The Hanford Site stores over 50 million gallons (190 million liters) of legacy nuclear process waste that was generated from plutonium separations and waste management processes. This waste, in the form of supernatant liquids, saltcakes, and sludges is contained in large underground storage tanks, up to a million gallons (3.78 million liters) in capacity and lined with carbon steel. The waste was made highly alkaline to ensure passivation of the carbon steel, but it also contains nitrate, in high concentrations, along with fluoride and chloride that poses risks for stress corrosion cracking and pitting corrosion.

Permeability: an in Depth Look at the ASTM’s When the Data can be Important, and When the Information is Irrelevant

Product Number: 51220-285-SG

Author: John Sierzega

Publication Date: 2020

$20.00

Often coatings are judged by certain criteria especially when it comes to immersion service. One of the criteria used to evaluate these coatings is permeability, which is often misunderstood. With 2 ASTM test methods, each with multiple methods and ways to report the results, you may get so much conflicting information that none of the information permeates into your brain in an understandable way.

Duplex stainless steels (DSS) are widely used as structural alloys in marine and energy industries because of their excellent combination of mechanical properties and corrosion resistance. In light water reactor (LWR) power plants, these alloys find their applications in piping and internal structural components. With a currently designed lifetime of 40 years, these DSS components show little degradation in their mechanical properties. However, most current and future nuclear power plants are expected to operate beyond 60 years. This prolonged service period challenges the integrity of materials and components in the reactor. DSS component lifetime in the reactor is subjected to elevated temperatures, internal pressures, and corrosive environments.

Phenylalanine derived Zwitterion as Green Corrosion Inhibitor for Mild Steel in 1M HCl: Electrochemical

Product Number: 51319-12800-SG

Author: Jiyaul Haque

Publication Date: 2019

$20.00

The Phenylalanine based corrosion inhibitor 13-bis(1-carboxy-2-phenylethyl)-5-methyl-1H-imidazol-3-ium (IP) were synthesized by the condensation of phenylalanine glyoxal and formaldehyde and characterized by the FTIR and NMR spectroscopy. The corrosion inhibition performance of synthesized inhibitor was studied by electrochemical impedance spectroscopy (EIS) potentiodynamic polarization (PDP) Surface and DFT methods. The results show the studied IP is an effective inhibitor showed the maximum inhibition efficiency of 96.08% at concentration 200ppm. The results of PDP study revealed that IP act as mixed type inhibitor. The results of EIS studies showed that IP inhibits the mild steel corrosion through adsorption mechanism. The adsorption of synthesized phenylalanine derived Zwitterion on the mild steel surface was followed the Langmuir adsorption isotherm. The formation of inhibitor film on mild steel surface was confirmed by the scanning electron microscope (SEM) and energy-dispersive X-ray spectroscopy (EDX). The quantum chemical parameters were used to study the reactivity of IP inhibitor with iron surface. An inhibitor adsorption model is proposed.

PHMSA Gas Pipeline Mega Rule

Product Number: 51324-20895-SG

Author: Sasan M Hosein

Publication Date: 2024

$40.00

The Pipeline and Hazardous Materials Safety Administration (“PHMSA”) recently released the final rule known as the “Mega Rule” which includes a set of regulations designed to improve pipeline safety by reducing the frequency of pipeline failures. The intent of the rule is to address lessons learned following the Pacific Gas and Electric Company rupture and release in San Bruno, California, in September 2010. On September 9, 2010, a natural gas pipeline owned by Pacific Gas & Electric (PG&E) exploded in San Bruno, CA. creating a fire that killed eight people, destroyed more than 100 homes and cost $2.8 billion. An investigation by the National Transportation Safety Board (NTSB) found that PG&E had a faulty integrity management (IM) system that failed to detect a defective section of the pipeline resulting in the devastating explosion. The PG&E incident spurred action from the Pipeline and Hazardous Materials Safety Administration (PHMSA) to revise the existing Federal Pipeline Safety Regulations (FPSR) to improve the safety of onshore gas transmission pipelines. These revisions are known as the Mega Rule. This final rule responds to the incident by extending existing design, operational and maintenance, and reporting requirements under the Federal Pipeline Safety Regulations to onshore natural gas transmission pipelines and gathering pipelines in rural areas. The Mega Rule is a sweeping set of regulations comprised of three parts: • Part 1 focuses on the safety of gas transmission pipelines. • Part 2 introduces new guidelines about IM, updated requirements for high consequence areas (HCAs) and expectations for operators following extreme weather events and natural disasters. • Part 3 expands certain safety requirements to all onshore gas gathering pipelines.

PHMSA Regulation on HDD Coating and PRCI Guidance

Product Number: 51319-12904-SG

Author: Ron Raphoon

Publication Date: 2019

$20.00

Pipeline Owners use the HDD installation method primarily in high consequence areas. The pipelines are thrust into the ground in one of the harshest possible manners which ultimately puts the protective coatings to the test. The manner that the Pipelines are coated and tested is governed by PHMSA. This presentation will address what the current regulations are and their effectiveness. I will additionally inform the audience about recent testing done by PRCI to evaluate the effectiveness of post installation coating inspection. To further the understanding we will review the newest guidance being supplied by PRCI and the upcoming changes to the regulations that are being put forth by PHMSA. The objective of this presentation is to educate pipeline owners contractors and coating applicators about the changes that have arisen in the past few years with regard to pipeline coating protection in these very sensitive environments so that we can better protect the community from incidents similar to what we saw in San Bruno or the leaks we've recently seen under The Great Lakes.

Phosphate Esters Inhibitors in Naphthenic Acid Corrosion – An Experimental Evaluation

Product Number: 51319-13491-SG

Author: Gheorghe Bota

Publication Date: 2019

$20.00

Crude oils with a total acid number (TAN) higher than 0.5 are highly corrosive at temperatures between 400 and 700°F typical to atmospheric and vacuum distillations of oil refineries. This destructive effect of naphthenic acids (NAP) is enhanced by the presence of hydrogen sulfide generated in thermal decomposition of sulfur compounds also contained in crude oils. The efforts of mitigating the acidic crudes corrosive effects include blending such oils with crudes of lower acids content neutralization or removal of naphthenic acids from oils and the use of corrosion inhibitors. Most commonly used inhibitors for mitigating the NAP corrosion are based on organic polysulfides or on phosphate esters. Two phosphate esters corrosion inhibitors were evaluated in laboratory experiments using a specific testing procedure – “pretreatment - challenge”. This experimental method evaluates the naphthenic corrosive effects at high temperature on scales formed from crude factions on metal surfaces. Adding the inhibitors to the crude fractions improved the protective properties of scales formed under such conditions. The corrosive effect of naphthenic acid was evaluated by sample weight loss. The scales formed on these samples were investigated using scanning electron microscopy (SEM) and transmission electron microscopy (TEM) coupled with energy dispersive spectroscopy (EDS).Keywords: phosphate esters corrosion inhibitors naphthenic acids high temperature

Ph-Responsive Copolymers As Silica Scale Inhibitors

Product Number: 51322-17703-SG

Author: Georgia Skordalou, Konstantinos D. Demadis

Publication Date: 2022

Silicon is an important element of our Planet’s crust, which is transferred into water streams through dissolution.1 Hence, it is usually found as water-soluble silicate or colloidal silica in natural surface waters (sea, rivers, lakes), or underground waters. When such water is used for industrial purposes (eg. industrial cooling), silicate can enter the operating system and can pose a threat to its proper operation. The main reason is the solubility of amorphous silica, a product of the silicate polycondensation process.
