FE_SGERG_88, Ver 1.20 is a program for 32-bit MS Windows.

FE-SGERG-88 calculates the following properties of a natural
gas mixture:

1. Compression factor
2. Molar density
3. Mass density
4. Gas mixture molar mass


The calculations are completely in accordance with:

ISO 12213: Natural gas - Calculation of Compression factor
 - Part1: Introduction and guidelines
 - Part3: Calculation using physical properties

The 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

INSTALLATION:
Download "fe_sgerg.exe" a self-extracting demo program. Run
"fe_sgerg.exe" and follow the on-screen instructions. The
default folder for installation is c:\ProgramFiles\fe_sgerg_88.

RUN FE-SGERG-88:
After completing the installation run the program using the
'Start' menu of your task bar or double click the fe_sgerg_88.exe
from your Windows Explorer.

ENTER DATA:
Note: In a demo version the pressure textbox can
not be changed. After registering at http://order.kagi.com/?ZQU
you will receive the registration data with which you will
be able to unlock the pressure textbox.
To enter the parameter just click on the corresponding textbox
and type.
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.

START THE CALCULATION:
To start the calculation select 'Run' from 'Start' menu of your
FE-SGERG-88 menu bar. The error report will be displayed in
"Error report" textbox. If "No errors" was displayed the calculation
ended successfully.

FILE SAVE:
To save the file select 'Save As' from FE-SGERG-88 'File' menu. The
default file extension is '.sge'

FILE OPEN:
To open the existing file select 'Open' from FE-SGERG-88 'File' menu.

FILE PRINT:
To print the results of the calculation to your system printer
select 'Print' from FE-SGERG-88 'File' menu.

PRINT ASCII TO FILE:
To print the calculation results into ASCII file select
'Print ASCII to File' from FE-SGERG-88 'File' menu.

RESULTS OF CALCULATION:
FE-SGERG-88 calculates the parameters of a natural gas mixture
at operating conditions (pressure & temperature).

The range of operating pressure varies from 0.1 Pa to
12 MPa (0.000001 to 120 bar).
The range of operating temperature varies from 263 K to 338 K
(-10.15°C to 64.85°C).
You can select the proper unit for pressure (among 24 available
units) and temperature (among 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:

1. Compression factor at operating conditions
2. Molar density at operating conditions (selection among 2 units)
3. Mass density at operating conditions (selection among 10 units)
4. Gas mixture molar mass

From the right side of the parameter select the preferable unit.
