FE-AGA8-1992


FE-AGA8-1992, Ver. 1.10, Apr 01, 2005, is a program for MS Windows. FE-AGA8-1992 calculates compression factors, mass densities and molar densities of the natural gas mixture at both base and operating conditions using AGA-8/1992.
FE-AGA8-1992 also calculates natural gas supercompressibility factor, gas mixture molar mass, superior calorific value and relative density at three standard pressure/temperature conditions. FE-AGA8-1992 implements AGA-8 in detail and is also in accordance with ISO-6976.

INTRODUCTION
FE-AGA8-1992 calculates the properties of a natural gas mixture completely in accordance with:
  • A.G.A. Transmission Measurement Committee Report No. 8: Compressibility and Supercompressibility for Natural Gas and Other Hydrocarbon Gases, 2nd edition November 1992, 2nd printing July 1994.
The calculation of relative density, superior calorific value and the conversion of volume and mass fractions into mole fractions are in accordance with:
  • ISO 6976:1995/Cor 1:1997: Natural gas - calculation of calorific values, density, relative density and Wobbe index from composition.

RESULTS
FE-AGA8-1992 calculates the parameters of a natural gas mixture at base and operating conditions (pressure & temperature). The range of base and operating pressure varies from 1.5⋅10-5 to 4000 psia (10-7 to 275.8 MPa). The range of base and operating temperature varies from -200 to 760 F (144 to 678 K). You can select the proper unit for pressure (among 24 available units) and for temperature (among 4 available units). The units of output parameters can also be changed. The following parameters are calculated:
  • Compression factor at base conditions
  • Mass density at base conditions
  • Molar density at base conditions
  • Compression factor at operating conditions
  • Mass density at operating conditions
  • Molar density at operating conditions
  • Supercompressibility factor
  • Mixture molar mass
  • Relative density at 0°C and 1.01325 bar
  • Relative density at 15°C and 1.01325 bar
  • Relative density at 20°C and 1.01325 bar
  • Superior calorific value (25°C/0°C/1.01325bar)
From the right side of the parameter select the preferable unit.
