Natural gas is primarily which hydrocarbon component?

Natural gas is primarily which hydrocarbon component?

• A. Ethane
• B. Methane
• C. Propane
• D. Butane

Answer: (B)

Methane dominates natural gas. It is the simplest hydrocarbon and the lightest member of the hydrocarbon family, so it stays as a gas under normal conditions and makes up the largest share of most natural gas deposits. This is why natural gas is described as primarily methane—typically about seventy to ninety percent by volume. The heavier hydrocarbons (ethane, propane, butane) are present in smaller amounts and are usually removed or separated during processing to meet pipeline and fuel specifications. Understanding this helps explain why methane is the defining component of natural gas.
