Solar Salt has many desirable properties as an intermediate heat transfer fluid including low corrosion rates (<10 μm/yr) at temperatures (T) <600°C, high oxidizing power for capturing tritium, low melting point, and relatively low cost. However, higher temperatures (T > 600°C) and other factors e.g., high flow rates, can significantly increase corrosion rates.

High Temperature Corrosion Quantification in Renewable Diesel and Sustainable Aviation Fuel Applications

Product Number: MECC23-20056-SG

Author: Sridhar Srinivasan, Gerrit Buchheim

Publication Date: 2023

The authors have developed and introduced a molecular mechanistic model that quantifies and predicts simultaneous naphthenic acid and sulfidation (SNAPS) corrosion rates. This was subsequently presented as a definitive mechanistic corrosion prediction framework describing the molecular basis of the model’s reactions, kinetics, and mass transport of reactive organic sulfur compounds (ROSC) to vessel walls . In this molecular model, sulfidation corrosion is calculated for direct heterolytic reaction of ROSC with solid surfaces. As recently reported, % total S and ppm mercaptans are used as input for the ROSC reactions in the model (Figure 1).

In recent years, solar energy technology has received particular emphasis in the interest of reducing CO₂ emissions. Concentrated solar power (CSP) technology received an initial boost from the installation of nine parabolic trough-based electricity-generating systems totaling 354 megawatts of capacity in the 1980’s. Solar One, operational in 1982 and supported by the DOE and an industrial consortium, illustrate utilization of a circulating heat transfer fluid to produce steam to drive a turbine generating electricity. Solar Two in 1996 demonstrated energy storage so that solar power could be generated during the night.¹ In the ensuing decades, additional capacity has increasingly been installed worldwide, comprised primarily of both parabolic trough and central tower CSP technologies, As of 2019, global installed capacity totaled 6.2 GW, with an additional 21 GWh planned of installed thermal energy storage (TES) comprised primarily of molten salts.

High Temperature Hydrogen Attack Life Assessment Modeling and Inspection

Key elements of a technology initiative aimed at developing high temperature hydrogen attack (HTHA) assessment methodologies for equipment and piping operating in hot hydrogen service are presented. Two assessment methodologies have been developed: (1) a Screening Assessment and (2) an Advanced Assessment both of which predict the development of HTHA damage with time. The HTHA assessment methodologies utilize fitness-for-service (FFS) frameworks and are in good agreement with reported HTHA incidents in API 941RP and API 941TR for carbon steel and C-0.5Mo materials. The Screening Assessment provides an improved decision basis by classifying and ranking equipment operating in hot hydrogen service which are tied to recommended action and levels of concern. The Advanced Assessment models through-wall damage progression. Additionally the use of inspection findings as a means of risk mitigation and guidance on inspection interval decisions are also discussed. Select case studies are used to illustrate the advantages of the proposed methods. The developed methodologies provide an improved link between HTHA damage assessment and progression inspection and detection limits damage tolerance and operation severity.

High Temperature Nitridation Resistance of Several Modern High Temperature Ni- and Co-Based Alloys

Product Number: 51323-19011-SG

Publication Date: 2023

Nitrogen or nitrogen-containing gases are widely used or present in industry. Some industry processes utilize nitrogen gas or nitrogen-rich atmosphere to produce specific products at high temperatures, such as use of nitrogen gas (N2) to protect components from oxidation in heat treating or sintering operations and the use of ammonia (NH3) for nitriding purpose during alloy heat-treatment. In the chemical processing industry, ammonia is produced from the reaction of hydrogen and nitrogen with a catalyst under high temperature and pressure conditions. With the presence of nitrogen in these processes, nitrogen molecules can react with alloying elements to form nitrides. In other applications, nitrogen also exists in many combustion processes that use air in the fuel mixture.

High Temperature Oxidation Lifetime Modeling of Commercial NiCr Sheet Material

To increase efficiency a wide range of energy-related applications are pushing components to higher temperatures where environmental degradation can be life limiting. Unlike mechanical properties such as creep there is no simple degradation parameter to capture the time-temperature-thickness limitations of candidate alloys. For simple high temperature oxidation an issue is how to quantify the degradation rate in a manner useful to component designers. A collaborative effort has used 5000 h exposures of 0.2-0.5mm thick commercial alloys at 950°-1050°C for an initial model framework based on the Quadakkers reservoir model and basic assumptions about the failure criteria. The current effort has exposed 0.5 mm thick specimens of one NiCr alloy for 3-20 kh at 900°C in laboratory air to validate and modify the initial model. Research sponsored by the U.S.Department of Energy Office of Energy Efficiency and Renewable Energy Advanced Manufacturing Office Combined Heat and Power Program.
