Stern, R E

In 1980 a change was made in the rules of first sales of natural gas. The Federal Energy and Regulating Committee issued Order 93, which defines the therm (100,000 BTUs) and decatherm (1,000,000 BTUs). This change has made the determination of the heating value a more definitive part of natural gas analysis because the BTU is now used along with the volume to calculate the price. The accuracy of a gas analysis depends upon the analytical methods. The analytical methods available to determine the heat content, or calorific value, of natural gas are quantitative analysis and combustion calorimetry. The quantitative method involves calculation of the BTU content from a gas analysis. Calorimetry is the measurement of the heat given off in the combustion of a known quantity of gas. A new method introduced by William H. Clingman, Jr. relates the calorific value to the air-to-gas ratio in an adiabatic flame. This presentation contains fundamental thermodynamics of calorimetry and the description of some of the instruments used for BTU measurement.
