Calculation of Compressibility Factors

1
Calculation of Compressibility Factors

• Method based on AGA-8

2
Different Inputs Different Methods

• 1. Compressibility of fuel mixture
• 2. Detailed method
• 3. Gross characterization method

3
Compressibility of Fuel Mixture

• Select fuel from menu and enter composition
• Click on calculate heating values
• Thats all you are done !

4
Detailed Method

• Select About from the Top Menu
• A new Compressibility menu is added to menu bar

5
Detailed Method

• From the new compressibility menu
• Select detailed characterization

6
Detailed Method

• 1. Select Units

7
Detailed Method

• Enter Gas Composition
• NB You can only select from components already
  defined

8
Detailed Method

• Enter Temperatures and Pressure
• Select what to Calculate

9
Results Detailed Method

• Click on Go

10
Gross Characterization Method

• Used when a component is not found in the
  Detailed Method
• Based on correlation methods
• Needs gross Heating Value and Carbon dioxide
  content for calculation

11
Gross Characterization Method

• 1. From Stoichiometry Select About
• 2. From Compressibility Select gross Heating
  Values
• 3. Select Units
• 4. Select Method

12
Gross Characterization Method

• Enter gross Heating Value
• Enter Specific Density (e.g.. relative to dry Air)

13
Gross Characterization Method

• Select what to calculate

14
Gross Characterization Method

• Enter Temperature and Pressure
• Enter Carbon dioxide content
• Click on Go to calculate

15
Gross Characterization Method

• Results will give you gas compressibility and gas
  density
