Characterization of 316 Stainless Steel and Inconel C-276 Degradation after Exposure up to 10 Vol Percent H2S at High-Temperatures up to 100 Hours
Abstract
The purpose of this effort was to the study the potential compositional and structural changes in the materials used in the reactor used for the La0.7Sr0.3VO3.86-delta (LSV) sulfur tolerance In-house Laboratory Independent Research (ILIR) project. This effort was deemed appropriate and necessary after it was observed that after approximately 1.5 years of operation, using hydrogen sulfide (H2S) concentrations as high as 10 vol% and temperatures up to 700 deg C, the reactor lid formed a leak producing a small flame, which was a safety hazard. This study investigated if other locations within the reactor were potentially compromised, which could have caused additional safety issues. Additionally, due to the extreme operating conditions, this study took note of any other material changes in the reactor, which would decrease application confidence in using these materials again in future projects.
