of corrosion product layer development. Analysis of the electrochemical response under each condition revealed key, distinguishable stages associated with the development of an FeCO3 layer as its role transitions from predominantly blocking steel active sites, to ultimately providing additional corrosion suppression through formation of a diffusion barrier. It was found that at higher CO2 partial pressures, the onset of diffusion control was accelerated, but the overall corrosion rate was greater than at lower pressures.

The Hanford Nuclear Reservation contains radioactive and chemically hazardous wastes arising mostly from weapons production, beginning with World War II and continuing through the Cold War. The wastes are stored in 177 carbon steel underground storage tanks, of which 149 are single-shell tanks (SSTs) and the remaining are double-shell tanks (DSTs). The U.S. Department of Energy, Office of River Protection is responsible for retrieving the tank wastes, treating them in order to encapsulate them in glass logs, and then permanently closing the tanks and associated facilities.

The Influence Of Oxygen On Protective Iron Carbonate Scales Formed On Carbon Steel In CO2 Environments At Near-Neutral Ph

Product Number: 51322-17899-SG

Author: Pedro Netto da Silva, Gaute Svenningsen, Arne Dugstad, José Antônio da Cunha Ponciano Gomes

Publication Date: 2022

High strength carbon steel tensile wires confined in the annulus of flexible pipes might experience corrosion when the annulus is flooded with water, either due to outer sheath breaches or to condensation of water molecules permeating from the bore through the inner sheath. Carbon dioxide (CO₂) molecules may also permeate from the bore and reach the annulus, where it dissolves into water to form carbonic acid (H₂CO₃).

The Performance of Phenolic Epoxy Coating after Thermal Exposure for Corrosion Protection in Marine Environments

Product Number: 51323-19046-SG

Author: S. Ahmed, T. Becker, Y. Hou, K. Lepkova, T. Pojtanabuntoeng

Publication Date: 2023

Organic coating is the most widely used method of corrosion protection. its corrosion protective abilities depend on physical, chemical and mechanical properties including adhesion to a substrate and essential barrier properties against corrosive species, such as water and oxygen. The durability of corrosion protection coatings is evaluated based on their effectiveness in providing long-term protection to metallic substrates when these materials are exposed to aggressive corrosion environments.

Two-Way Application of Corrosion Inhibitor in Gas and Condensate Field

A fit for purpose qualification of new corrosion inhibitors was carried out for in a gas and condensate field. The depth of production well is 4,500 m and the bottom hole temperature and pressure are 180ºC and 50 MPa respectively. The methodology and result of the inhibitor evaluation under a sweet condition was summarized. Two brands of corrosion inhibitors had been used each for production tubing and flowline in the field. New corrosion inhibitors were evaluated for the both applications. The corrosion inhibitor efficiency for high shear service and the adhesion tendency were evaluated with a rotating cage autoclave and a dip and drip experiment respectively. In order to evaluate the tendency of emulsion forming, oil, brine and an inhibitor were poured into a centrifuge tube and it was shaken intensely. Gas chromatograph - mass spectrometer (GC-MS) and Fourier transform infrared spectroscopy (FT-IR) were studied to measure the residual amount of inhibitor. Finally, the field trial was conducted with a new inhibitor. The new inhibitor was adopted successfully for the both services. The risk of emulsion forming became lower because the mixing of two brands of inhibitors was avoided. Reducing the number of the chemicals contributed to reduction of the operation cost too.

Understanding Carbon Steel Corrosion and Inhibition in Deep Pit-Like Features Under Thick Deposit Layers

Product Number: 51323-19284-SG

Publication Date: 2023

Corrosion of carbon steel is the most prominent reason for pipeline failure in a range of industries, from oil and gas transportation to water treatment facilities and nuclear waste storage. Under-deposit corrosion occurs in low fluid flow rate environments, when particulate matter (such as sand and clay) settles on the bottom of transportation pipelines. The presence of deposits results in a diffusion barrier, which significantly alters interfacial solution chemistry compared with that of the bulk.

Understanding the Corrosion Performance and Mechanism of Stainless and Carbon Steels in Different Storage and Transportation of Pyrolysis Oil Environments

This study assessed the suitability of two candidate materials for use in fast pyrolysis reactors and their core components. An immersion test conducted at temperatures of 60 °C and 80 °C over a 7- day period revealed significant corrosion in carbon steel A516-70, with corrosion rates reaching up to 6.24 mm/year. In contrast, UNS S32205 displayed impressive resistance to corrosion, even at 80 °C. Fe2O3 have been identified as the major corrosion products on A516-70, chromium oxides and spinel oxides were found on UNS S32205. The primary corrosive agents were identified as organic acids present in the pyrolysis oil, owing to the oil's high total acidic number and low pH value. Ongoing microscopic characterizations aim to provide a more comprehensive understanding of the underlying corrosion mechanisms.
