FE-ISO12213-3 calculates the properties of a natural gas mixture completely in accordance with:
  • ISO 12213-3:2006: Natural gas - Calculation of Compression factor -
    Part1: Introduction and guidelines
    Part3: Calculation using physical properties
Download "fe_12213x3.exe", the latest version of self-extracting and self-installing demo program. Run "fe_12213x3.exe" and follow the on-screen instructions. The default folder for installation is C:\Program Files (x86)\FE_ISO12213_3.
To enter the parameter just click on the corresponding textbox and type in the value. Before entering the values for pressure and temperature select the corresponding unit at the right side of the parameter. Also select the corresponding reference conditions before entereing the superior calorific value and relative density. Relative density and the superior calorific value can be given at any reference conditions specified in:
ISO 6976: Natural gas - calculation of calorific values, density, relative density and Wobbe index from composition
Note: In a demo version the pressure textbox can not be changed.
To start the calculation select 'Run' from 'Start' menu of your FE-ISO12213-3 menu bar. The error report will be displayed in "Error report" textbox. If the message "No errors!" was displayed the calculation ended successfully.
To save the file select 'Save As' from FE-ISO12213-3 'File' menu. The default file extension is '.sge'
To open the existing file select 'Open' from FE-ISO12213-3 'File' menu.
To print the results of the calculation to your system printer select 'Print' from FE-ISO12213-3 'File' menu.
To print the calculation results into ASCII file select 'Print ASCII to File' from FE-ISO12213-3 'File' menu.
FE-ISO12213-3 calculates the parameters of a natural gas mixture at operating conditions (pressure & temperature). The pressures must be within the range 0.1 Pa to 12 MPa (0.000001 to 120 bar). The operating temperatures must be within the range 263 K to 338 K (-10.15°C to 64.85°C). You can select the proper unit for pressure (24 available units) and temperature (4 available units). You can also enter the superior calorific value and relative density at any reference conditions specified in ISO-6976. The units of output parameters can also be changed. The following parameters are calculated:
  • Compression factor at operating conditions
  • Molar density at operating conditions
  • Mass density at operating conditions
  • Gas mixture molar mass
