Combustion Flame Speeds and Stability of Associated Natural Gas with High Concentrations of C₂–C₄ Alkanes

Associated gas worth of tens of billions of dollars is flared annually during oil and gas production, which leads to resource waste and environmental issues. The combustion characteristics of associated gas mixtures with high concentrations of C2–C4 hydrocarbons, sometimes called high-BTU gases, were examined in this study. Specifically, adiabatic laminar flame speeds and combustion stability, including critical heat loss at extinction, were...
