About AGA8-DC92

The AGA8-DC92 equation of state is the industry standard for calculating thermodynamic properties of natural gas mixtures.

Key Features:
  • Supports 26-component gas mixtures
  • High accuracy for natural gas compositions
  • Covers wide range of pressure and temperature conditions
  • Accounts for component interactions in gas mixtures
  • Used in custody transfer and process design
How to Use:
  1. Enter base conditions (temperature and pressure)
  2. Optionally enter process (line) conditions
  3. Enter gas composition (mole fractions as percentages)
  4. Ensure total composition is between 99.9% and 100.1%
  5. Click "Calculate AGA8 Properties" to get results
Tip: Use the "Sample Data" button to load a typical natural gas composition for testing.
