While often simplified as a single commodity, natural gas is a complex mixture of hydrocarbons and other gases, each playing a specific role in its overall composition and function. While nitrogen is inert, its presence dilutes the methane concentration, lowering the overall energy efficiency of the fuel.
Upgrading Facilities for Natural Gas Processing Infrastructure Needs
While methane provides a clean and hot flame, the addition of ethane, propane, and butane increases the total energy content per unit volume. Acid gas removal units capture sulfur compounds and carbon dioxide, while dehydration units eliminate moisture.
Methane (CH4) is the primary constituent, typically accounting for 70% to 90% of the total volume. Carbon dioxide (CO2) is another common impurity; in small amounts, it is manageable, but in high concentrations, it must be removed to prevent corrosion and ensure safe combustion.
Natural Gas Processing Infrastructure for Component Separation and Purity
The remaining volume consists primarily of ethane (C2H6), propane (C3H8), and butane (C4H10), which are classified as natural gas liquids (NGLs) when in gaseous form but condense into liquids under pressure or cooler temperatures. Processing for Purity and Efficiency To transform raw wellhead gas into the clean-burning fuel delivered to consumers, extensive processing is required.
