Tremendous attention has been devoted to understanding the behavior of common engineering alloys in high temperature hydrogen service. Nelson curves from API RP 9411 are available for the alloys most widely used in HTHA service. However, the aging international fleet of equipment in hydrogen service, across the refining, petrochemical and fertilizer industries means that in-service equipment constructed from less-common alloys must sometimes be evaluated for HTHA. The authors are involved with an 10-year joint industry project studying HTHA. One major outcome of this project is a volumetric HTHA damage FFS model which incorporates stresses from methane pressure within the material into an MPC Omega Multiaxial damage formula. A crack growth model using the fracture mechanics parameter C* (commonly used in creep crack growth)12 is also under development. These two are related in that the C* crack growth law parameters can be calculated utilizing the MPC Omega material creep properties. With sufficient creep data for an uncommon alloy like C-0-.3Mo, lot centered MPC Omega creep properties can be regressed. Such data have been compiled by the authors and resulting Omega creep properties are reported. These creep properties, along with other material properties, are used in the HTHA damage progression and the C* crack growth models. Model predictions using this approach are compared to historically available ex-service HTHA data from API RP 9411 for alloys with Mo contents between that of carbon steel and C-0.5Mo. Selective testing (creep and crack growth testing in both air and hydrogen environments) is in-progress to verify the FFS approach.

The carbon footprint of assets will increasingly be of importance to obtain beneficial, economic, social and environmental outcomes of design and engineering projects. Inclusion of a Next Life strategy at asset or product end-of-life can significantly reduce the greenhouse gas (GHG) emissions of First Life assets and Next Life reuses compared to the same uses made from virgin material or recycled content. Traditional engineering design and asset management often only plan for initial use and the management or maintenance strategies necessary to extend First Life, where the First Life is the primary engineering role of the asset. Critically missing from this picture are the costs and environmental impacts incurred throughout the asset or product lifecycle, especially associated with the end-of-life of an asset. A Next Life optimization process for these decisions is described herein that can aid in maximizing the overall Materials Sustainability and Materials Utility (i.e., longevity of fruitful usage) embedded in assets. It consists of appraisal, brainstorming, partnering and evaluation of beneficial impact for particular Next Life options allowing the benefits they can provide to First Life and Next Life opportunities. These benefits can include a reduction in carbon footprint over a lifecycle, cost savings related to GHG emissions, cost savings related to reused material/labor for Next Life assets, or other beneficial impact (even if increased financial cost). The process includes a qualitative conceptual assessment that can feed into a more detailed quantitative assessment for optimization of Next Life materials usage.
