WebAug 25, 2024 · Flammability range: LEL=4,3% – UEL=46%. Autoignition Temperature = 500°F. Explosive when mixed with air, depending upon proportion. Burns with a blue flame Burning H2S produces another toxic gas called SO2 (Sulphur Dioxide) Sulphur Dioxide (SO2) is a colorless or transparent gas and is non-flammable. WebThe upper and lower flammability limits of methane in air are located on this line, as shown. The stoichiometric combustion of methane is: CH 4 + 2O 2 → CO 2 + 2H 2 O. The stoichiometric concentration of methane in oxygen is therefore 1/ (1+2), which is 33 percent.

WebHydrogen sulfide has a very low odor threshold, with its smell being easily detected by most people in the range of 0.0005 ppmv to 0.3 ppmv. 2 As the gas becomes more concentrated, the odor increases with a strong rotten egg smell identifiable up to 30 ppmv. From about 30 ppmv to 100 ppmv, the gas is stated to have a sickeningly sweet odor. airbnb slidell louisiana
