Flammability range of methane
Did you know?
WebAs an example, a mixture of nitrogen and methane is considered flammable according to standard methods when it contains more the 14.3 % methane (ISO 10156, ASTM E-681-01). Mixtures containing less than 14.3 % are incapable of forming flammable mixtures with air upon mixing in any proportion. 4 WebFeb 15, 2024 · In the pure methane scenario, the flammability limit for methane is 9%–17%, and the VDP region is 9%–15%. Compared with the pure methane scenario, the flammability limit range in the methane and liquid coexistence scenarios is increased, which also increases the risk of explosion.
Methane has a boiling point of −161.5 °C at a pressure of one atmosphere. As a gas, it is flammable over a range of concentrations (5.4–17%) in air at standard pressure. Solid methane exists in several modifications. Presently nine are known. Cooling methane at normal pressure results in the formation of methane I.
