The Formation of struvite Scale Formation and the Effect of As(V) and Hg(II) Impurities

Product Number: 51319-12942-SG

Author: Petros Koutsoukos

Publication Date: 2019

$20.00

Magnesium ammonium phosphate hexahydrate (MgNH4PO4·6H2O Struvite) scale deposits is often a serious operational problem in anaerobic treatment of municipal waste water and other industrial wastewaters. The kinetics of the nucleation and crystal growth at conditions simulating municipal wastewater was investigated in a 1L reactor at conditions of constant supersaturation at pΗ 9.50 25°C both in the absence and in the presence of As(V) and Hg(II) at concentration levels precluding the formation of insoluble salts of these impurities. Over the range of the relative supersaturation with respect to struvite investigated (σ=0.096-0.37) the presence of As(V) resulted in lower rates of crystal growth while the mechanism was the same in both cases i.e. surface diffusion controlled. The effect of As(V) concentration on the crystal growth rates of struvite was diminished as the supersaturation increased. The presence of As(V) at concentrations in the range 0.1-1 mM resulted in 90% reduction of the rates of crystal growth while induction times increased significantly. The presence of Hg(II) resulted in acceleration of the rates of crystal growth while no induction times were observed. In both cases equilibrium adsorption measurements showed that the effect of As(V) and Hg(II) is due to the interaction of these ions with the surface of the growing supercritical struvite nuclei.

The Futility and Folly of Seeking the Accelerated Corrosion Holy Grail

Product Number: 41215-885-SG

Author: Carl W. Reed, Kat Coronado

Publication Date: 2015

$20.00

Since the dawn of mankind, or at least since the advent of the very first accelerated corrosion cabinet, it has been the goal of coatings evaluators to develop an accelerated corrosion testing protocol which reflects the real world of corrosion in totality. There have been passionate arguments promoting one or another testing protocol while demonizing others, but that one protocol has yet to be developed to everyone’s satisfaction.

The Gas Fracking Boom: Expanded Opportunities for the Protective Coatings Industry

Product Number: 41214-857-SG

Author: E. Bud Senkowski

Publication Date: 2014

$20.00

A new era of natural gas exploration is spreading across the continental United States and Canada. Through a technique called hydraulic fracturing (fracking), huge deposits of oil shale, like the Marcellus and Utica deposits that extend from the Appalachians and into Canada, are now producing enough gas to meet North America’s needs for the next 14 years. The boom in gas exploration has opened up new markets for pipeline and joint coating materials to provide corrosion protection.

The Gender Gap: Impact on Innovation?

Product Number: 41212-679-SG

Author: Elizabeth Haslbeck, Suzanne Friedman

Publication Date: 2012

$20.00

Studies have shown that ensuring gender balance in the workforce and promoting high-performing women into executive positions improves the profitability and market strength of U.S. companies. Increasing the number of women studying and ultimately working in Science Technology Engineering and Math (STEM) jobs would increase innovation and the performance of teams in the workplace.

At this very moment the equipment, infrastructure and facilities of this nation and of the Department of Defense (DoD) are under attack by a known enemy. This enemy has the ability to work 24 hours a day, 365 days a year. The damage, degradation, and deterioration caused by this enemy doesn’t happen overnight; it usually happens over an extended period of time and is often visible to us during the process. That enemy is corrosion!

The History Of Hydrogen Induced Stress Cracking (HISC) Failures Of Duplex & Super Duplex Stainless Steels (DSS/ SDSS) Due To Cathodic Charging And The Potential For Improvement In HISC Resistance

Product Number: 51322-18070-SG

Author: Glenn Byrne, G. Warburton, R Francis

Publication Date: 2022

$20.00

As long ago as 1973, design codes1 considered the possibility of hydrogen embrittlement due to CP. Between 1986 and 1995^2-4 the failure of DSS fasteners subjected to CP were reported. These were associated with high ferrite levels in the steel (approximately 70%) combined with precipitation hardening at 475°C to give the high levels of strength desired for fastener applications. At the same time, the susceptibility of DSS welds to hydrogen embrittlement had been reported5. Just like the fastener failures, the hydrogen cracking of welds was associated with high ferrite levels (70%), highly restrained joints and in the case of welds, high levels of diffusible hydrogen.

The History of Protective Coating Use in- US Nuclear Power Plant

Product Number: 51218-165-SG

Author: Jon R. Cavallo, Bob Walcheski

Publication Date: 2018

$20.00

Since the inception of the US commercial nuclear power program in the 1950’s, criteria have existed for ensuring the satisfactory performance of reactor containment protective coatings over the life of the plant. These criteria have been modified and updated periodically to reflect improvement of the industry and regulatory experience and knowledge bases. This presentation reviews the development of the current qualification requirements for US commercial nuclear power plant reactor containment coatings.
