The answers may not be obvious when the gas contains appreciable concentrations of carbon dioxide or nitrogen - or - significant amounts of heavier hydrocarbons. Further, in a plant setting, the correct answer to the flammability question may change as the gas passes through the various processes.

WebTo exist as a liquid, H 2 must be cooled below its critical point of 33 K. However, for it to be in a fully liquid state at atmospheric pressure, H 2 needs to be cooled to 20.28 K (−252.87 °C; −423.17 °F). [5] A common … WebThe lean flammability limit is 3.2% H2, 76.5% Ar, and 20.3% 02. This is slightly lower than the value of4% hydrogen in air. The rich flammability limit is 76.4% H2, 18.6% Ar, and 5% 02 which is exactly the same oxygen content for the case of hydrogen in air. For practical purposes the rich limit of 5% 02 is the Web2) is a colorless, odorless, flammable gas which is compressed to high pressure. The flammable range of hydrogen is 4.0% - 75.0 % in air.
