Pitting Factor Criteria for Localized Corrosion Inhibition of Liquid Radioactive Waste Stored in Han

Product Number: 51319-13430-SG

Author: Pavan Shukla

Publication Date: 2019

$20.00

Liquid radioactive waste stored in carbon steel made double shell tanks (DSTs) at Hanford have a comprehensive chemistry control program to prevent stress corrosion cracking (SCC) and other types of localized corrosion. Since waste retrieval and additions are to be expected to manage the waste into vitrification it is desirable to specify borderline conditions to prevent any susceptibility to pitting corrosion. Currently the chemistry control program inhibits localized corrosion due to nitrate concentrations using sodium hydroxide to raise pH over 12. However future streams may increase the concentration of aggressive species (e.g. chloride fluoride sulfate) and may decrease the pH of waste to 10. Using cyclic polarization potentiodynamic (CPP) the chemistry control program was optimized by designing a pitting factor using statistical analysis. Additionally immersion tests were performed to measure open circuit potential (OCP) and weight change corrosion rates for partially and completely immersed coupons. Borderline conditions determined by the pitting factor will be studied to provide limits for the chemistry control program.

Plant and Circuit Wide CCD/IOW Implementation Process

Product Number: 51319-13068-SG

Author: Brian Jack

Publication Date: 2019

$20.00

API 970/584 (Corrosion Control Documents/Integrity Operating Windows) are becoming a valuable resource in a Refinery Mechanical Integrity Program. The ability to usefully summarize unit Corrosion Loops and documentation of Damage Mechanisms is critical for Risk Based Inspections. When overlaid with susceptibility to both normal and process upsets conditions this becomes a benchmark for improvements in plant reliability programs.This paper will summarize both a Plant wide and a Fleet wide approach toward this process. One will be an orderly progression for a single Plant as part of a robust Mechanical Integrity program. A second Owner-User implementation of this process with a focus on a few typical refining units in same at multiple sites and on a pilot basis using multiple vendors to implement this project in a staged program.

Plasma Coating Removal: a Safety and Industrial Hygiene Analysis

Product Number: 51220-302-SG

Author: Moreau Yannick

Publication Date: 2020

$20.00

The Atmospheric Plasma Coating Removal (APCR) process provides a unique new way to quickly and safely remove the toughest industrial coatings. As with any new process a thorough examination of the possible risks to the end users and the environment is critical. APS hired an environmental testing facility to conduct a series of experiments and provide an assessment of noise, dust, and select chemicals to determine the safety of the APCR process.

Plural-Component Material Application Does Not Have to be Difficult

Product Number: 41213-758-SG

Author: Brian Ketel

Publication Date: 2013

$20.00

With modern advances in technology and materials, application equipment for two-part protective coatings has become easier to use. The benefits of using plural-component equipment far outweigh the risks. In today’s competitive market, plural-component sprayers provide the reliability and quality necessary to get work done and also provide the profit potential to help a business stay ahead of the competition.

Polyasparartic Ester Finish Coats - A New Generation

Product Number: 41208-440-SG

Author: Mike O’Donoghue, Ron Garrett, V.J. Datta, Justin Dunn

Publication Date: 2008

$20.00

Recent advances in the realm of polyaspartic ester finish coat technology have led to significant improvements in their aesthetic and corrosion resistance properties. Of particular interest is an initial comparison of the aesthetic properties of older and new generation polyaspartic ester finishes with both polyurethanes and isocyanate-free polysiloxane finishes.

Polyasparatics for Corrosion Protection Applications

Product Number: 41205-208-SG

Author: Edward P. Squiller, Kurt E. Best

Publication Date: 2005

$20.00

This paper describes the polyaspartics coating technology and how it can be used to formulate relatively fast drying 2-coat corrosion resistant paints for use on steel substrates. The polyaspartics coating technology offers several advantages over the conventional two- and three-coat paints, including faster re-coat windows leading to an overall faster coating application process and lower costs.

Polyaspartic coatings can offer excellent performance characteristics typically expected of SSPC Specification Number 36, Level 3, for Aliphatic Polyurethane Topcoats. In addition, polyaspartates will pass an industry standard for corrosion protection in medium corrosivity environments direct to metal. These features offer the typical industrial maintenance customer high performance for gloss and color retention, while reducing application time and costs.

Fouling of equipment surface by unwanted materials is a well-documented problem in
industrial water systems.1 The foulants are generally classified into four categories: a)
mineral scales i.e., calcium carbonate, calcium sulfate, calcium phosphate, magnesium
hydroxide, etc., b) corrosion products i.e., iron oxide, zinc oxide, copper oxide, etc., c)
microbiological mass i.e., bacteria, algae, fungi, and other organisms, and d) deposits
i.e., clay, silt, calcium-inhibitor salts, corrosion products, etc.
