A Winning Combination of Gases, Naturally

methane_moleculeIDT Energy continues its discussion of the importance of natural gas in our lives, and explores exactly what it is, because at IDT Energy we believe the consumers should know.

Natural gas is actually a combination of several types of hydrocarbon gases. Don’t get nervous, a hydrocarbon gas is just a substance, made up of the elements carbon and hydrogen, which at normal temperatures and pressures exists in the form of a gas. For instance, methane, which composes between 70%-90% of natural gas, (before it is refined), is a molecule made up of four hydrogen atoms for every one carbon atom. Its chemical symbol is therefore CH₄. C stands for Carbon, and H stands for Hydrogen.

Ethane, Propane and Butane, C₂H₆, C₃H₈ and C₄H₁₀ respectively, make up between 0 and 20% of natural gas, before it is refined.  There can also be small amounts of other substances such as, Carbon Dioxide (CO₂), Oxygen (O₂), Nitrogen (N₂), Hydrogen sulphide (H₂S) and rare gases like A, He, Ne, Xe.

After natural gas is refined, it arrives at your home in its pure form, almost entirely methane; ready to work for you, cleanly and safely.
