The SF6 Basics

  • SF6 has proven to be highly efficient in transmission and

distribution equipment and switchgear because of its unique properties such as chemical inertness, high thermal stability, non-flammability, and non-toxicity.

  • Life Cycle assessment studies have proven that using

the SF6 technology leads to considerable environmental advantages.

  • Despite the advantages, SF6 is a potent greenhouse

gas covered by the Kyoto Protocol. Any emissions must be avoided as far as possible and the product must be handled within closed loop systems.

  • Although significant efforts have been made in the past

years, so far no viable alternative to SF6 has been found

  • ffering the same advantages and performance.

SF6 Emission Reduction

In production, filling and quality control

SLIDE 12

SF6 Emission Reduction at the point of production

  • Emission free filling system
  • The use of dedicated piping allow to send to the treatment system

any potential release of gas during filling

  • Plasma burner to treat off-gas streams
  • Due to its exceptional stability, it is essential to reach temperature

>4000°C to efficiently crack SF6

  • Reduction of energy consumption (indirect emissions)
  • Implementation of emission free sampling
  • This allows us to check product quality without causing any emission

into the atmosphere Interventions at our plants

SF6 Emission Reduction at the point of production

Procedure:

  • 1. Connect
  • 2. Vacuum
  • 3. Valve opening
  • 4. Filling with SF6
  • 5. Valve closing
  • 6. Evacuation of residual

gas in filling pipe

  • 7. Residual gas is

collected and reprocessed in the plant

SF6 Emission Reduction at the point of production

The picture shows one of our sampling systems in the plant. The sample cylinders are inserted with fast connectors that do not have “free room” where SF6 might accumulate and be emitted. The sample cylinders are then transported to the laboratory to be analyzed.

  • Direct emissions are measured in the exhaust
  • Continuous analysis (IR und UV) of plant off-gases
  • Emissions (after plasma burner) are analyzed with GC
  • Diffusive emissions are estimated:
  • Emissions caused by gasket porosity are estimated
  • Tightness of connections is regularly checked
  • Procedure is in place
  • Indirect emissions are calculated:
  • Indirect greenhouse emissions caused by energy consumption are

included and are calculated considering the “electricity production mix” of Germany and Korea. Measurement

The SF6 ReUse Process

  • 3 Different Cases -

quality dependent

  • A. Inspection Case
  • B. ReUse Case
  • C. Disposal Case

The SF6 ReUse Process

Solvay ReUse services include

28/05/2014 Presentation title – Entity

  • Offering of special packaging for

used/contaminated SF6

  • Transport arrangements
  • Analysis of used SF6
  • Environmental friendly conversion of used SF6

into new virgin product which meets all specification of virgin SF6 including the non- toxic requirement.

  • Environmentally safe disposal in case the used

SF6 is too heavily contaminated (very rare case)

SF6 ReUse Process

Reprocessed SF6 quantity related to the first amount in 1991 (%)

Due to the treatment of used SF6 within Solvay’s ReUse Process, emissions of more than 15 Mio t CO2 equivalents could be avoided up to now. Almost all returned volumes can be re-processed into new virgin SF6 and only a minor part must still be incinerated due to unacceptable contamination levels (in 2013 less than 1% of return material ).

SF6 Emission Reduction

  • Efforts to reduce SF6 Emissions have to start already at the point
  • f production
  • Not just emissions at the point of use matters
  • Every pound that is used might have already caused some emissions
  • SF6 Emission reduction efforts of the manufacturers should be an integral

and important part of the SF6 purchase decision

  • Solvay contributes in two ways to lower SF6 emissions
  • Direct: strict control over process and filling
  • Indirect: ReUse program for your used SF6
  • Impressive trends over the past years have been demonstrated
