Process Fluid Selection
The first screen of the flow configuration wizard lets you select the process
fluid used in your application. Available fluids include:
• Natural Gas (AGA & ISO)
• Steam
•Gas
•Liquid
• Custom Gas & Liquid

1. Select “Natural Gas” or “Natural Gas (ISO)” from the column with the
“Fluid Designation Category” header.
2. Select the characterization method for gas compressibility the 3095
Engineering Assistant will use to calculate the natural gas
compressibility factor. Gross characterization is a simplified method
that is acceptable for a narrow range of pressure, temperature, and
gas composition. Detail characterization covers all pressure,
temperature, and gas composition ranges for which AGA8 computes
compressibility factors. Table 3-2 identifies the acceptable ranges for
both of these characterization methods. For ISO Natural Gas, Molar
Composition Method is similar to the Detail Characterization Method,
and the Physical Property Method is similar to Gross Characterization
1 Method.
