3. Four Outstanding Properties of SF6
Unmatched dielectric strength – 2.5x better than air
Arc quenching capabilities – 100x better than air
Thermally Stable – requires high heat to bread down the gas
Self-healing – independent atoms will regenerate after heat source is removed

4. The Basics Of SF6 Super Dense Gas Vapor Density - x5 > AIR
Stays in a vapor form up to deg. F
Safety considerations
Displaces Oxygen
OSHA – exposure 1,000 PPMv
 SF6 Vapor space
 SF6 Liquid level

5. The Basics Of SF6 Super Dense Gas - continued
Helium Vapor Density - x6 < AIR
Sound waves travel faster through Helium

6. Environmental Considerations
SF6 = Global Warming gas
Not an ozone-depleting gas
SF6 – Global wamring potential (GWP) = 22,800
CO2 – Global warming potential (GWP) = 1
SF6 - estimated lifespan = 3,200 years
CO2 - estimated lifespan = 90 years
1 Pound SF6 = 11 Tons CO2

7. Global Warming Potential (GWP)
GWP - Is a relative measure of how much heat a greenhouse gas traps in the atmosphere. It compares the amount of heat trapped by a certain mass of the gas in question to the amount of heat trapped by a similar mass of carbon dioxide
SF6 is a fluorinated gas (F gas) with a high global warming potential

8. Global Warming Potential (GWP)
is a relative measure of how much heat a greenhouse gas traps in the atmosphere. It compares the amount of heat trapped by a certain mass of the gas in question to the amount of heat trapped by a similar mass of carbon dioxide

9. Atmospheric Lifetimes of Long-Lived Halogenated Species
SF6 - estimated lifespan = 3,200 years
CO2 - estimated lifespan = 90 years
The atmospheric lifetimes of the fluorinated gases such as SF6 and CF4 are of concern because of the effects that these long-lived compounds acting as greenhouse gases can have on global climate. If released into the atmosphere, these molecules will accumulate and their effects will persist for centuries or millennia.

10. Atmospheric Lifetimes of Long-Lived Halogenated Species
SF6 - estimated lifespan = 3,200 years
CO2 - estimated lifespan = 90 years

11. 3 Basic Reasons for Madatory Reporting
SF6 is 100% recyclable
All GIE should be leak proof

28. Potential Financial Impact
Company X = 300,000 *MTCO2e
SF6 is sold as a liquefied product
Approx. $5.00 per pound
*contracted pricing directly from supplier
Approx. $16.00 per pound
*generally sold as a premium from third party supplier

29. Potential Financial Impact
Example 1:
300,000 MTCO2e = 30,000 lbs. SF6
30,000 $8.00 per pound = $ 240,000
30,000 lbs = approx $ each = $ 89,000

30. Potential Financial Impact
Example 1:
30,000 lbs between 5 regions
5 regions = Lots of SF6 Handling equipment = $1,000,000

31. Potential Financial Impact
Example 1:
5 regions = 2 substation techs to fill 30,000 lbs. = $60,000
Adequate Training
Field Service Work
Contractors

32. Potential Financial Impact
Example 1:
In total 30,000 lbs. SF6 adds up quick
(x2) $ 480,000
$89,000
Equipment & $1,000,000
(x2) Field Service $120,000
Grand total = $1,689,00
$1,689,000 / 30,000 = $54.30 per pound of SF6

33. Importance of accurate SF6 inventory recording
Cylinder Storage
SF6 is sold as a liquefied product
Purchased by pound (weight)
Separate into 3 categories
Full
Partial
Empty
Consolidate partial cylinders
ONLY return after recording the weight

34. SF6 Reporting Cylinder Storage
Electrical utility industry returns 10-20% virgin products back to supplier.
Cylinders with Non-Return Valves – see below

35. SF6 Reporting Storage cylinders capacity
Tare weight stamp on cylinder – TW
Valve protection cap does not count towards TW

36. Importance of accurate SF6 Reporting
Ensure that a properly calibrated weighing device is used to prevent overfilling storage and that all the gas has been removed from GIE
1 year calibration cycle
Importance of accurate
SF6 Reporting
 Mass Flow meter
Tank # scales 
0.5% Accuracy

37. Reporting Scale Requirements
For flowmeters, the final rule requires a scale accuracy of +/- 1%
For scales, the final rule requires a +/- 1% of the maximum weight of the containers (i.e. gas plus tare) typically weighed on the scale.
 Mass Flow meter
Tank # scales 
0.5% Accuracy

38. Summary Indefinite re-use of recovered SF6 generally possible
Immediate re-use (using CIGRE / IEC standards) of recovered SF6 even in new GIE generally possible
Properly trained personnel will be able to minimize/eliminate handling losses
