Natural Gas Properties

Some screens deal with the composition of natural gas. The natural gas properties are:

•Heating Value: Higher heating value (HHV) is the thermal energy produced in Btu/lb of fuel from completely burning the fuel to produce carbon dioxide and liquid water. The latent heat of condensation is included in the value.

•Methane (CH4): The volume, by percent, of methane in the natural gas.

•Ethane (C2H6): The volume, by percent, of ethane in the natural gas.

•Propane (C3H8): The volume, by percent, of propane in the natural gas.

•Carbon Dioxide (CO2): The volume, by percent, of carbon dioxide in the natural gas.

•Oxygen (O2): The volume, by percent, of oxygen in the natural gas.

•Nitrogen (N2): The volume, by percent, of nitrogen in the natural gas.

•Hydrogen Sulfide (H2S): The volume, by percent, of hydrogen sulfide in the natural gas.
