I asked Gemini Plus about the reaction of M200A (M200A, a proprietary amine-based solvent often associated with gas sweetening or industrial cleaning) and Nitric Acid, as has been reported in the media as the two (2) chemicals involved in yesterday’s tragic event in WV. It has been reported that H2S was involved; yet, reading this AI analysis, I do not see how H2S was generated by this reaction, unless the M200A was “sour” (contaminated with sulfur from gas processing), which is possible. Maybe they had H2S on site, and the explosion caused its release. AI states this reaction produces Hydrogen Cyanide (HCN), which is more toxic than H2S. HCN’s IDLH is 50 ppm, and H2S is 100 ppm.
Here is the analysis…
