Representative Upper-Bound H2S Concentrations by O&G Supply Chain Process Step

For process steps where publicly available measured data is limited — including gas processing, sulfur recovery, and refining — engineering process models and published process descriptions were used to estimate representative upper-bound concentrations. Midstream transmission concentrations are based on open FERC gas tariff agreements.
