Corrosion Mapping in Storage Tank Bottoms Using an Array of Guided Wave Magnetostrictive Transducers

posted 02-24-2024
Be the first person to recommend this.
TRACK: Sustainability/Reliability Above ground storage tanks are used to store various fluids and chemicals across many industries. The structural integrity of these tanks must be regularly assured, but these inspection operations are hazardous due to the chemicals themselves as well as the requirement to operate within confined spaces. The accepted practice for inspection of these tanks, in particular the tank bottoms, requires removing the tank from service, emptying the tank, and interior entry for direct inspection of the structure. An inspection from outside the tank would have significant cost and time benefits and well as a large reduction in the ...

High-Temperature Stable, Hydrophobic Coatings for Anti-fouling Applications

posted 02-23-2024
Be the first person to recommend this.
TRACK: Emerging Technology This presentation will highlight a rare-earth based process for use in antifouling applications. Rather than a traditional coating, the surface of the alloy is modified with rare earth nanoparticles, yielding a very thin oxidized layer that is integral to the alloy. This treatment has no measurable thickness, does not impose any operating temperature limits, protects from high temperature oxidation, and decreases surface energy and polarity leading to low fouling and coking rates. Successfully treated materials include stainless steels, superalloys, and carbon steel. The process is water-based and nonhazardous and has successfully ...

Be the first person to recommend this.
TRACK: Bioprocessing & Corrosion Mechanisms Despite CUI being one of the most prevalent problems in industry, methods for properly managing it are still lacking. There are either too many unnecessary inspections (which wastes money) or not enough (still having failures). New AI-based methods optimize CUI inspections by starting from cause-and-effect diagrams that blend expert knowledge, physics-based principles, and inspection results, properly weighted by one's relative confidence in each. This is a smart approach that learns as it goes. The cost of inspection is accounted for and balanced properly with risk so that the risk reduction due to inspections ...

Nano Bubble Vapor Infusion to Mitigate the Fouling of Heat Exchangers

posted 02-19-2024
Be the first person to recommend this.
TRACK: Emerging Technology Preventing or minimizing fouling within a heat exchanger is paramount to achieving its expected performance functionality. Fouling occurs when tube or plate surfaces are covered by organic or inorganic deposits from the source cooling water. As this chronic condition develops, there are resultant inefficiencies and damage that occur such as diminished heat transfer, pressure drops, MIC and system shut down. These are costly, laborious and energy consumptive for the facility that impact a company Net Zero goals. Many facilities will use tear down and biocides as an acute response to fouling. These methods are used in an emergency ...

Best Practice: AGRU PFA Sheets for Sulfuric Acid Production at the OMV Refinery in Schwechat

posted 02-18-2024
Be the first person to recommend this.
TRACK: Non-metallics The OMV refinery in Schwechat, Austria, operates a wet sulphuric acid plant with a production capacity of about 2.5 - 9.5 t/h. The plant area in which the sulphuric acid is produced by condensation, is subject to high corrosion, in which regular steels and stainless steels would be destroyed quickly. In order to achieve sufficient resistance to this highly aggressive application conditions, a multi-layer structure consisting of four layers was used. However, the structure was chemically attacked and leaking with quite a few years. Due to the apparent down times and the increasing repair costs OMV decided to fundamentally redesign the ...

Be the first person to recommend this.
TRACK: Sustainability/Reliability First commercial use of pressure hydrometallurgical processes in North America started with the invention by Frank A. Forward and subsequent U.S. Patent 2,576,314 (1948) for Extracting of nickel values from nickeliferous sulfide material, using ammonium carbonate solution, and later implemented by Sherritt Gordon Mines Ltd. at Fort Saskatchewan, Alberta, Canada. Acid pressure leaching and sulphide precipitation processes were developed later and implemented at Moa Bay in 1964 for production of mixed (nickel and cobalt) sulphide from laterite ore.
