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. WebThis research focuses on the flammability limits of light hydrocarbons (methane, propane, and ethylene) and their binary mixtures at normal and elevated conditions. The flammability limits of pure light hydrocarbons, and binary mixtures were determined experimentally at the temperature up to 300ºC and initial pressure up to 2atm. The

"Triangular diagrams are not commonplace. The easiest way to understand them is to briefly go through three basic steps in their construction. 1. Consider the first triangular diagram below, which shows all possible mixtures of methane, oxygen and nitrogen. Air is a mixture of about 21 volume percent oxygen, and 79 volume percent inerts (nitrogen). Any mixture of methane and air will therefore lie on the straight line between p… " - Flammability of methane
