    Components of Natural Gas other than Methane

          Natural gas is a mixture of methane, with lower amounts of other hydrocarbons and other substances. These other constituents modify the physical and chemical characteristics of natural gas, for example, inert gases make the natural gas heating value lower. The substances that can be in natural gas are: • Carbon dioxide • Nitrogen • Hydrogen sulphide Heavier hydrocarbons which can be separated to give condensate (gasoline) Water vapour is always contained in natural gas. Carbon Dioxide (CO2) The content in CO2 varies from traces to very high amounts. It forms from the reaction of field water with silicates and carbonates. Even a minimal presence of carbon dioxide in natural gas saturated with water forms…
