Abstract: Thermodynamic properties of a natural gas stream can be determined in real time utilizing modeling algorithms in conjunction with one or more sensors for quantifying physical and chemica l properties of the natural gas. Related techniques, apparatus, systems, and articles are also described. A method and apparatus for determining the energy content of a gas stream in which spectroscopic measurements on carbon dioxide and hydrocarbons as well as a third measurement of temperature, pressure and sund velocity of the gas are input to a processor which uses an algorithm to calculate the energy contact.
