What is the upper limit for the oxygen content in natural gas?

The main components of natural gas are alkanes, with methane accounting for the vast majority; there are also small amounts of ethane, propane, and butane. In addition, it generally contains hydrogen sulfide, carbon dioxide, nitrogen, and water vapor, as well as trace amounts of inert gases such as helium and argon. Natural gas is lighter than air, so it disperses easily, but when it is in a confined space such as a house or tent and reaches a certain concentration in relation to the air, it can explode. The lower explosive limit of methane in air is 5%, and the upper limit is 15%. So, natural gas is basically within this range as well.
Could you tell me where the data showing 15% comes from?
The explosive limit of natural gas at 5%-----15% means that the proportion of natural gas in the air ranges from 5% to 15%. Data source: \"Theory of Natural Gas Processing\".
Your question is phrased incorrectly. The people mentioned above believe that the main component of natural gas is methane, and it’s also correct to use the explosive limit of methane to understand the oxygen content in natural gas. If we go by what everyone understands, does it mean that the oxygen content in natural gas needs to be over 15%? So, your question is too general and not clear enough. For example, the oxygen content during the replacement process in natural gas facilities should be controlled at less than 5%, rather than within a certain range.
