Why is Chemical Gas Mixed With Natural Gas?
Natural gas is a combustible mixture of hydrocarbon gases, typically consisting of about 85% methane. It is found in underground deposits and is extracted for use as fuel. Chemical gas is often added to natural gas to give it a distinctive odor so that leaks can be detected. The addition of chemical gas also makes natural gas more visible when burned, making it safer to use. Natural gas is a fossil fuel that is formed when organic matter decomposes under the earth’s surface. This process can take millions of years, and the resulting natural gas is composed of methane and other hydrocarbons. Chemical gas, on …
