Natural Gas
CH₄+Natural gas is a fossil fuel mixture consisting primarily of methane (70-90%) along with varying amounts of ethane, propane, butane, and trace gases including hydrogen sulfide and carbon dioxide. Natural gas is widely used for heating, electricity generation, cooking, and as an industrial feedstock. The composition varies by source—pipeline-quality gas is processed to meet specifications while raw natural gas may contain higher levels of impurities. Mercaptan odorant is added to detectable levels for safety per federal regulations. The lower explosive limit (LEL) is approximately 5% by volume. Leak detection is critical throughout the natural gas infrastructure from production to end-use, protecting against explosion hazards and methane emissions.
