Its presence requires rigorous removal processes to ensure safety and prevent the formation of sulfur dioxide during combustion, which causes acid rain. Similarly, water vapor must be strictly controlled; when the gas cools, the water condenses and forms hydrates, which are ice-like compounds that can block pipelines.
Natural Gas Chemical Composition and Key Constituents
Natural gas represents one of the most significant energy resources in the modern world, serving as a critical component of the global economy and daily life. Ethane (C2H6), the second most common constituent, is a significant component in what is often referred to as "ethane-rich" gas.
In some regions, hydrogen sulfide (H2S) is a notorious constituent. While not a poison, high concentrations of CO2 reduce the heating value of the gas and can be corrosive to pipeline infrastructure.
Natural Gas Chemical Composition: Key Hydrocarbons and Non-Hydrocarbon Components
Helium, while present in minute quantities, is often extracted from natural gas reserves because of its valuable industrial and medical applications. Another common non-hydrocarbon is nitrogen (N2).
