Range selection :

Methane is an important fuel and the main component of natural gas, accounting for about 87%. In standard pressure room temperature environment, methane is colorless and odorless; the special taste of domestic natural gas is an artificial odor added for safety, usually methyl mercaptan or ethyl mercaptan. In an atmosphere of atmospheric pressure, the boiling point of methane is −161 ° C. As long as the gas content in the air exceeds 5% to 15%, it is very flammable. Liquefied methane will not burn unless in a high-pressure environment (usually 4 to 5 atmospheres). Chinese national standards stipulate that methane cylinders are brown and white.
